Embodiment 1

[0080] Example 1 Combined Action Effect of Wheat Field Herbicide Composition on Weeds in Wheat Field

[0081] Adopt co-toxicity coefficient method to evaluate the synergistic effect of the wheat field herbicidal composition provided by the present invention: find regression with the natural logarithm of medicament concentration (X) and medicament to the growth inhibition percentage of target weed or the fresh weight inhibition percentage (Y) Equation, and calculate the EC of the pesticide on weeds 50 value or EC 90 value, and then calculate the co-toxicity coefficient. The co-toxicity coefficient was used to evaluate the joint effect of compound agents on weeds. The co-toxicity coefficient > 120 was indicated as synergistic effect, the co-toxicity coefficient between 80 and 120 was expressed as additive effect, and the co-toxicity coefficient < 80 was indicated as antagonism effect.

[0082] The calculation formula of co-toxicity coefficient adopted in the present embodimen...

Embodiment 2

[0090] Example 2 Preparation of wettable powder of wheat field herbicidal composition

[0091] In terms of mass percentage, take 3% of fluclopyridine ester, 50% of isoproturon, 3% of sodium lauryl sulfate, 5% of alkyl naphthalene sulfonate, 3% of fatty alcohol polyoxyethylene ether carboxylate, NNO (sodium methylene bis-naphthalene sulfonate) 12%, white carbon black 6%, light calcium carbonate to make up to 100%, mix evenly, and after jet crushing, 53% fluclopyridine-isoproturon wettability powder.

Embodiment 3

[0092] Example 3 Preparation of wettable powder of wheat field herbicidal composition

[0093] In terms of mass percentage, take 0.1% of fluclopyridine, 0.9% of isoproturon, 11% of pull-off powder, 12% of sodium polyacrylate, and attapulgite to make up to 100%, mix evenly, and after airflow crushing, 1% is obtained Fluclopyridine Isoproturon wettable powder.

Abstract

The invention belongs to the technical field of agricultural pharmacology and discloses a wheat field weeding composition and a medicine preparation thereof. The wheat field weeding composition is composed of a component 1 and a component 2, wherein the component 1 is halauxifen-methyl and the component 2 is selected from flucarbazone, mesosulfuron, fenoxaprop-P-ethyl, clodinafop-propargyl, pinoxaden or isoproturon. In the wheat field weeding composition, the two components are compounded with each other so that a synergistic effect is achieved. Medicine effects are significantly improved. The wheat field weeding composition can effectively prevent and treat weeds in a wheat field and can be widely applied in the field of agriculture.

Description

technical field [0001] The invention belongs to the technical field of pesticide science, and in particular relates to a wheat field herbicide composition and a pharmaceutical preparation thereof. 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 food in the world. crop. The perennial planting area of ​​wheat in my country is more than 30 million hectares, second only to the planting area of ​​rice. According to statistics, most wheat fields have suffered from weed damage 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 about 28%, and the loss of yield accounts for about 15% of the total wheat output. With the development of agricultural science and technology, the application of chemical herbicides has becom...
