Embodiment 1

[0022] Formulation example 1: 68% fluramid propargyl · methazepam · clethodim water dispersible granules.

[0023] Flurafen propargyl 8%, methazepam 25%, clethodim 35%, sodium lauryl sulfate 2%, alkylphenol polyoxyethylene ether sulfate 2%, urea 3%, sodium bicarbonate 3 %, bentonite makes up 100%. Mix the above-mentioned effective ingredients, additives and carriers evenly, pulverize them with an ultrafine jet mill, knead them, and then add them to a fluidized bed granulation dryer for granulation, drying, and sieving to obtain 68% propyne Fluoroxam · Methazepam · Clethodone Water Dispersible Granules.

Embodiment 2

[0024] Formulation example 2: 55% fluramid propargyl · methazepam · clethodim wettable powder.

[0025] Flumecil propargyl 5%, methazepam 20%, clethodim 30%, tributyl phosphate 4%, sodium lauryl sulfate 4%, sodium chloride 3%, wood calcium 4%, bentonite supplement 100% . The above-mentioned active ingredients, auxiliary agents and carriers are mixed, mechanically pulverized and then air-flow pulverized, and mixed evenly to prepare 55% fluramid-methazopyr-clethodim wettable powder.

Embodiment 1

[0026] Biological Assay Example 1: Example of Indoor Bioactivity Assay.

[0027] Drugs to be tested: 96% of the original drug of flutrazone propargyl, 97% of the original drug of imazethapyr and 95% of the original drug of clethodim.

[0028] Targets for testing: Li (Chenopodium album), Setaria uiridis (Setaria uiridis)

[0029] Medication configuration design: single dose of flufenazol propargyl is prepared as 3, 6, 12 g.a.i. / ha solution for standby; single dose of memazazole is prepared as 10, 20, 40 g.a.i. / ha solution for standby; single dose of clethodim Configured as 15, 30, 60g.a.i. / ha solution for standby; propargyl flufenamide, methazepam and clethodim mixture configured as 3+10+15, 3+10+30, 3+10+60, 3+10+15, 3+20+30, 3+20+60, 3+40+15, 3+40+30, 3+40+60, 6+10+15, 6+10+30, 6+ 10+60, 6+20+15, 6+20+30, 6+20+60, 6+40+15, 6+40+30, 6+40+60, 12+10+15, 12+10+ 30, 12+10+60, 12+20+15, 12+20+30, 12+20+60, 12+40+15, 12+40+30, 12+40+60 g.a.i. / ha solution for use.

Abstract

The invention relates to a weeding composition for peanut fields. The weeding composition comprises the following effective components in parts by weight: 1-20 parts of flumioxazin, 1-20 parts of imazapic and 1-20 parts of clethodim. The weeding composition disclosed by the invention has the function of synergistic interaction and is applied to preventing and weeding annual weeds in the peanut fields, compared with the effect by separately using single doses, the effect is obviously better, and the spectrum of weed control is extended; besides, the usage amount of agricultural chemicals is reduced, environmental pollution is alleviated, and the production of the drug resistance to weeds is suspended.

Description

technical field [0001] The invention relates to a pesticide herbicide composition and its application field, in particular to a herbicide composition with flutrafenyl, imazethapyr and clethodim as active ingredients, which is used for controlling annual weeds in peanut fields. Background technique [0002] Chemical herbicide is one of the main means of controlling weeds in agriculture. When weeds occur, the grass phase is complex, a variety of weeds are mixed, and the use of a single species of herbicide cannot solve the weeds in the farmland, which will show some defects and limitations. The mixing of different types of compounds has the advantages of improving the actual effect, expanding the weeding spectrum, and saving time and labor. [0003] Propyrphyrin is an enzyme that inhibits protoporphyrinogen oxidase (PPO), which is very important in plant chlorophyll synthesis. After treatment, protoporphyrin accumulates in the body of sensitive plants, resulting in photosensi...
