Embodiment 1

[0042] Example 1: Indoor virulence determination test of fluopyron, chlorpyrasulfuron, atrazine and their combination pairs Setariaviridis, Abutilontheophrasti, Cyperusrotundus L..

[0043] Table 1. Indoor toxicity test results of fluopyrin, chlorpyrisulfuron-methyl, atrazine and their combination with Setariaviridis.

[0044]

[0045] According to the Colby method to evaluate the combination of herbicides, the data in Table 1 show that the ternary combination of fluroxypyr, chlorpyrisulfuron, and atrazine has a significant synergistic effect on Setariaviridis, E 0 -E values ​​are all greater than 20%.

[0048] According to the Colby method to evaluate the combination of herbicides, the data in Table 2 show that the ternary combination of fluopyron, chlorpyrisulfuron, and atrazine has a significant synergistic effect on Abutilontheophrasti, E...

Embodiment 2

[0052] Example 2: Flurpyridone·Chlorpyrasulfuron·Atrazine water dispersible granules.

[0053]

[0054] Add the above materials into a cone mixer and mix them evenly, then pulverize by a jet mill. The crushed materials are then mixed by a cone mixer. The mixed material has a fineness of 98% and passes through a 600-mesh standard sieve and is added to the kneader. Kneaded into plastic materials, and finally put this material into an extrusion granulator to extrude and granulate. After granulation, after drying and sieving, the corresponding weight percentage of fluopyron, chlorpyrisulfuron, and atr were obtained. Dispersible granules to remove body water.

Embodiment 3

[0055] Example 3: Flurpyridone·Chlorpyrisulfuron·Atrazine WP.

[0056]

[0057] Add the above materials into a cone mixer and mix them evenly, and then pulverize by a jet mill. The crushed materials are then mixed by a cone mixer. The fineness of the mixed materials is 98% and passes through a 600-mesh standard sieve to obtain the corresponding weight. The percentage of fluopyrin·chlorpyrisulfuron·atrazine wettable powder.

Abstract

The invention relates to a pesticide composition. Bicyclopyrone, halosulfuron-methyl and atrazine serve as active ingredients of the pesticide composition. The pesticide composition is prepared from, by weight, 1%-30% of bicyclopyrone, 1%-30% of halosulfuron-methyl, 1%-50% of atrazine and the balance pesticide adjuvants. The pesticide composition is prepared from reasonable components, has a synergistic effect on corn field weeds, has an obvious synergistic effect especially on setaria viridis, abutilon theophrasti and cyperus rotundus, broadens the weeding spectrum of a single dose and lowers the risk of resistance of weeds.

Description

Technical field [0001] The invention belongs to the technical field of pesticides, and specifically relates to a pesticide composition with synergistic response that uses fluopyrone, chlorpyrisulfuron, and atrazine as effective ingredients, and is suitable for controlling annual weeds in corn fields. Background technique [0002] Bicyclopyrone, a triketo ketone herbicide, is absorbed by plant roots and leaves, and is transmitted in the body to inhibit hydroxyphenylpyruvate dioxidase, leading to the accumulation of tyrosine, plastoquinone and The biosynthesis of tocopherol ceases, which leads to a decrease in the content of chlorophyll, which causes the plant meristem to become bleached and die. It can prevent annual weeds. It can be treated with soil surface before seedling and stem and leaf treatment after seedling. The residual period in the soil is longer. Short, suitable for field corn, sweet corn, silage corn, seed-producing corn, yellow pop corn field to prevent and control...
