^aNumerous glyphosate-based products have recently become available. Known products are detailed in the table of Roundup and glyphosate-based products on page 73. Registered crops, uses, product rates and surfactant requirements vary from product to product and labels change. Check label before using a glyphosate-based product.

Key to abbreviations: Crops: AL = Alfalfa O = Oats B = Barley PT = Potatoes CA = Canola (rape) RG = Rye CL = Clovers SC = Sweet corn/Popcorn DB = Dry beans SF = Sunflower FG = Forage grasses SG = Small grains FL = Forage legumes T = Tobacco Timings: FA = Fall FY = Following year

Notes: This table applies to the major field and forage crops of Missouri. Refer to the herbicide labels for the latest recrop and rotation information for horticultural crops. The University of Missouri does not warrant herbicides and regrets any omissions or errors in this guide. Always refer to product labels before using a pesticide or replanting into treated fields.

A “successful bioassay” where the rotational crop is test planted in soil from the field in question is often required for unlisted crops. A bioassay can be performed in the field or in a container (flower pot) indoors. If possible, similar, untreated soil (such as from an adjoining fence row) should also be planted as a check. A bioassay is also advisable if weather conditions have been unfavorable for herbicide breakdown (cool temperatures and little rainfall) or when you are planting extremely close to the specified rotation interval. Soil sampling should be thorough. Use the same procedures as for fertility samples. If possible a hypersensitive plant should be planted in addition to the desired crop (for example, a grower who is planting wheat but is concerned with potential atrazine carryover should use both wheat and soybeans as test crops since soybeans are also sensitive to atrazine). Field bioassays, where strips are planted perpendicular to the previous crop rows, are also useful.
