Abstract:
In order to study the effects of new biological adjuvants on water aqua, emulsifiable concentrate and suspending agent of herbicides commonly used in soybean and maize fields in China, field experiments were conducted with nonionic surfactants, methyl esterified vegetable oils and organosilicon adjuvants as controls.The effects of different herbicides with new biological adjuvants on the control of grassy weeds and broad-leaved weeds were investigated and evaluated. The results showed that the new biological adjuvants could improve the control effect of herbicide water aqua on weeds by 22.82%-31.62%, fresh quality by 21.97%-32.30%, control effect of herbicide emulsifiable concentrate by 19.31%-31.27%, fresh quality by 20.71%-32.13%, control effect of herbicide suspending agent by 21.14%-36.11%, and fresh quality by 21.58%-38.17%. The synergistic effect of new biological adjuvants on suspending agent was the most obvious, followed by water aqua and emulsifiable concentrate. New biological adjuvants could significantly improve the biological activity of herbicide water aqua, emulsifiable concentrate and suspending agent. Its synergistic effect is better than methyl esterified vegetable oils ,organosilicon adjuvants and nonionic surfactants, and it is safe for crops.
