Abstract

The invention belongs to the technical field of compound compositions of bactericides, relates to an oxathiapiprolin and cnidiadin containing compound composition and application thereof, in particular to application of a bactericide compounded from oxathiapiprolin and cnidiadin to control of crop diseases caused by oomycetes. The compound composition comprises the oxathiapiprolin and the cnidiadin as active components, wherein the weight ratio of the oxathiapiprolin to the cnidiadin is 40:1 to 5:20. The oxathiapiprolin and cnidiadin containing compound composition is applied to the agricultural field, and particularly has a good control effect on phytophthora diseases caused by phytophthora (such as tomato late blight, cherry stalk rot and the like) and downy mildew caused by peronospora(such as grape downy mildew).

Description

technical field [0001] The invention belongs to the technical field of compound compositions of fungicides, and relates to a compound composition containing fluthiapiprofen and osthole and its application, especially the compounding of fluthiapiprofen and osthole as Fungicides are used to control crop diseases caused by oomycetes. Background technique [0002] Oomycetes are a class of eukaryotic microorganisms that are morphologically similar to fungi but closely related to diatoms and brown algae in evolutionary relationship. Phytophthora and downy mildew caused by Phytophthora in oomycetes are worldwide diseases, which threaten the quality and yield of agricultural products and affect the sustainable development of agriculture. [0003] At present, the control strategy for oomycete diseases in production is mainly chemical agent control, but the use of a large number of chemical agents causes a large number of pesticide residues, environmental pollution, damage to ecologi...
