Soybean is a parasitic weed on soybean, also known as the rootless vine. After soybean seeding and emergence, the seeds of Cuscuta in the soil also began to germinate. After the young stems protruded from the soil surface, the nutrients of the soybean plants were absorbed, and the pods of soybeans were reduced. In severe cases, the whole soybeans withered, with a large yield and quality of soybeans. Impact. In the past, we used acetochlor, lasso, and dilamine in the prevention and control of dodders before and after seedlings. Although the effects were there, they were not ideal. In recent years, farmers in the soybean producing areas have used glyphosate to control the dodder, and have achieved good results, and the control effect is generally above 85%.
The principle of using glyphosate to control dodder is mainly to use the difference of glyphosate resistance between parasitic and host plants, that is, soybean has strong resistance to glyphosate, and can tolerate a certain range of liquid medicine. Concentration, while the resistance of dodder is very poor. The method is: shortly after the emergence of the dodder, in the early stage of the soybean damage, when the center of the dodder is found, spray it on the soybean plant at the disease center with a 400% dilution of 10% glyphosate, and spray evenly, do not leak. 10 to 15 days after spraying, the dodder was killed in large numbers. However, after 3 to 4 days after the drug, the young leaves of soybean began to yellow, which showed slight phytotoxicity, but had no significant effect on their growth and development. After about 7 days, the rate of yellowing plants stopped expanding, and all young leaves changed about 10 days later. Green, return to normal growth.
