Embodiment 1

[0023] 4% atrazine and 6% terbuthine, 6% maleic acid-acrylic acid copolymer as dispersant, 4% pull-off powder BX as dispersant, 3% nonylphenol as wetting agent Polyoxyethylene ether, 3% sodium lauryl sulfate as a wetting agent, 10% ammonium nitrate as a disintegrant, 10% urea as a disintegrant, and 54% cornstarch as an inert filler are thoroughly mixed together After uniformity, use a jet mill for ultrafine pulverization to obtain a 700-mesh fine powder, then knead the resulting fine powder with an appropriate amount of water in a kneader, granulate it through an extrusion granulator, and grind it in a fluidized fluidized bed. Dry at 70°C to obtain atrazine-terbuthine water-dispersible granules.

Embodiment 2

[0025] 14.3% of atrazine and 15.7% of terbuthine, 8% of octylphenol polyoxyethylene ether phosphate as a dispersant, 5% of fatty amide N-methyl taurine sodium salt as a wetting agent, 10% as the sucrose of disintegrating agent, and 31% as the diatomite of inert filler, after 16% as inert filler attapulgite fully mix together, carry out superfine pulverization with jet mill, obtain 600 order fine powders, again The obtained fine powder is kneaded with an appropriate amount of water in a kneader, granulated by an extrusion granulator, and dried in a fluidized fluidized bed at 65°C to obtain atrazine-terbutyline water-dispersible granules agent.

Embodiment 3

[0027] 25% atrazine and 25% terbuthine, 4% NNO as dispersant, 4% pull-off powder BX as dispersant, 4% sodium lauryl sulfate as wetting agent, 4% Ammonium sulfate as disintegrating agent, 2% urea as disintegrating agent and 32% talcum powder as inert filler are fully mixed together, carry out superfine pulverization with jet mill, obtain 800 order fine powders, then the obtained The fine powder is kneaded with an appropriate amount of water in a kneader, granulated by an extrusion granulator, and dried in a fluidized fluidized bed at 50°C to obtain atrazine-terbuthyzine water-dispersible granules.

Abstract

The invention discloses a herbicide composition containing atrazine and terbuthylazine and a preparation method thereof. The composition takes atrazine and terbuthylazine as active ingredients. The herbicide composition disclosed by the invention can effectively prevent and kill grass such as alopecurus aequalis, hairy finger and green bristlegrass in corn fields, and the preventing effect of the composition is much higher than that of atrazine or terbuthylazine alone; in addition, the use of the composition not only can improve medicine effects, but also can reduce medicine dosage, save economic cost, greatly reduce dosage of each active matter, reduce residual of medicine in the environment, delay the generation of resistance in grass and prolong the service life of the medicine; and thus, the herbicide composition has a great ecological and environment-protection significance.

Description

technical field [0001] The invention relates to a pesticide and a preparation method thereof, in particular to a herbicide and a preparation method thereof, and belongs to the technical field of pesticides. Background technique [0002] Atrazine, English common name: atrazine, chemical name: 2-chloro-4-diethylamino-6-isopropylamino-1,3,5-triazine, also known as atrazine, Aatrex, Primatola. The appearance of atrazine is white powder, easily soluble in organic solvents, relatively stable in slightly acidic or slightly alkaline medium, but at higher temperature, alkali or inorganic acid can make it hydrolyze. Atrazine is a selective systemic conduction pre-emergence and post-emergence herbicide. It is mainly absorbed by roots, with little absorption by stems and leaves. kill weeds. Atrazine is decomposed into non-toxic substances by corn ketolase in resistant crops such as corn, so it is safe for crops. Currently, atrazine is mainly used in the two dosage forms of suspension...
