Embodiment 1

[0043] Example 1: Indoor toxicity determination of tembotrione, fenflumezone, atrazine and their compound pair barnyardgrass (Echinochloacrusgalli), crabgrass (Digitarias anguinalis), and velvetleaf (Abutilontheophrasti.)

[0044] Table 1. Indoor toxicity test results of tembotrione, fenflumezone, atrazine and their compound pair barnyardgrass (Echinochloacrus galli).

[0045]

[0046] The combination of herbicides was evaluated according to the Colby method. The data in Table 1 show that the triple combination of tembotrione, fenflumezone, and atrazine has a significant synergistic effect on barnyardgrass (Echinochloacrus galli), E 0 -E values ​​are all greater than 20%.

[0047] Table 2. The results of indoor toxicity test on crabgrass (Digitarias anguinalis).

[0048]

[0049] According to the Colby method to evaluate the combination of herbicides, the data in Table 2 shows that the ternary combination of tembotrione, fenflumezone, and atrazine is effective on crabgr...

Embodiment 2

[0053] Example 2: (Embotrione · Oxentrazone · Atrazine Water Dispersible Granules)

[0054]

[0055] 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 this material into an extrusion granulator to extrude and granulate. After granulation, it is dried and sieved to obtain the corresponding weight percentage of tembotrione · fenflumezone · atrazine Water dispersible granules.

Embodiment 3

[0056] Example 3: (Embotrione · Oxentrazone · Atrazine wettable powder)

[0057]

[0058] 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 · oxazone · atrazine wettable powder.

Abstract

The invention discloses a pesticide composition containing tembotrione, topramezone and atrazine. The effective ingredients of the pesticide composition comprise the tembotrione, the topramezone and the atrazine, wherein the weight percent of the tembotrione in the pesticide composition is 1%-40%; the weight percent of the topramezone in the pesticide composition is 1%-40%; the weight percent of the atrazine in the pesticide composition is 1%-60%; and the rest is the pesticide auxiliaries. The components of the pesticide composition provided by the invention are reasonable; the pesticide composition has synergies response to the weeds in the corn field and especially has obvious synergies effects on barnyard grass, crab grasses and wild cotton; the weeding spectrum of single agent is expanded; the risk of weed resistance is reduced; and the pesticide composition is fit for preventing and killing the 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 response pesticide composition with tembotrione, fenfenzone, and atrazine as active ingredients, especially a synergistic response to barnyardgrass, crabgrass and velvetleum Obviously, it 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] Topramezone, a pyrazolone post-emergence stem and leaf treatment agent, can be absorbed by roots, young stems and leaves, and inhibits the double oxidation of 4-hydroxyphenylpyruvate in plastoquinone biosynthesis The enzyme (4HPPD), which indirectly affe...
