Glyphosate is a good helper for controlling soybean dodder

Soybean dodder is a parasitic weed on soybeans, also known as rootless. Usually, after the emergence of soybeans, the seeds of Cuscuta in the soil begin to germinate. After the young stems extend out of the soil surface, the nutrients of the soybean plants are absorbed, and the pods of the soybeans are reduced. In severe cases, the whole soybeans are withered, which seriously affects the yield and quality of the soybeans. Before we were in pre-emergence post-emergence use of acetochlor, cable, Butralin and other pesticides to prevent and treat Dodder, although the effect is there, but not ideal. In recent years, the use of glyphosate to control dodder has achieved good results. The control effect is usually above 85%. Learn more with Xiaobian:
The use of glyphosate to control dodder is mainly due to the difference in glyphosate resistance between the parasitic and host plants, that is, soybean has strong resistance to glyphosate and can tolerate the concentration of the drug in a certain measurement range. However, the resistance of dodder is very poor. The method is to harm the early stage of soybeans and the occurrence period of the field in the field shortly after emergence of the dodder. When it is found that there is a dodder seeding center, the pesticide manufacturer recommends spraying the soybean plant with the 400% dilution of 10% glyphosate on the soybean center of the disease center. The spray should be uniform and not leaking. 10-15 days after spraying, the dodder was killed in large numbers. However, 3-4 days after the drug, the young leaves of soybean began to yellow, which showed slight phytotoxicity, but had no significant effect on its growth and development. After about 7 days, the rate of yellowing plants stopped expanding, and all young leaves changed about 10 days. Green, return to normal growth.

In addition, the China Pesticide Network reminds everyone that since Dodder is constantly occurring in the field, it should be inspected once or twice in the first two weeks after the first use of the drug to achieve the purpose of thorough prevention.
