Embodiment 2

[0036] Example 2: Indoor toxicity test of tembotrione, nicosulfuron, atrazine and their compounds on Amaranthus spinosus, Cirsium setosum and Acalypha australis.

[0037] Table 4. Indoor toxicity test results of tembotrione, nicosulfuron, atrazine and their compound pair Amaranthus spinosus

[0038]

[0039] According to the Colby method to evaluate the combination of herbicides, the data in Table 4 shows that the triple combination of tembotrione, nicosulfuron, and atrazine has a significant synergistic effect on Amaranthus spinosus, E 0 -E values ​​are all greater than 20%.

[0040] Table 5. Indoor toxicity test results of tembotrione, nicosulfuron, atrazine and their compound pair Cirsiumsetosum

[0041]

[0042] According to the Colby method to evaluate the combination of herbicides, the data in Table 5 shows that the ternary combination of tembotrione, nicosulfuron, and atrazine has an effect on Cirsiumsetosum, E 0 -E values ​​are all greater than 20%.

Embodiment 3

[0046] Example 3 (Tensulfone·Tensulfuron·Atrazine water-dispersible granules).

[0047]

[0048] 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 tembotrione, thiazone, and atrazine. Water dispersible granules.

Embodiment 4

[0049] Example 4 (Tensulfone·Tensulfuron·Atrazine wettable powder).

[0050]

[0051] 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 tembotrione thiazone-methyl-atrazine wettable powder.

Abstract

The invention discloses a corn field weeding composition. The corn field weeding composition is composed of 1-40wt% of an effective component A, 1-10wt% of an effective component B, 1-50wt% of an effective component C, and the balance of a suitable pesticide assistant, the effective component A is tembotrione, the effective component B is one selected from thiencarbazone-methyl and nicosulfuron, and the effective component C is atrazine. The composition has the advantages of weeding improvement effect, weed control spectrum enlargement, low toxicity, low residual, and substantial reduction of the drug dosage, the use frequency and the use cost, has obviously better effects than single doses, and is a novel composition medicine having a good control effect on annual weeds in the corn field.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a synergistic herbicidal composition with tembosulfone, thionsulfuron or nicosulfuron and atrazine as active ingredients, which is suitable for controlling annual weeds in corn fields. Background technique [0002] Tembotrione is a triketone selective herbicide, which can effectively control the main broad-leaved grasses and some grass weeds, such as velvetleum, amaranth, quinoa, Polygonum, barnyardgrass, crabgrass, etc. Good control effect, can be used for pre-emergence sealing treatment and post-emergence stem and leaf treatment. [0003] Thiencarbazone-methyl is a sulfonylaminocarbonyl triazolinone herbicide and an acetolactate synthase inhibitor. Thiensulfuron-methyl can effectively control grass weeds in corn fields such as crabgrass, goosegrass, barnyardgrass, foxtail, etc. and most broad-leaved weeds. It is registered for use in corn (field, sweet corn, pop...
