Embodiment 1

[0015] Embodiment 1: biological assay embodiment.

[0016] Flupropafen-ethyl, penoxsulam and their complex pairs Sesbania exaltata, SESEX=田草), Commelina diffusa (COMDI=竹节花), Leptochloa chinensis, LEPCH=daughter sub) endotoxicity assay.

[0017] According to the Gowing method to evaluate the combination of herbicides (NY / T1155.7-2006), the formula is as follows:

[0018] E 0 = X + Y - X × Y 100 .

[0019] In the formula:

[0020] X is the fresh weight inhibition rate of target weeds when flumethazine is used alone at a certain dose;

[0021] Y is the fresh weight inhibition rate of the target weeds when penoxsulam is used alone at a certain dose;

[0022] E. 0 It is the theoretical value or expected value of the fresh weight inhibition rate of the target weeds when the two agents of fluprop...

Embodiment 2

[0028] Example 2 (37% flupropafen-penoxsulam water-dispersible granule).

[0029]

[0030] Put the above materials together into the conical mixer and mix them evenly, and then crush them through the jet mill, and then mix the crushed materials through the conical mixer. Knead into a plastic material, and finally put the material into an extrusion granulator to extrude and granulate. After granulation, dry and sieve to obtain 37% fluprofen-pentoxsulam water-dispersible granules agent.

Embodiment 3

[0031] Example 3 (25% flupropafen-penoxsulam wettable powder).

[0032]

[0033] Add the above materials together into a conical mixer and mix them evenly, then pulverize them through a jet mill, and then mix the pulverized materials through a conical mixer. The fineness of the mixed materials is 98% and passes through a 600-mesh standard sieve to obtain 25% Flupropafen-Penoxsulam wettable powder.

Abstract

The present invention relates to a herbicidal composition, the active ingredients of which are flumethazone-methyl and penoxsulam, and the weight-number ratio of flumethazone-methyl and penoxsulam is 30:1-1:30; The present invention is suitable for controlling weeds in orchards, non-cultivated land, vine crop fields, and cotton fields. Compared with a single agent used alone, the weeding effect is obviously improved, the herbicidal spectrum is expanded, and the crops are safe. At the same time, the amount of pesticide usage is reduced, and the Pesticides pollute the environment and delay the emergence of weed resistance.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a synergistic herbicidal composition with flupropafen-ethyl and penoxsulam as active ingredients, which is suitable for preventing weeds in non-cultivated land, orchards, and vine crop fields. Background technique [0002] Butafenacil, a non-selective uracil herbicide, is mainly used in orchards, non-cultivated land, cotton fields, and vine crop fields to control important broad-leaved weeds, gramineous weeds, and sedge weeds , It can also be used for pre-emergence weeding of crops such as wheat, and the effective dose of weeding is more than 50 grams of active ingredients per hectare. [0003] Penoxsulam is a conductive herbicide, absorbed by stems, leaves, young shoots and roots, and transmitted to meristems through xylem and phloem, inhibiting plant growth, making growing points chlorotic, and terminal buds turn red 7-14 days after treatment , necrosis, and pla...
