Problems solved by technology

[0010] At present, herbicides in soybean fields are limited by the safety of crops, and their herbicidal spectrum is also limited. Using a single herbicide alone cannot completely and effectively control the occurrence of weeds in soybean fields. Too long effective period, excessive dosage or uneven application will easily cause residual toxicity to current crops or subsequent crops
In the existing field of pesticide formulation production, there is no information about mixing bentazone, brassinolide compounds and triazine herbicides to make pesticide active ingredients, and seaweed polysaccharide, pectic acid, sulfosuccinic acid fatty acid Alcohol and propylene glycol butyl ether are mixed to make pesticide synergistic adjuvant, combined to prepare herbicide report

Abstract

The invention discloses a triazine weeding composition containing brassinolide compounds. The composition comprises an active ingredient and a synergistic aid. The active ingredients comprise bentazone, asulam and a triazine herbicide. The synergist is prepared from the brassinolide compound, algal polysaccharides, pectic acid and sulfosuccinic acid fatty alcohol. The composition has an extremelygood synergistic effect within a certain ratio range. Compared with a single agent, the mixed composition has the advantages that the weeding effect is obviously improved, so that the use dosage is reduced, the pesticide cost of farmers is reduced, and meanwhile, the influence degree on the environment is reduced. The composition has a wide weeding spectrum, can prevent and remove broadleaf weedsand other weeds in a soybean field, and has a very good synergistic effect. Compared with a single preparation, the composition has an obvious synergistic effect, is high in weeding speed, delays thedrug resistance of weeds, and has very good safety to a soybean field.

Description

technical field [0001] The invention relates to the technical field of compound herbicides, in particular to a triazine herbicide composition containing brassinolide compounds. Background technique [0002] my country has a long history of planting soybeans, and the weeds that harm soybean fields mainly include annual grass weeds, such as: barnyardgrass, foxtail, crabgrass, wild oats, goosegrass, etc.; annual broad-leaved weeds, such as: Chenopodium (ashweed) , cocklebur, purslane, black nightshade (black star), iron amaranth, Polygonum, pigskin, commelina (orchid), chickweed, etc.; Vegetables, small thistle (thorn vegetable), bermudagrass, large thistle (big thorn vegetable), reed, dawanhua, etc. [0003] Chemical weeding is one of the main means of controlling weeds in agriculture. In recent years, due to the large-scale single use of some herbicide varieties, many weeds have developed resistance. At the same time, when weeds occur, the grass phase is complex, grass weeds...
