What about the drug damage caused by beans? Is there any way to save it? Netizens are also asked to help introduce the performance and prevention measures of drug damage caused by beans in the farming network, which are listed below for netizens' reference. Symptoms of beans damaged by herbicides: after accidentally spraying herbicides, the old leaves of beans are dry at first, and the stems are still green. With the growth of beans, the new leaves are deformed and the leaves are wrinkled and uneven. If the bean is in the podding stage, there will be falling flowers. The plant growth is poor, which seriously affects the yield. Remedial measures for drug damage of beans: method 1. Rinse with clean water: the period for farmers to spray herbicides is generally 7-10 days. During this period, the stems and leaves of beans should be frequently sprayed with water to reduce the pesticide residues on the stems and leaves of beans. Method 2. Topdressing in time: ammonium bicarbonate or urea is the main topdressing, and it can also be properly combined with some phosphorus and potassium fertilizer. The amount of topdressing should be determined according to the severity of drug damage and the growth of beans. Method 3. Adequate watering: timely watering after topdressing in order to promote the fertilizer effect as soon as possible and reduce the relative concentration of harmful substances in beans. Method 4. Foliar spraying of plant growth regulator and foliar fertilizer: the mixed spraying effect of brassine 7500 times liquid and foliar fertilizer is better. According to the degree of drug damage, spray once every 10-15 days, can be sprayed for 1-3 times. Click to get more bean planting techniques click to get more vegetable planting techniques
