CHEMICAL 1). Know the weed history f your fields and plan ahead. Proper weed identification is critical. Timely herbicide application is essential to maximize weed control. you need to know he proper dry bean and weed growth stage to apply the herbicide. 2). Dry beans are used for human consumption. ALWAYS FOLLOW HE LABEL DIRECTIONS. IT IS ILLEGAL TO USE CHEMICALS THAT ARE NOT LABELED. MECHANICAL 1). Work seed bed similar to sunflower and soybean conditions. 2). Rotary hoeing your dry beans is an option for weed control. Rotary hoe after the first trifoliate and not after the third trifoliate stage. There is less potential damage to the dry beans if you rotary hoe when temperatures are warm and the plants are more flexible. Rotary hoe when weeds are small or in the "white stage". This will give you the most effective results with the hoe. 3). Cultivate as needed. As the dry bean plants grew, there is greater chance of pruning the roots. You can tell you are pruning the roots if you lift up your cultivator and the shanks have many fine white root hairs on them. Pruning the roots can delay the plants maturity. The dry beans have to put energy back into growing the roots and this slows the top growth. Root pruning during the reproductive stage of plant development can lead to a critical setback in the plants development. Only cultivate during the reproductive stage as a rescue method to control weeds. 4). If weeds start getting out of control consider hand labor to remove them. It is up to you to determine if this is cost effective. Herbicide Guide Herbicide guide is found here. Performance Guide is here. |
