Embodiment 1

[0047] 51.5% trifluoromethylsulfuron-acetochlor (3:100), dispersible oil suspension

[0048] Pump 395.5 grams of methyl oleate into the shear tank, pump 45 grams of MF, 22 grams of osmotic T, 5 grams of defoamer, and 5 grams of formaldehyde into the shear tank, and then add 15 grams of trifluoromethanesulfonate while stirring. Long, 500 grams of acetochlor, 2.5 grams of xanthan gum, and 10 grams of bentonite were put into the shear tank in order, and the materials were mixed evenly by shearing for 30 minutes. The material is ball milled, the temperature of the ball mill is controlled below 40 degrees, and the fineness of the discharge material passes through a 325 mesh sieve to obtain a 51.5% acetochlor dispersible oil suspension herbicidal composition.

Embodiment 2

[0050] 21% trifluoromethylsulfuron-alachlor (1:20), dispersible oil suspension

[0051] Pump 704.5 grams of methyl oleate into the shear tank, pump 45 grams of MF, 18 grams of NNO, 5 grams of defoamer, and 5 grams of formaldehyde into the shear tank, and then add 10 grams of trifluoromethylsulfuron while stirring , 200 grams of alachlor, 2.5 grams of xanthan gum, and 10 grams of magnesium aluminum silicate are put into the shear tank in order, and the materials are mixed evenly by shearing for 30 minutes. The material is ball milled, the temperature of the ball mill is controlled below 40 degrees, and the fineness of the discharge material passes through a 325-mesh sieve to obtain a 21% triflumesulfuron-alachlor dispersible oil suspension herbicidal composition.

Embodiment 3

[0053] 70.5% trifluoromethylsulfuron-metolachlor (1:140), microcapsule powder

[0054] With 25 grams of DMF, 5 grams of trifluoromethylsulfuron-methyl is completely dissolved and pumped into the shear tank, 700 grams of metolachlor, 30 grams of phenylphenol polyoxyethylene polyoxypropylene ether and its sulfate (or phosphate ester) , 30 grams of calcium dodecylbenzenesulfonate, 180 grams of urea-formaldehyde resin prepolymer, 3 grams of defoamer, after shearing, slowly add 180 grams of initiator while stirring, slowly stir at 60 °C for half an hour, and then pass Freeze dry under vacuum. A 70.5% triflumesulfuron-metolachlor microcapsule powder herbicidal composition can be obtained.

Abstract

The invention belongs to the technical field of pesticide preparations, and particularly relates to a weeding composition containing tritosulfuron pestanal active components. The weeding composition comprises a component A and a component B which serve as the active components, wherein the component A is tritosulfuron pestanal, the component B is one or more of compounds including acetochlor, alachlor, metolachlor, dimethenamid, efficient dimethenamid, propisochlor, propachlor, ethachlor, diphenamide, ethaprochlor, flufenacet, allidochlor, prynachlor, nicosulfuron, rimsulfuron, thifensulfuron, atrazine, cyanazine, simazine, simetryn, ametryn, terbutryn, terbuthylazine, dimethyl tetrachloro, 2, 4-D butyl ester, 2, 4-D isooctyl ester, fluroxypyr, dichloro pyridine acid and fluroxypyr-mepthyl. The weeding composition can greatly improve preventing and removing effects of single doses, enlarges weeding spectrum, reduces dosage per mu (Chinese acre) and is very safe to crops.

Description

technical field [0001] The invention belongs to the technical field of pesticide preparations, and in particular relates to a herbicidal composition containing an active ingredient of triflumesulfuron-methyl and an application thereof. Background technique [0002] As one of the three major food crops in my country, the planting area and output of corn have gradually increased in recent years. The development of corn production plays an important role in ensuring the safety of my country's food production, increasing farmers' income, and developing the economy. However, due to the high temperature and high humidity during the growth period of corn (summer corn), the occurrence of weeds in the field is large, which poses a serious hazard to corn production. Weeds in cornfields compete with corn for nutrients, water, light and living space, causing the corn to become thin and yellow at the slightest, and completely covering the corn seedlings and inhibiting its growth, resulti...
