• Peach rosette mosaic decline

    Disease

    This disease occurs only in Concord and Catawba grapes in Michigan. Symptoms appear 3 to 4 years after infection. The plant canopy is umbrellalike with shortened and crooked internodes. Leaves are misshapen with a flattened base. Clusters are scraggly and may shell berries. Infected vines lack vigor, are prone to winter injury and may die after several years. The virus is spread by nematodes, infected planting stock and grape pomace. The virus also infects peaches and perennial weeds such as dandelion, horse nettle and curly dock. Boron deficiency and fanleaf degeneration may mimic this disease.

  • Peach scab

    Disease

    On fruit, lesions begin as small, greenish circular spots that gradually enlarge and darken as spore production begins. These spots appear when fruit are half grown and are most common on the stem end of the fruit, but can occur over the whole surface.

  • Peach tree short life (PTSL)

    Disease

    Trees in their third to sixth year show a sudden wilt and collapse of new blossoms and death of branches, with tree death following within weeks of initial symptoms. The bark of affected trees appears reddish and water-soaked and gum exuding from these tissues often has a "sour sap" odor.

  • Peachtree borer

    Insect

    Adult is a clear-winged, metallic-blue moth that has one broad orange or two or more yellow bands across the abdomen; both sexes have more amber sheen on wings than lesser peachtree borer adults.

  • Pear midge

    Insect

    The adult resembles a very small mosquito or gnat; the body is brown and the wings transparent with simple veins. The larva is a white maggot with no legs or visible head; the posterior end is blunt, and the front end tapers to a point.

  • Pear rust mite

    Insect

    The overwintering stage is a light brown, wedge-shaped adult, which cannot be seen without a 15X hand lens. The summer forms are nearly white in color, and even smaller than the overwintered adults.

  • Pear scab

    Disease

    Lesions on leaves begin as pinpoint spots, enlarging and becoming velvety brown to olive green with indistinct margins. Older lesions may remain singular or coalesce with other leaf lesions; they eventually stop expanding and develop distinct margins.

  • Pear slug (Pear sawfly)

    Insect

    The adult looks similar to a small, black-bodied wasp with the ventral side and legs yellow in color. The larva is small, fleshy, dark green to orange, slug-like, and slime-covered, with the front part of the body enlarged.

  • Pear stony pit

    Disease

    Dark-green spots appear on developing fruit about two to three weeks after petal fall. The tissue around the affected areas continues to grow, forming deep pits.

  • Pear thrips

    Insect

    Adult is slender and brown, with short antennae and a swelling behind the head; the wings are long and narrow, with fringes of long hairs.

  • Pear vein yellows

    Disease

    Faint, yellow vein banding, particularly of the secondary veins on current year’s growth, is the most common symptom.

  • Pearleaf blister mite

    Insect

    The adults are very small and cannot be seen without a 15X hand lens; the body is white and elongate oval in shape, like a tiny sausage.

  • Perennial canker of apple and pear

    Disease

    Branch lesions are elliptical, sunken, and orange, purple, or brown in color. A raised layer of callus tissue forms around the infected tissue to isolate the diseased tissue.

  • Perennial canker of stone fruit

    Disease

    Small twig infections are usually found around winter-killed buds, leaf scars, and picking and pruning injuries. They appear as sunken discolored areas with alternating zonation lines and may ooze amber gum unless the twig is killed.

    Insect

    Adults are wedge-shaped, nearly black, with red eyes and red-orange wing veins. The clear wings are held tent-like over the body.

  • Phomopsis cane and leaf spot

    Disease

    Infected leaves have small, yellowish spots with dark brown centers and may be puckered. On petioles, shoots and rachises, elongated black spots or streaks develop that make the tissue brittle. Most shoot lesions occur on the basal three to six internodes. Young tissues are most susceptible. Symptoms appear 21 to 30 days after infection. Rachis and berry infections become apparent later in the season. Infected rachises wither, causing berries or entire clusters to drop prematurely. Berries turn brown and shrivel. Prolonged rainy, cold weather in spring and early summer promotes the disease. The optimum temperature for infection is between 59 and 68ºF (15 to 20ºC). The fungus overwinters in bark of infected canes.

  • Phony peach disease

    Disease

    The canopy of infected trees is flattened and compacted due to shortening of the internodes; the foliage tends to be a darker green. Infected trees may also flower and set fruit earlier, bear smaller fruit, and may suffer a substantial reduction in yield.

  • Phytophthora root, crown, and collar rot

    Disease

    Crown and collar rot are often and mistakenly used interchangeably. Collar rot refers to infection that affects the bark tissue of the scion portion of the tree at or just below the soil line, whereas crown rot affects the bark tissue of the rootstock portion of the tree.

  • Phytoseiid mites

    Beneficial

    A dark mark in the form of an "H" sometimes appears within their body. This mark is red when they feed on European red mites and yellow when they feed on twospotted spider mites. They move very rapidly on the leaves.

  • Pierce’s disease

    Disease

    Initially, only a few shoots start to show symptoms in mid- to late summer. Leaves show scorching from the margin inwards and drop off, leaving the petiole attached to the shoot. Flower clusters may set berries, but these tend to dry up. In fall, infected shoots mature in a patchy manner, leaving “islands” of green tissue surrounded by dark brown mature wood. In spring, bud break on infected vines may be delayed as much as 2 weeks, and new shoots are stunted. An infected vine may die the first year after infection or may live for 5 or more years, depending on the cultivar, the vine’s age and climatic conditions. Pierce’s disease is caused by a bacterium that lives in the xylem and is vectored by sharpshooter leafhoppers and spittlebugs. The bacterium is present in native plants such as grasses, sedges, bushes and trees. The range of insect vectors determines the range of the disease.

  • Pistol casebearer

    Insect

    Disease

    Infections occur soon after blossoms open and are first evident on fruits when they reach 6–12 mm in diameter. Symptoms first appear as white to off-white spots or blisters that enlarge rapidly to cover the entire fruit.

  • Plum pox virus

    Disease

    There is considerable variation in symptoms, depending on which species of stone fruit is affected, variety, age, and general nutritional status of the tree. On leaves, symptoms may include vein yellowing, banding, or the formation of light green to yellow rings.

  • Plum rust mite

    Insect

    Plum rust mites (PRM) generally restrict their feeding to new foliage, causing these leaves to brown and roll upward longitudinally

  • Plum rust mite (Peach silver mite*)

    Insect

    Poison ivy is a trailing or climbing vine common to woodlots, naturalized areas, and property boundaries.

  • Potato leafhopper

    Insect

    All leafhopper species feed on the undersides of leaves, puncturing cells and sucking out the contents. In general, juice grape (labrusca) varieties are much more tolerant of leafhoppers than hybrid or vinifera varieties.

  • Powdery Mildew

    Disease

    Turf affected by the disease have a grayish white cast, with initial symptoms appearing as white patches on the leaf blade.

  • Powdery mildew

    Disease

    Powdery mildew can infect all green tissues and give them a white to gray, powdery appearance. Colonies occur mostly on the upper leaf surface. Early berry infections can result in split berries, secondary rots and undesirable flavors in wine. Late berry infections are less obvious but can still predispose the berries to rots. In late summer, the fungus produces small, brown to black fruiting bodies (cleistothecia) on infected plant parts. Cleistothecia overwinter in bark crevices and release ascospores when exposed to moisture between bud break and fruit set. In regions with mild winters, the fungus can also survive in dormant buds, which develop into “flag shoots.” Powdery mildew is favored by high humidity and temperatures of 68 to 81 degrees Fahrenheit (20 to 27 C). Wetness is not required for infection. Temperatures above 95 F (35 C) inhibit new infections. Begin monitoring early in the season, focusing on shaded leaves and clusters inside the canopy.

  • Powdery mildew of apple and pear

    Disease

    The fungus overwinters in leaf buds and sometimes flower buds. Mycelium develops rapidly on unfolding leaves and appears as white, felt-like patches or as a solid mat on the upper or undersurface of the leaf.

  • Powdery mildew of apricot, nectarine, peach and plum

    Disease

    Infection appears as white circular lesions of patches of powdery growth on either side of the leaf, or on the terminal ends of new shoot growth. Severely infected leaves curl upward or blister, may be stunted, but eventually drop as infection progresses.

  • Powdery mildew of cherry

    Disease

    The fungus attacks young leaves and shoots and tends to cause more damage on sour cherry than sweet cherry. Infections appear as white circular lesions or patches of powdery growth on either side of the leaf or on the terminal ends of shoots.

    Disease

    Affected trees appear weak and show a general decline. Leaves may have upward cupping, turning prematurely yellow or reddish purple, droop, and then prematurely drop. The bark is abnormally thick and spongy and the wood underneath has a severely pitted, indented texture. Symptoms are most severe in the wood just above and below the soil line.

  • Purple Deadnettle

    Weeds

  • Pythium Blight

    Disease

    Pythium first appears as circular reddish brown spots in the turf, ranging in diameter from 1 to 6 in. In the morning dew, infected leaf blades appear water soaked and dark and may feel slimy.

  • Quackgrass

    Weeds

    Quackgrass is a common grassy weed of turfed areas. Quackgrass is a perennial and can often be spotted by its dull blue-green appearance. Because quackgrass spreads by rhizomes (underground stems) it responds very well to cultivation practices. It is common to have quackgrass contamination in unscreened topsoil. Each rhizome section has the ability to produce a new plant.

  • Quince rust

    Disease

    Attacks only the fruit of apple and pear. Symptoms begin as a purplish lesion, usually appearing on the calyx end of the fruit. As the disease progresses, the entire calyx end becomes blistered and deformed. Tube-like structures eventually form and produce powdery, bright orange spores.

  • Red Sorrel

    Weeds

    Red sorrel is a perennial weed of low-maintenance sites characterized by dry, infertile and often low pH soils. Red sorrel will survive at neutral pH but is usually not as prevalent because the turf will be more competitive under these conditions.

  • Rhizopus rot

    Disease

    Although the rot is predominantly a postharvest problem, symptoms may also develop in the field. Rotted fruit appears similar to brown rot, but Rhizopus-affected fruit appears slightly darker, the skin may slip away from decaying flesh underneath, or the fruit may be very leaky.

  • Ripe rot

    Disease

    Initially, berries show circular, reddish brown spots, which enlarge to cover the whole fruit. Salmon-pink fungal spore masses develop in a circular pattern on the fruit surface. The berries shrivel and darken as they decay and then fall to the ground. Berries are susceptible to infection at all stages of development but do not show symptoms until the berries are ripe. Disease development is favored by wet weather and temperatures of 77 to 86ºF (25 to 30ºC). The fungus overwinters in mummified fruit and infected pedicels, from which spores are dispersed in spring and early summer. Spores produced on rotting berries can infect neighboring berries.

  • Root-lesion nematode

    Disease

    Root-lesion nematodes are microscopic, migratory endoparasites that feed on the root systems of many crops. Affected trees appear stunted, may exhibit chlorosis or yellowing of the leaves, and have poor yields; young trees may be killed.

    Disease

    Rupestris stem pitting virus causes a slow decline of vinifera cultivars and interspecific hybrids. The main symptoms are delayed bud break, poor spring growth, stunting of infected plants and a decline in yield. No leaf discoloration is observed. When the bark is peeled off the trunk, the wood may reveal the presence of small pits. This virus mainly spreads via planting material.

  • Rust

    Disease

    Rust diseases are characterized by yellow to dark brown urediospore infestations that, from a distance, make turf stands appear orange or yellow.

  • Rusty spot

    Disease

    Lesions begin as small, circular, tan to orange blemishes approximately 3–5 mm in diameter. The discoloration is due to discoloring of the fuzz on the fruit.

  • San Jose scale

    Disease

    Septoria leaf spot, also called méelanose, mainly affects American Vitis and muscadine grapes. Angular, reddish brown to black spots 1 to 2 mm in diameter appear after midseason. Nearing veraison, lesions become larger with diffuse margins. Fruiting bodies may be seen with a hand lens. The area surrounding the spots may be yellow. The fungus overwinters in infected leaf debris.

  • Shepherd's Purse

    Weeds

    Shepherd's purse is a winter annual with a basal rosette of lobed leaves and a long flowering stalk. Leaves become more deeply lobed as they mature. Due to extremely long-lived seeds and an affinity for disturbed soil, it is most often a weed of new seedings established between mid-August and the end of September.

  • Shothole borer

    Insect

    The adult is stocky with a hard black body and antennae, leg segments and tips of elytra reddish brown; its head is not visible from above.

  • Silver leaf

    Disease

    Silvering of the foliage is the characteristic symptom. At first, silvering may be associated with only one or two major branches, but eventually the entire tree becomes silvery in appearance. When infection is severe the leaves may curl upward.

  • Silvery Thread Moss

    Weeds

    Silvery thread moss is the most common species found in turfgrass, usually appearing on putting greens and in shaded back yards.

    Insect

    The adults are 3/4 inch long silvery or cream colored moths that fold their wings length-wise over their abdomen into a tube shape when at rest. Webworm moths also have soft mouthparts that project forward on the head (hence, they are called snout moths). The adults can be seen flying over lawns at various times during the summer, but this does not indicate a problem unless very high numbers are observed.

  • Sooty blotch

    Disease

    Sooty blotch and flyspeck are found together on the same fruit and affect only the epidermal layer of the fruit. Sooty blotch appears as various shades of olive-green on the surface of the fruit.

  • Sour bunch rot

    Disease

    Sour rot is a wet rot that spreads rapidly throughout clusters and smells like vinegar. It is caused by acetic acid bacteria and various undesirable yeasts and fungi. Unlike Botrytis bunch rot, it usually lacks fungal sporulation. Low-grade powdery mildew infections and grape berry moth infestations can predispose clusters to infection. Fruit flies are common and help spread the disease. Tight-clustered cultivars are more susceptible than others. Prolonged periods of wetness or high relative humidity are conducive to sour rot development.

  • Sour cherry yellows

    Disease

    Young leaves develop chlorotic yellow rings or mottle; shot hole may occur in severe cases or as lesions age. These symptoms rarely recur after the first year of infection.

  • Southern blight

  • Tall Fescue

    Weeds

    Tall fescue is a clumping perennial cool-season turfgrass. Its coarse texture and aggressive growth habit make it objectionable in many situations because it does not mix well with other turfs.

  • Tar spot

    Disease

    Tar spot is a minor disease that occurs mostly on wild grapevines. This fungal disease is characterized by black, slightly raised spots about 1/12 to 1/6 inch (2 to 4 mm) in diameter. A spot may be surrounded by a circular brown halo up to 2/5 inch (1 cm) in diameter. The fungus overwinters in these spots. In the spring, they release airborne spores, which infect the new leaves.

  • Tarnished plant bug

    Insect

    The adult is brown and the extremities of its wings are translucent with a cream-colored scutellum on its back. The nymph is pale green; from the 3rd nymphal stage, it has five black points on the back.

  • Thrips

    Insect

    Feeding by thrips, particulary Frankliniella occidentalis, can cause scarring on fruit. During bloom, thrips feed on pollen and small berries.

  • Tomato/Tobacco ringspot decline

    Disease

    These diseases occur sporadically in vinifera grapes and interspecific hybrids. Labrusca grapes are resistant. In the first year of infection, a few leaves may show mottling. The second year, new growth is generally sparse because infected buds are prone to winterkill. Infected vines show shortened internodes with small, distorted leaves and sparse fruit clusters with uneven ripening. The third year, growth is very stunted and limited to basal suckers, and the vine eventually dies. Dead and dying vines are usually present in a roughly circular pattern in the vineyard. The viruses are introduced into vineyards with infected planting stock or by dispersal of seed from infected weeds. The virus is then spread by dagger nematodes feeding on roots of infected plants. The nematodes can retain the virus for long periods. Both viruses infect common weeds such as dandelion, sheep sorrel, common chickweed and red clover. Tomato ringspot virus also infects many fruit crops. These viruses may already be present in land used to establish new vineyards.
