Problems solved by technology

In the slightest, it will affect the normal growth and development of cucumbers, and in severe cases, it will cause a serious reduction in production and affect the quality of cucumbers.
Moreover, this disease has the characteristics of easy infection, fast infection, rapid development, and difficult control.
At present, pesticides such as carbendazim, chlorothalonil, Dupont-Cl, and phosphine aluminum are mainly used for prevention and control in production. They may not have the proper therapeutic effect due to their single effect. For example, the main function of "chlorothalonil" is to prevent Fungal infection, no systemic conduction effect, unable to kill the pathogens invading crops; or due to enhanced resistance and short duration, such as "carbendazim" and "ethylphosphonium aluminum", although they have good systemic properties , the treatment effect is obvious, but it is easy to produce resistance and reduce the efficacy; while "72% Kelu" can achieve the purpose of prevention and treatment, but the effective period is short, the relative cost is high, and it is difficult for farmers to accept

Abstract

The invention discloses a pesticide composition for preventing and curing cucumber downy mildew. The pesticide composition comprises three fungicides, namely, chlorothalonil, azoxystrobin and cyazofamid, and is used for preventing and curing the cucumber downy mildew by adopting a compound preparation. The pesticide composition has complementarity, an internal absorbing drug and a protective drug are mixed for use to form multiple acting sites, and thus a target is unlikely to have drug resistance. As the three fungicides are mixed for use, the control range can be enlarged, the preventive treatment effect is enhanced, the drug toxicity is lowered, the optimum drug application period is prolonged, the preventive treatment cost is saved, the drug application frequency is reduced, the adaptation property is reinforced, and the generation of the drug resistance of the target is delayed.

Description

technical field [0001] The invention relates to a fungicidal pesticide, in particular to a pesticide composition for controlling cucumber downy mildew. technical background [0002] Cucumber downy mildew is a common disease, which can occur in both seedling and adult plant stages of cucumber. In the slightest, it will affect the normal growth and development of cucumbers, and in severe cases, it will cause serious production reduction and affect the quality of cucumbers. Moreover, this disease has the characteristics of easy infection, fast infection, rapid development, and difficult control. At present, pesticides such as carbendazim, chlorothalonil, Dupont-Cl, and phosphine aluminum are mainly used for prevention and control in production. They may not have the proper therapeutic effect due to their single effect. For example, the main function of "chlorothalonil" is to prevent Fungal infection, no systemic conduction effect, unable to kill the pathogens invading crops; ...
