New insecticide label information for compounds listed in 2021 E0154

MSU Fruit Management Guide E0154 product numbers are in parenthesis ().

Avaunt eVo (55) (indoxacarb) is a member of the oxadiazine class of insecticides with a novel mode of action that acts by inhibiting sodium ion entry into nerve cells, resulting in paralysis and death of the pest species.  Avaunt Evo is registered for use in pome and stone fruits, blueberries and grapes for control of plum curculio, tarnished plant bug, oriental fruit moth, codling moth, leafrollers, plum curculio, Japanese beetle, fruitworms and leafhoppers.  The primary route of entry into the target pest is by ingestion, although the product is also absorbed through the insect cuticle.  Because of this, thorough coverage of the crop is critical for good pest control.  Avaunt is relatively short-lived in the environment, but has particularly good rain-fast characteristics. The maximum yearly amount of Avaunt Evo can be applied is 24 ounces in pome and stone fruits, 12 ounces in grapes and blueberries.

Sivanto HL (15) (flupyradifurone) belongs to the butenolide class of insecticides, which are agonists of insect nicotinic acetylcholine receptors (nAChR). Sivanto HL is registered in pome and stone fruits, grapes, caneberry, saskatoons, and blueberries for control of several sap-feeding insects, including of aphids, leafhoppers, psylla, scale insects, and gall wasp and blueberry maggot in blueberries. It is also registered in grape for control of leafhoppers and mealybugs. Sivanto HL displays translaminar movement when applied to foliage, and is xylem mobile when applied to soil via root uptake. It has shown to be relatively safe on many beneficials, including honey bees. Sivanto HL contains two times the active ingredient as Sivanto Prime, thus the maximum yearly amount that can be applied is 14 fluid ounces in pome and stone fruits, grapes, caneberries or bushberries per season, and per acre rates are adjusted to account for the double concentration.

Spear-T (35) (GS-omega/kappa-Hxtx-Hv1a) is a peptide-based biopesticide labelled for pome and stone fruits, blueberries, caneberries, strawberries, and grapes for control of spotted wing drosophila, psylla, and mites. Spear functions as a central nervous system inhibitor. Spear-T has a zero-day pre-harvest interval and is relatively non-toxic to mammals, birds, fish, honey bees and other beneficial insects.

Senstar (37) (spirotetramat plus pyriproxyfen) is an insecticide that combines two active ingredients as a pre-mix formulated compound. It registered for use on pome and stone fruits, blueberries and grapes for the control of aphids, scale insects, psylla, mealybugs, and gall midge. The maximum yearly amount of Senstar that can be applied is 36 fluid ounces (0.281 pounds active ingredient spirotetramat plus 0.098 pounds active ingredient pyriproxyfen) in pome fruits, 30 fluid ounces in stone fruits, 25 fluid ounces in grapes and 30 fluid ounces in blueberries.

Venerate (7) (Burkholderia rinojensis) is a mixture of metabolites produced by the bacterium during fermentation and the formulated product contains no viable cells. Venerate is labelled for pome and stone fruits, blueberries, caneberries, strawberries, and grapes, and is listed by the Organic Materials Review Institute (OMRI) for use in organic production. Venerate is labelled for control of a range of leafrollers, fruitworms, and plum curculio, and suppression of aphids, mites, thrips and stink bugs. The proposed mode of action is exposure to spray deposits and as a stomach poison. The use of a non-ionic adjuvant is recommended. Zero-day pre-harvest interval and 4-hour restricted entry interval (REI).

Jet-Ag (hydrogen peroxide and peroxyacetic acid) is an acidic oxidizing agent that is a fungicide and bactericide, registered for use in various agricultural crops. It provides short-term control of microbial communities, providing many in-field and post-harvest uses. The oxidizing activity of Jet-Ag can disrupt the normal performance of insects that are closely tied to microbes, such as spotted wing Drosophila. It is registered for use in organic production, but note the corrosive nature of the product and take appropriate precautions.

Nealta (4) (cyflumetofen) is a beta-ketonitrile class miticide with a METI 2 (Group 25 acaracide) mode of action, labeled for use on pome and stone fruits and grapes. Nealta provides knock-down and residual control of tetranychid mites such as European red mites and twospotted spider mites. Nealta will control all life stages of these mites, including eggs, nymphs and adults. Because Nealta is not systemic, thorough coverage of plant surface is necessary for effective control. Nealta is relatively safe to beneficial arthropods. The maximum yearly amount of Nealta 200SC that can be applied is 27.4 fluid ounces (two applications).
