There may be no better phrase to describe the world we live in today. More emphasis on sustainability and where our food comes from grows the need for continuing research in agriculture.
Weed Control in Michigan Christmas Trees
Weed Control in Christmas Trees, 2015 - Extension Report # E-3237
Dr. Bernard Zandstra does research on weed control in fruit, ornamental, and vegetable crops. Current projects include weed control in seedling Christmas trees, reduced rates of herbicides in vegetable crops, and new herbicides for residual control in fruit crops. Dr. Zandstra authors the Michigan Weed Control Guide for Vegetable Crops bulletin and the weed control section of the Michigan Fruit Management Guide. He also is Field Research Director of the IR-4 Center (National Program for Minor Use Registrations) at Michigan State University. Dr. Zandstra does weed control research on most vegetable crops, including asparagus, snapbean, carrot, celery, sweet corn, cruciferous crops, cucumber, edamame, herbs, lettuce, mint, onion, pepper, squash, and tomato. His research in fruit crops includes strawberry, apple, blueberry, cherry, grape, peach, and raspberry.
The Herbicide/Weed database is an interactive tool to assist in herbicide selection. Users can select from multiple options, such as crop type and weed species, to determine which herbicides could help with their particular weed control needs.
This database is intended to be a resource for choosing herbicides: it is not a replacement for any information contained on labels. Always check product labels before applying herbicides to any crop.
