Embodiment 1

[0024] Example 1: Indoor toxicity of fluramiflub, flucarbazone, and its compound against Ludwigiaprostrata (LUDPR), Paspalum paspaloides (PASPA), and Leesia hexandra (LEEHE) Determination test.

[0025] According to the Gowing method to evaluate the combination of herbicides (NY / T 1155.7-2006), the formula is as follows:

[0026] E 0 = X + Y - X × Y 100

[0027] In the formula:

[0028] X is the fresh weight inhibition rate of the target weeds when fluramiflub is used alone at a certain dose;

[0029] Y is the fresh weight inhibition rate of target weeds when flucarbazone is used alone at a certain dose;

[0030] E. 0 It is the theoretical value or expected value of the fresh weight inhibition rate of target weeds when the two pesticides, flumeflub and flucarbazone, are used in combination;

[0031] ...

Embodiment 2

[0036] Example 2 (Water-dispersible granules of fluramiflub-sulfazone).

[0037]

[0038] 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, it is dried and sieved to obtain the corresponding weight percentage of Fluoxaflub-Sulfonacil Water Dispersible granules.

Embodiment 3

[0039] Example 3 (fluroflumecil-flumezone-sulam wettable powder).

[0040]

[0041] Put the above materials together into the conical mixer and mix them evenly, then pulverize them through the jet mill, and then mix the pulverized materials through the conical mixer. The fineness of the mixed materials is 98% and pass through a 600-mesh standard sieve to obtain the corresponding weight Percentage of Fluoxaflub-Sulfonacil WP.

Abstract

The invention relates to a weeding composition containing fluoropyribenzoxim and triafamone. Effective components of the weeding composition are fluoropyribenzoxim and triafamone. The weeding composition disclosed by the invention has a synergistic interaction response to target weeds, is suitable for preventing and removing annual weeds in rice fields, and is particularly suitable for preventing and removing the annual weeds in the rice fields which take ludwigia prostrate, paspalum paspaloides and Leersia hexandra as dominant weeds.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a synergistic responsive pesticide composition with fluramiflub and flucarbazone as active ingredients, which is suitable for controlling annual weeds in paddy fields, especially Polygonum cloves, Polygonum cloves, Paspalum bitacica and Lishihe are the dominant annual weeds in paddy fields. Background technique [0002] Fluoxaflub is obtained by introducing trifluoromethyl substitution on specific positions of pyrimidine salicylic acid compounds. It is an acetolactate synthase inhibitor, and it shows excellent control performance against perennial and annual grass weeds. Broad-spectrum selective post-emergence herbicide, especially effective in controlling barnyardgrass, paspalum, paddy barnyard and red-footed barnyard in paddy fields. The dosage per mu is 2-6 grams. Fluoxafen is highly safe for rice sex, [0003] Triafamone is an amide compound, a broad-spectrum...
