Abstract
The invention discloses a pyraclostrobin-containing agricultural bactericidal compound composition. The composition is compounded by active ingredients, namely pyraclostrobin (A) and a bactericide (B), wherein the bactericide (B) is any one of triflumizole, hymexazol and carbendazim; the weight ratio of the pyraclostrobin (A) to the bactericide (B) is (1:50)-(50:1); and the active ingredients account for 5 to 60 percent of the total weight of the agricultural bactericidal compound composition. The composition can be prepared into the conventional formulations such as water dispersible granules, wettable powder, a suspension, an oil-based suspension, microemulsion, emulsion in water, spreading oil, sustained-release granules and the like. The composition is used for controlling agricultural plant diseases, and is particularly used for controlling diseases such as powdery mildew, anthracnose and leaf spot disease of melons, vegetables and fruit trees, rice seedling blight, pyricularia oryzae, rice sheath blight disease and the like. The invention has the advantages that: the bactericide composition is efficient and has long duration, the environmental pollution is reduced, and the like.
Description
technical field [0001] The invention belongs to the technical field of pesticides, and relates to a pesticide composition, in particular to an agricultural bactericidal compound composition containing pyraclostrobin. Background technique [0002] At present, for the prevention and control of diseases that are prone to resistance in agriculture, it is the best choice to use pesticide varieties with different action mechanisms for mixing. The effect of a single dose. Fungicides containing a single active ingredient often have certain defects in the prevention and control of agricultural diseases. Continuous repeated use not only makes pathogenic bacteria prone to drug resistance, but also easily causes pollution to food and the environment. Reasonable mixing of active ingredients in fungicides The above disadvantages can be overcome. The synergistic effect of the active ingredients through reasonable compounding can improve the control effect, reduce the amount of active ing...
