Embodiment 1

[0017] Various single-component active ingredient pesticides or multi-component active ingredient pesticide compositions and pesticide compositions containing β-cyclodextrin and urea were prepared into wettable powders, and then sprayed on the sugarcane field, at the sugarcane seedling stage Spray according to the corresponding amount of active ingredients, see the following table for the specific spraying settings, dosage and herbicidal effect, where the control efficiency refers to the percentage of the number of weeds that have died and cannot resume growth after observation to the total number of weeds before spraying .

[0018]

[0019] Through the field test, it is also found that the herbicidal composition containing β-cyclodextrin and urea, that is, the composition No. 10-13, after spraying on the sugarcane field, the drying time of the weeds It should be 2-3 days in advance, that is, the time for weeds to affect sugarcane production is shortened, so after adding th...

Embodiment 2

[0020] Example 2 Sugarcane herbicidal composition 1

[0021] Mix 6Kg of ametryn, 15Kg of Diuron, 2Kg of β-cyclodextrin, 3Kg of urea, 5Kg of cottonseed oil, and 3Kg of ethylene glycol polyoxyethylene ether, and stir to obtain the sugarcane field weed control combination.

Embodiment 3

[0022] Embodiment 3 sugarcane herbicidal composition 2

[0023] Mix 12Kg of arazine, 24Kg of diuron, 4Kg of dimethyltetrachloride, 4Kg of β-cyclodextrin, 8Kg of urea, 18Kg of cottonseed oil, and 9Kg of ethylene glycol polyoxyethylene ether, and stir , to obtain the herbicidal composition for sugarcane field.

Abstract

The invention relates to a herbicidal combination containing ametryn and diuron. The herbicidal combination contains the ametryn and the diuron as active ingredients, the total weight of the ametryn and the diuron is 10 to 30 parts by weight, wherein the weight ratio of the ametryn to the diuron is 1:1 to 5, the herbicidal combination also contains Beta-cyclodextrin and urea as adjuvants, the total weight of the Beta-cyclodextrin and the urea is 5 to 10 parts, wherein the weight ratio of the Beta-cyclodextrin to the urea is 1 to 3:4. The herbicidal combination guarantees the synergism between the herbicides, and moreover, the time of weed control is shortened.

Description

technical field [0001] The invention belongs to the field of agricultural chemistry, and in particular relates to a herbicidal pesticide composition comprising endametraz and diuron, in particular to a herbicide comprising ametraz and diuron, and also comprising β-cyclodextrin and Herbicidal pesticide compositions of urea. Background technique [0002] Ametryn is a triazine herbicide, also known as "atrazine", which is insoluble in water but easily soluble in organic solvents, and it is decomposed into 6-6 - Hydroxy derivatives. [0003] Diuron (Diuron) is a systemic broad-spectrum herbicide of urea, mainly used to control weeds in non-cultivated areas. It can be used to control crabgrass, goosegrass, foxtail, etc. in the fields of cotton, soybean, sorghum, and corn. [0004] The combination of ametraz and diuron showed a synergistic effect on some weeds, but for most of the weeds it only expanded the diuron and did not achieve effective synergistic effect. [0005] Thro...
