Embodiment 1

[0026] Embodiment 1: wettable powder

[0027] A new compound herbicide containing polyglutamic acid, the formula is composed of the following components in weight percentage: 0.5% polyglutamic acid, 8% pretilachlor, 10% butachlor, 15% bensulfuron-methyl, emulsified Agent sodium lauryl sulfate 2%, dispersant calcium lignosulfonate 8%, filler white carbon black 18%, filler kaolin to make up to 100%.

[0028] Preparation method: according to the proportion of the formula in the example, add the active ingredients polyglutamic acid, pretilachlor, butachlor and bensulfuron-methyl to the carrier, and add emulsifier and other functional auxiliaries to it, mix, and pass through the airflow Mix after pulverization, and pass through a 325-mesh standard sieve after mixing to obtain a wettable powder.

Embodiment 2

[0029] Embodiment 2: water dispersible granules

[0030] A new compound herbicide containing polyglutamic acid, the formula is composed of the following components in weight percentage: polyglutamic acid 1%, pretilachlor 10%, butachlor 15%, bensulfuron-methyl 20%, dispersed 5% sodium alkylnaphthalene sulfonate, 7% sodium lignosulfonate dispersant, 2% sodium lauryl sulfate emulsifier, 5% urea (disintegrating agent), light calcium carbonate supplemented to 100%.

[0031] Preparation method: According to the ratio of the formula in the example, the active ingredients polyglutamic acid, pretilachlor, butachlor and bensulfuron-methyl are added to the carrier, and surfactants and other functional auxiliaries are added therein, mixed and passed through Add 10-25% water after jet crushing, then knead, granulate, dry, and sieve to obtain water-dispersible granules; or spray the crushed powder with water, granulate, and dry in a boiling granulator , and then screened to obtain the prod...

Embodiment 3

[0032] Embodiment 3: oil suspension

[0033] A new compound herbicide containing polyglutamic acid, the formula is composed of the following components in weight percentage: 1% polyglutamic acid, 15% pretilachlor, 15% butachlor, 15% bensulfuron-methyl, emulsified Agent agricultural milk BY-125 7%, dispersant polycarboxylate 8%, thickener organic bentonite 1.6%; oil to make up to 100%.

[0034] Preparation method: according to the proportion of the formula in the example, the active ingredients polyglutamic acid, pretilachlor, butachlor, and bensulfuron-methyl, surfactants and other functional additives are placed in the reaction kettle in sequence, and the oil is mixed evenly. After high-speed shearing, wet sanding, and finally homogeneous filtration, the product is obtained.

Abstract

The present invention discloses a polyglutamic acid-containing composite weeding agent, which comprises, by mass, 15-55% of an active component and 45-85% of an auxiliary material, wherein the activecomponent is prepared by compounding polyglutamic acid, pretilachlor, butachlor and bensulfuron-methyl, and the auxiliary material comprises a combination comprising one or a plurality of materials selected from a solvent, a dispersing agent, an emulsifier, a thickener and a filler. According to the present invention, the composite weeding agent can exhibit obvious synergistic effect, has the prevention and control effect obviously superior to the activity generated by the single use of various components, has advantages of reduced use frequency, reduced consumption, reduced use cost and reduced damage on the ecological environment, can effectively prevent and remove weeds in rice fields and corn fields, has obvious effects on broadleaf weeds and Poaceae weeds, has high safety to crops, and further can effectively improve the fertilizer utilization rate, enhance the crop quality and increase the crop yield.

Description

technical field [0001] The invention belongs to the technical field of compound pesticides, in particular to a compound herbicide containing polyglutamic acid. Background technique [0002] Weeds can seriously threaten crop yield and cause huge economic losses to agricultural production. Compared with manual weeding, herbicides have the advantages of economy, speed, and high efficiency, which provide an important guarantee for high and stable agricultural yields. However, in recent years, the long-term, single, and extensive use of herbicides has led to an increase in resistant weed individuals and populations year by year, reducing the control effect of herbicides and increasing the cost of weed control; at the same time, the increase in herbicide dosage is also easy Cause crop phytotoxicity risk and environmental pollution. At present, the problem of weed resistance has become one of the important problems threatening the production of food crops. Therefore, it is of gr...
