Embodiment 1
[0041] Example 1: 50% propargyl oxadiazone·pyrimifluben·ciprosulfuron-methyl water-dispersible granules.
[0042] Oxadiazone propargyl 35%, pyrimifluben 5%, cyprosulfuron 10%, sodium lauryl sulfate 6%, alkylphenol polyoxyethylene ether 8%, urea 2%, kaolin supplement 100%. Mix the above-mentioned active ingredients, dispersant, wetting agent, disintegrant and solid carrier evenly, pulverize with an ultrafine jet mill, knead, and then add to a fluidized bed granulation dryer for granulation, drying, and sieving. 50% propargyl oxadiazone·pyrimifluben·ciprosulfuron-methyl water-dispersible granules can be prepared.
Embodiment 2
[0043] Example 2: 70% propargyl oxadiazone·pyrimifluben·cyprosulfuron-methyl wettable powder.
[0044] 40% propargyl oxadiazone, 10% pyrimifluben, 20% cyprosulfuron-methyl, 6% sodium lauryl sulfate, 6% alkylphenol polyoxyethylene ether formaldehyde condensate, 100% made up of diatomaceous earth . Mix the above-mentioned active ingredients, dispersant, wetting agent and solid carrier, mechanically pulverize, then airflow pulverize, and mix evenly to obtain 70% propargyl oxadiazone · pyrimifluben · cyprosulfuron wettability powder.
Embodiment 3
[0045] Example 3: 20% propargyl oxadiazone·pyrimifluben·cyprosulfuron-methyl oil suspension concentrate.
[0046] 15% propargyl oxadiazone, 3% pyrimifluben, 2% cyprosulfuron, 10% alkylphenol polyoxyethylene ether, 10% sodium dodecylbenzene sulfonate, 1.5% hydroxymethyl cellulose , Refined soybean oil makes up 100%. After the above-mentioned active ingredients and additives are dispersed by high-speed shearing and sand-milled in a sand mill, a highly dispersed and stable suspension system is formed in a non-aqueous medium to prepare 20% propargyl oxadiazone. Ether Cyprosulfuron-methyl oil suspension.

Abstract
The invention discloses a weeding composition containing cyclosulfamuron. The weeding composition comprises effective components consisting of oxadiargyl, pyriminobac-methyl and cyclosulfamuron, with the balance being auxiliary components permitted and acceptable in pesticides, wherein a weight ratio of oxadiargyl to pyriminobac-methyl to cyclosulfamuron is 1-50: 1-40: 1-40, and the total weight percentage content of oxadiargyl, pyriminobac-methyl and cyclosulfamuron in the composition is 0.1 to 85%. The composition exerts obviously better effects in preventing and eliminating annual weeds in a paddy field compared with separately used effective components of the composition, has a broadened weed control spectrum, reduces drug dose, delays generation of drug resistance of weeds and mitigates pollution to the environment.
Description
technical field [0001] The invention relates to a pesticide herbicidal composition and its application field, in particular to a herbicidal composition with oxadiazone propargyl, pyriflun-methyl and cyprosulfuron-methyl as active ingredients, which is applied to the control of annual weeds in paddy fields. Background technique [0002] Chemical weeding is one of the main means to control farmland weeds in agricultural production. In recent years, due to the large-scale single use of some herbicide varieties, many weeds have developed resistance. Simultaneously, because weeds occur when the grass phase is complex and there are many types, the use of a single species can no longer effectively solve the damage caused by weeds in farmland, and all will show a certain aspect of defects. The mixed use of different types of herbicides has many advantages such as broad weeding spectrum, improved control effect, delay of weed resistance, saving time and labor. [0003] Oxadiargyl: ...
