A synergist suitable for fomesafen sodium saline

Abstract

The invention discloses a synergistic assistant applicable to a fomesafen sodium salt aqueous solution. The synergistic assistant is mainly prepared from water-soluble surface active agents such as sodium lauroyl sarcosine, polyacrylamide, dodecyl sulfobetaine and brassinolide in a certain proportion. The assistant is good in salt resistance and temperature resistance, has obvious effects for synergy and thickening of fomesafen sodium salt derivatives, and can obviously improve the activity of fomesafen.

Description

technical field [0001] The invention belongs to the field of agricultural surfactants, and relates to a pesticide adjuvant, in particular to an adjuvant suitable for fomesafen sodium saline agent, which can improve the safety of fomesafen sodium saline agent. Background technique [0002] Fomesafen is a high-efficiency and selective herbicide, mainly used for post-emergence weeding in bean fields, and has special effects on controlling broad-leaved weeds. Its principle of action is to destroy photosynthesis through leaf absorption. The agent is also very active in the soil. The main disadvantage of fomesafen is that it will cause some phytotoxicity to soybeans, but it will recover quickly. It is not easy to cause phytotoxicity to soybeans with pre-emergence application after sowing. However, under high temperature, low humidity and drought conditions, the use of fomesafen often causes serious phytotoxicity and even death to soybeans. [0003] The auxiliary agent of the pre...
