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 T12kg, 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, private plate 208kg, 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 Methyl formamide 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 pyrazole sulfone and formamido-pyrazosulfuron-ethyl. The herbicide composition comprises effective components including, by weight, 1-80 parts of pyrazole sulfone and 1-50 parts of formamido-pyrazosulfuron-ethyl. The herbicide composition is used for controlling annual broadleaf weeds, grassy weeds and sedge weeds in sugarcane fields and mainly controlling common crabgrass herbs, barnyard grasses, green bristlegrass herbs, caper euphorbia seeds, goosegrass herbs, wild millets, nutgrasses, purslane herbs, Siberian cocklebur leaves, black nightshade herbs, bidens pilosa, tropic ageratum herbs, piemarkers, hairy datura and galeopsis bifida. The pyrazole sulfone and the formamido-pyrazosulfuron-ethyl are combined in use to enhance themedicinal effect of a herbicide, the weed control effect of the herbicide composition for the sugarcane fields is better than the activity of components individually used, and a weeding spectrum is widened. In addition, the herbicide composition is good in safety for sugarcanes and meets the safety requirements of pesticide preparations.

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...
