Abstract

The invention discloses a garden herbicide synergistic combination which contains two effective constituents, namely imazapic and glyphosate isopropylamine, wherein the weight ratio of the imazapic to the glyphosate isopropylamine is 1:(0.8-13). The garden herbicide synergistic combination can be developed into more general water aqua and other general dosage forms conveniently applied to garden plants. The combination with the two constituents has a synergistic interaction effect, so that the weed removal spectrum can be expanded, the prevention and removal effect is enhanced, and the pesticide hazard to garden trees is reduced. A test result shows that cuscuta chinensis lam, catharanthus roseus, cuscuta reflexa, cuscuta australis and the like can be effectively prevented and removed. The garden herbicide synergistic combination has the characteristics of high obvious dispersion performance, wide weed removal spectrum, high durability, convenience in use, safety against garden trees, safety to human and environment and the like.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to a garden herbicide synergistic composition. Background technique [0002] There are many kinds of landscaping trees, mainly mango, almond, sheep's hoof, laurel, banyan, mango, bougainvillea, crape myrtle, magnolia, kapok, lychee, longan, yellow plum, Fujian tea, fig, palm, wood pineapple etc., are closely related to urban construction and people's life. Cuscuta has strong adaptability, rapid reproduction, and great harm. It is suitable for the high-temperature and high-humidity climate environment in Guangxi. It occurs on various garden trees, and the harm has become more serious in recent years. According to the survey, the incidence rate of hedgerows in general garden trees is about 11.5%, moderately 15-20%, and seriously over 35%. The coverage rate is generally 5-10%, mediumly 20-30%, and seriously 40-100%. The harm of dodder is mainly to establish a parasitic relationshi...
