Glyphosate is effective against soybean reed

Soybean Cuscuta is a parasitic weed on soybeans, also known as rootless. After sowing soybean seedlings, the seeds of the seedlings in the soil begin to germinate. After the young stems extend out of the soil surface, they absorb the nutrients of the soybean plants, and the flowering and pods of the soybeans are reduced. When the soybeans are severe, the whole plant of the soybeans withers, and the yield and quality of the soybean are great. Impact. In the past, we controlled the use of acetochlor, lansoline, and ditergylamine in the pre-emergence and post-emergence treatments. Although there are effects, they are not ideal. In recent years, farmers in soybean producing areas have used glyphosate to prevent and control dodder and have achieved relatively good results. Control efficiency is generally above 85%.

The principle of using glyphosate to control dodder seedlings is mainly to use the difference in resistance of glyphosate between the two plants, parasitic and host, that is, soybean has stronger resistance to glyphosate and can tolerate a certain range of liquid chemicals. Concentration, while the resistance of the dodder is poor. The method is: Soon after the emergence of dodder, harm the early stage of soybean, found that there is a center of occurrence of dodder seed, spray with 10% glyphosate 400-fold dilution in the center of the disease on soybean plants, spraying should be uniform, do not miss the spray. 10-15 days after spraying, there was a large number of dodder deaths. But 3-4 days after the drug, the young leaves of the soybean began to yellow, that is, a slight injury performance, but no significant impact on its growth and development, the rate of yellowing plants stopped expanding after about 7 days, and all the young leaves changed in about 10 days. Green, restore normal growth.
