According to the pesticide composition, a remarkable synergistic effect within the proportioning range is shown, the using dose of pesticide is reduced, application times of the pesticide are reduced, the pesticide use cost is reduced, and adverse influence of pesticide on an ecological environment is reduced; a weeding spectrum is enlarged, and by one-time pesticide application, various weed problems are solved, and the defects and the limitation of single-dose use are made up; the service life of the pesticide is prolonged, and important significance for integrated management of weed resistance is realized. The pesticide composition is quick in pesticide efficiency playing, long in duration and low in use cost, and can be used for controlling gramineous weeds and broadleaf weeds in the wheat field.

The invention discloses an herbicide composition containing isoproturon, pretilachlor and diflufenican and a use thereof. Active components of the herbicide composition comprise isoproturon, pretilachlor and diflufenican. A mass ratio of isoproturon, pretilachlor to diflufenican is 10-50: 10-50: 1-20. The herbicide composition has obvious synergism in the above ratio range, reduces an herbicide use amount, reduces herbicide use frequency, reduces an herbicide use cost, reduces the unfavorable influence produced by the herbicide on an ecological environment and enlarges a weeding spectrum. Through one herbicide use step, various weed problems are solved and defects and limitation of single-ingredient herbicide use are overcome. The herbicide composition prolongs a service life and has an important meaning for comprehensive control of weed resistance. The herbicide composition can fast produce effects for a long time, has a low use cost and can be used for preventing and controlling gramineous weeds, broadleaf weeds and cyperaceae weeds in a paddy field and gramineous weeds and broadleaf weeds in a wheat or barley field.

The invention discloses a bactericidal composition containing fluxapyroxad and zinc thiozole. The bactericidal composition comprises active ingredients such as fluxapyroxad and zinc thiozole, and chemical additives, the weight ratio of the fluxapyroxad to zinc thiozole is (1 to 10) to (10 to 1), and the total weight of the fluxapyroxad and zinc thiozole in the composition is 1 to 95 percent; according to real application requirement, the bactericidal composition can be prepared into one of water emulsion, micro-emulsion, suspension agent, wettable powder and water dispersible granules and is used for preventing rhizoctonia solani. The pesticidal effect of the bactericidal composition can be played rapidly and lasts for a long time, the application cost is low, the use is convenient, time and labor are saved, and the economic benefit and social benefit are vast when the bactericidal composition is popularized to use.

The invention discloses an insecticide composition containing tefluthrin and cyromazine. The insecticide composition comprises effective components tefluthrin and cyromazine, wherein the weight ratio of tefluthrin to cyromazine is (1:15)-(15:1); the total weight of tefluthrin and cyromazine accounts for 2-80% of the insecticide composition in percentage by weight. The insecticide composition containing tefluthrin and cyromazine can be prepared as a suspending agent, a micro-capsule suspending agent, emulsion in water, microemulsion, an ultra-low volume liquid, wettable powder, an aqueous dispersion granular agent and granules according to practical application demands, and can be applied to prevention and treatment on chive maggots in Chinese chive fields.

The invention discloses a pesticide combination for preventing and controlling crop powdery mildew.
