Abstract

The invention discloses a synergistic weeding pesticide composition. The composition is composed of 2-(6-fluoro-2-pyridyl oxo)-N-(4-fluorophenyl)-N-(1-methyl ethyl) thioacetamide (TMA-5) and haloxyfop-R-methyl serving as active ingredients as well as acceptable auxiliary ingredients in pesticides, wherein the weight ratio of the TMA-5 to haloxyfop-R-methyl is 20:1 to 1:2. The two active ingredients are combined to form a synergistic effect, and the composition is capable of widening the weed control spectrum, does not have antagonism and can improve the crop safety. The synergistic weeding pesticide composition is capable of effectively controlling annual gramineous weeds and further inhibiting partial perennial gramineous weeds, is particularly applicable to weed control in soybean fields, can obviously improve the weeding effect, and is safe to commercial crops such as soybeans.

Description

technical field [0001] The invention relates to a herbicidal pesticide composition, which is especially used for weeding in soybean, cotton, peanut, potato, rapeseed, watermelon, hemp, vegetables and other farmlands and non-cultivated lands. Background technique [0002] High-efficiency fluroxyfop, another name in Chinese is high-efficiency Gaicaoneng, and its full name in English is (R)-Methyl 2-[4-[[3-Chloro-5-(trifluoro-methyl)-2-pyridinyl]oxy]phenoxy]propanoic acid, English abbreviation Haloxyfop-methyl. The Chinese chemical name of high-efficiency fluorifop-pyl is (R)-2-[4-(5-trifluoromethyl-3-chloro-pyridine-2-oxyl)phenoxy]propionic acid methyl ester, molecular formula C 16 h 13 CIF 3 NO 4 , molecular weight 375.73, CAS No. 69806-40-2, and its structural formula is shown in Formula 1. The melting point of pure high-efficiency flurifop-pamide technical substance is 55-57°C, and the boiling point is 390.8°C (1 atm). Under neutral and 25°C conditions, it is easily s...
