Problems solved by technology

Disadvantages: First, the pH value is greatly affected by soil type and organic matter content. If the soil is too sticky, the organic matter content is too high, or the pH value does not meet a certain chemical agent, it is not suitable to use soil treatment; second, some herbicides such as metrizone , 2,4-D butyl ester, etc. are prone to phytotoxicity due to leaching of chemicals in sandy soil and low-lying land; third, it is greatly affected by meteorological conditions, especially spring drought, strong wind and abnormal low or high temperature will affect the weeding effect
Disadvantages: First, the weeding effect is not good in the case of drought and little rain, lo...

Abstract

The invention discloses a wheat field synergistic herbicidal composition containing isoproturon. The composition is composed of N-(5-tert-butyl-1,3,4-thiadiazole-2-yl)-N'-(2,6-difluoropyridine-4-yl)-N,4-dimethyl-1,2,3-thiadiazole-5-formamidine (TDCA-10) and isoproturon, which are effective components, and acceptable auxiliary components in pesticides, wherein an allowable weight ratio of the TDCA-10 to the isoproturon in the herbicidal composition of the invention is 50:1 to 1:50, preferably 10:1-1:10. Laboratory pot experiments and field efficacy experiments show that the combination of the two effective components can form a synergistic effect, can expand a herbicidal spectrum, has no antagonistic action and is improved in safety for crops.
