Embodiment 1

[0036] The preparation of embodiment 1 wheat field herbicidal composition wettable powder

[0037] Take 24% of fluclopyridine, 10% of tribenuron-methyl, 3% of pull open powder, 12% of NNO (sodium methylene bis-naphthalene sulfonate), 6% of talcum powder, and make up to 100% of kaolin, mix well, and pass through the air flow After pulverization, 34% haclopyridin·tribesulfuron-methyl wettable powder is obtained.

Embodiment 2

[0038] The preparation of embodiment 2 wheat field herbicidal composition wettable powder

[0039] Take 15% of fluclopyridine, 75% of thifensulfuron-methyl, 3% of sodium lauryl sulfate, 5% of calcium lignosulfonate, 35% of attapulgite, and light calcium carbonate to make up to 100%, mix well, After being pulverized by airflow, 19% wettable powder of haclopyridin and thifensulfuron-methyl was obtained.

Embodiment 3

[0040] The preparation of embodiment 3 wheat field herbicide composition suspension concentrate

[0041] Take fluclopyridine 18%, bensulfuron-methyl 15%, sodium lignosulfonate 4%, sodium dodecylsulfonate 2%, xanthan gum 0.2%, glycerol 3%, add water to 100% , mixed, sheared evenly, and ground until D(90) was less than 5 μm to obtain a 33% haclopyridyl bensulfuron-methyl suspension concentrate.

Abstract

The invention relates to the field of pesticide preparations, and particularly relates to a wheat field weeding composition and a preparation of the wheat field weeding composition. The wheat field weeding composition comprises halauxifen-methyl and active components, wherein the active components are selected from clopyralid, 2-methyl-4-chlorine sodium, carfentrazone, dicamba, tribenuron-methyl, bensulfuron methyl or thifensulfuron methyl. The wheat field weeding composition is mixed to use, and has an obvious synergistic effect. According to the wheat field weeding composition and the preparation of the wheat field weeding composition, the overall control effect of wheat field weeds can be improved, the active components do not have antagonistic action, and the dosage is reduced.

Description

technical field [0001] The invention relates to the field of pesticide preparations, in particular to a wheat field herbicidal composition and its preparation. Background technique [0002] Wheat is one of the main food crops in northern my country. It is rich in starch, protein, fat, minerals, calcium, iron, thiamine, riboflavin, niacin and vitamin A. It is the second largest grain in the world. Crops, my country's perennial planting area is more than 30 million hectares, second only to rice planting area. Most of the wheat fields in my country have been affected by weeds to varying degrees. The area of ​​weed damage accounts for more than 55% of the wheat planting area, of which the severely damaged area accounts for 28%, and the loss of yield accounts for 15% of the total wheat output. Therefore, the proportion of herbicides used in domestic wheat fields is almost 100%. [0003] Haclopyridine can be used as a picolinate herbicide for the control of post-emergence broadle...
