Embodiment 1

[0019] Example 1: The mass ratio of diflufenamide to propachlor is 10-60:5, the total mass of diflufenamide and propachlor in the herbicide is 15-70% by mass, and the following substances All are weight percentages, take 60% of diflufenamide, 5% of propachlor, 8% of sodium lignosulfonate, and 3% of sodium methylenebisturidesulfonate, and then mix them uniformly, and continuously add kaolin, Make the mass ratio of the whole mixture reach 100%, and follow the general steps to form a wettable powder mixed herbicide with a mixed mass ratio of diflufenamide and propachlor with a mass ratio of 65%.

Embodiment 2

[0020] Example 2: The mass ratio of diflufenamide to propachlor is 40-60:5-10, the total mass of diflufenamide and propachlor in the herbicide is 45-70% by mass, The following substances are all percentages by weight, take 50% of diflufenamide, 10% of propachlor, 5% of alkylphenol polyoxyethylene ether, and 8% of castor oil polyoxyethylene ether, and then mix them evenly and add them continuously water to make the mass ratio of the whole mixture reach 100%, and follow the general steps to form a water-emulsion mixed herbicide whose mixed mass ratio of diflufenamide and propachlor is 60%.

Embodiment 3

[0021] Example 3: The mass ratio of diflufenamide to propachlor is 30-50:10-20, the total mass of diflufenamide and propachlor in the herbicide is 40-70% by mass, The following substances are all percentages by weight. Take diflufenamide 40%, propachlor 5%, sodium lignosulfonate 3%, lauryl sulfate 5%, and then mix evenly, and continuously add kaolin, Make the mass ratio of the whole mixture reach 100%, and follow the general steps to form a water-dispersible granular mixed herbicide with a mixed mass ratio of diflufenamide and promethachlor of 45%.

Abstract

The invention discloses a diflufenican and propisochlor mixed herbicide and a preparation method thereof. The diflufenican and propisochlor mixed herbicide comprises diflufenican and propisochlor, the mixed herbicide takes diflufenican and propisochlor as main drug effect components, the mass ratio of diflufenican to propisochlor is 1-60:1-30, and the total mass of diflufenican and propisochlor accounts for 5-70% of that of the herbicide. According to the invention, diflufenican and propisochlor are mixed according to different ratios, obvious synergy or addition effect can be provided, the weeding effect is increased, so that corn, soybean and wheat field weeds can be thoroughly killed, so that one-time application of the herbicide is realized, time is saved, labor is saved, and peasant burden is mitigated, and the herbicide has the advantages of high weeding activity, wide weeding spectrum, long persistent period and high security.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a mixed herbicide of diflufenamide and propachlor and a preparation method thereof. Background technique [0002] Diflufenican, chemical name: N-(2,4-difluorophenyl)-2-[(3-trifluoromethyl)phenoxy]-3-pyridineanilide. The drug is a carotenoid biosynthesis inhibitor. The content of carotenoids in the weed plants that absorb the drug decreases, resulting in the destruction of chlorophyll and cell rupture. The weeds appear as discolored or white young shoots, and finally the plants wilt and die. Mainly used in corn, soybean and wheat fields to control a variety of annual grass weeds and some broad-leaved weeds. Especially for the removal of pig's calamity and mother-in-law. [0003] Propisochlor is an amide systemic selective pre-emergent herbicide. It is suitable for dryland crops such as soybean, corn, sunflower, potato, sugar beet and pea to control annual gramineous weeds su...
