Embodiment 1

[0031] Embodiment 1: 36% amiloride tribesulfuron-methyl oil suspension concentrate

[0032] The components of the pesticide composition are: amclopyralid 10%, tribenuron-methyl 26%, phenethylphenol polyoxyethylene ether 5%, sodium lignosulfonate 8%, epoxidized soybean oil 5%, organic bentonite 5%, methyl oleate to 100%.

[0033] After amiloride is adsorbed and mixed with the filler, other above-mentioned materials (except organic bentonite) are added to the reactor mixer together, stirred evenly, and the materials are injected into a multi-stage sand mill for grinding. The fineness of the ground materials is After 98% pass through 1-5um, the material is discharged, and the material is put into a high-shear emulsification kettle together with the pre-dissolved organic bentonite. After emulsification, a 36% amclopyral-tribesulfuron oil suspension can be made.

[0034] Tribesulfuron-methyl in this example can be replaced by bensulfuron-methyl, thifensulfuron-methyl, bispyribac o...

Embodiment 2

[0035] Example 2: 40% amiloride-bensulfuron-methyl suspension concentrate

[0036]The components of the pesticide composition are: 20% of amclopyralid, 20% of bensulfuron-methyl, 5% of phenethylphenol polyoxyethylene ether, 8% of sodium lignosulfonate, 5% of ethylene glycol, silicon Magnesium aluminum acid 2%, defoamer 0.5%, preservative 0.1%, xanthan gum 0.1%, water to 100%.

[0037] After amiloride is adsorbed and mixed with the filler, other above-mentioned materials (except xanthan gum) are added to the reactor mixer together, stirred evenly, and the materials are injected into a multi-stage sand mill for grinding, and the ground materials are fine The material is discharged after passing through 1-5um with a density of 98%. The material is put into a high-shear emulsification kettle together with the pre-dissolved xanthan gum. After emulsification, it can be made into 40% amiloride-bensulfuron-methyl suspension concentrate .

[0038] The bensulfuron-methyl in this examp...

Embodiment 3

[0039] Example 3: 42% amiloride · bispyribac wettable powder

[0040] The components of the pesticide composition are: 21% of amiloride, 21% of bispyribac, 3% of sodium butylnaphthalene sulfonate, 5% of calcium lignosulfonate, 5% of white carbon black, and up to 100% of kaolin .

[0041] After amiloride is adsorbed and mixed with the filler, it is added to the conical mixer together with other above-mentioned materials and mixed evenly, and then pulverized by the jet mill, and the pulverized material is then mixed by the conical mixer, and the fineness of the mixed material is 98% passed through a 325-mesh standard sieve to obtain a 42% amiloride-bispyribac wettable powder.

[0042] The bispyribac-methyl in this example can be replaced by bensulfuron-methyl, thifensulfuron-methyl, tribenuron-methyl or thiazosulfuron-methyl, and a new example is formed according to the same conditions and formula ratios.

Abstract

The present invention discloses a pesticide composition containing picloram or picloram salt, and application of the pesticide composition containing the picloram or the picloram salt. The pesticide composition comprises effective ingredients of a component I and a composition II, wherein the component I is the picloram or the picloram salt; the composition II comprises tribenuron-methyl, bensulfuron methyl, thifensulfuron methyl, bispyribac-sodium or thiencarbazone-methyl; the mass ratio of the component I to the composition II is (1:50)-(25:1). The present invention also discloses a preparation prepared from the pesticide composition and suitable for being used in agriculture, and application of the preparation in preventing and killing of broadleaf weeds in wheat fields. The pesticide composition containing the picloram or the picloram salt has an obvious synergistic effect, reduces use amount of pesticides, the use times of the pesticides, the use cost of the pesticides, and adverse effects of the pesticides on ecological environments, enlarges weeding range, can solve a problem of various broadleaf weeds by one-time pesticide applying, makes up for defects and limitation caused by use of single agents, prolongs the service life of agents, and has important significance on comprehensive treatment of weed resistance; and the pesticide composition is fast in effect acting, long in effect period, and low in use cost, and has wide development and popularization prospects.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to a pesticide composition containing amiloride or a salt thereof for controlling broad-leaved weeds in wheat fields. Background technique [0002] In recent years, due to changes in farming and cultivation methods, the weeds and weeds in farmland have changed significantly. At present, the grass phase of broad-leaved weeds in wheat fields has been replaced by the main hazards of shepherd's purse and vetch, to pig's weed, cow chickweed and wild geranium. The chemical herbicides used to control broad-leaved weeds in wheat fields are mainly sulfonylurea herbicides such as tribenuron-methyl and bensulfuron-methyl. Long-term single and continuous use has led to high levels of weed resistance to a single agent of this type of herbicide. sex. The rapid occurrence and spread of weed resistance has led to increasing pesticide costs for farmers, posing a serious threat to the safe produ...
