Embodiment 1

[0039] Example 1: 25% metazazol-sulfone rimsulfuron-methyl carboxamido wettable powder

[0040] The herbicide composition raw material consumption of the present embodiment is:

[0041] Metraxazone sulfone 20kg, rimsulfuron-methyl carboxamide 5kg, penetrant T12 kg, styrylphenol 10kg, sodium carboxymethyl starch 10kg, starch 8kg, bentonite 35kg.

[0042] The preparation method of the herbicide composition of the present embodiment is:

[0043] Add the above materials together into a conical mixer and mix them evenly, then pulverize them through a jet mill, and then mix them through a conical mixer. The fineness of the mixed materials is 98% and passes through a 600-mesh standard sieve to obtain Wet powder.

Embodiment 2

[0044] Example 2: 50% metazazol-sulfone-carbamidosulfuron-methyl water-dispersible granules

[0045] The herbicide composition raw material consumption of the present embodiment is:

[0046] Metraxazone sulfone 40kg, rimsulfuron-methyl carboxamide 10kg, Tween 18kg, Span 20 8kg, alkylnaphthalene sulfonic acid 7kg, lignin 5kg, polyvinylpyrrolidone 2kg, kaolin 10kg.

[0047] The preparation method of the herbicide composition of the present embodiment is:

[0048] Put the above materials together into the conical mixer and mix them evenly, and then crush them through the jet mill, and then mix the crushed materials through the conical mixer. Knead into a plastic material, and finally put this material into an extrusion granulator to extrude and granulate. After granulation, it is dried and sieved to obtain the corresponding weight percentage rimsulfuron-methyl water-dispersible granules.

Embodiment 3

[0049] Embodiment 3: 36% metazazole sulfone · carboxamido rimsulfuron microemulsion

[0050] The herbicide composition raw material consumption of the present embodiment is:

[0051] Metrazazone sulfone 30kg, rimsulfuron-methyl carboxamide 6kg, calcium dodecylbenzenesulfonate 8kg, methylpentanol 10kg, polyol fatty acid ester 6kg, organic silicon 5kg, toluene 5kg, N, N-di Methylformamide 20kg, water 10kg.

[0052] The preparation method of the herbicide composition of the present embodiment is:

[0053] Put the above materials (except water) into the reactor mixer together, stir for 90 minutes, mix thoroughly, then slowly add water while stirring, and stir for another 30 minutes, after fully mixing, the microemulsion is obtained.

Abstract

The invention discloses a herbicide composition containing metazafen-sulfone and rimsulfuron-methyl carboxamide, which comprises the following active ingredients in parts by weight: 1-80 parts of metazafen-sulfone, 1-50 parts of rimsulfuron-methyl carboxamide . The invention is used for controlling annual broad-leaved weeds, gramineous weeds and sedge weeds in sugarcane fields, mainly preventing and controlling crabgrass, barnyardgrass, foxtail, daughter of a daughter, goosegrass, wild millet, Cyperus rotundum and purslane , cocklebur, black nightshade, clover, red thistle, fennel, datura, weasel petals. The present invention uses the combination of metazafen and rimsulfuron-methyl to enhance the medicinal effect of the herbicide, and the weed control effect on the sugarcane field is better than that of each component used alone, and simultaneously expands the herbicide spectrum. In addition, the herbicide combination has good safety on sugarcane and meets the safety requirements of pesticide formulations.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to a herbicide composition containing metazafen-sulfone and rimsulfuron-carbamide. Background technique [0002] Metraclofenazole, English name: Pyroxasulfone, chemical name: 3-[(5-difluoromethoxy-1-methyl-3-trifluoromethylpyrazol-4-yl)-methylsulfonyl]- 4,5-Dihydro-5,5-dimethyl-1,2-oxazole. Metrafenazole is mainly absorbed through the coleoptile of monocotyledonous plants or hypocotyl of dicotyledonous plants. Root growth stops and then dies; as an electron transport chain inhibitor and uncoupler, it can inhibit plant photosynthesis, interfere with plant protein biosynthesis, affect cell division, and affect membrane biosynthesis and integrity. Widely used in corn, cotton, beans, peanuts, potatoes, rapeseed, garlic, tobacco, sunflower, castor, scallions and other fields to control annual grass weeds and some broad-leaved weeds with small seeds. It has special effects on crabgr...
