Abstract

The invention discloses application of a compound composition of cymoxanil and eugenol in the field of agriculture, and particularly relates to an application study for preventing and curing downy mildew and phytophthora blight caused by phytophthora and downy mildew. According to the application of the compound composition of the cymoxanil and the eugenol in preventing and curing tomato late blight, grape downy mildew and cherry stem rot, the weight ratio of the cymoxanil to the eugenol in the compound composition is (100:1)-(1:50), the synergism ratio is (50:1)-(10:1), and the optimal ratiois 50:1. The compound composition of the cymoxanil and the eugenol has outstanding performance in preventing and curing tomato late blight, grape downy mildew and cherry stem rot.

Description

technical field [0001] The invention relates to a compound composition containing cymoxanil, especially cymoxanil and eugenol compounded and used as a fungicide to prevent and treat crop diseases caused by oomycetes, belonging to a compound composition of fungicides technology field. Background technique [0002] Oomycetes are an important class of plant pathogenic bacteria, widely parasitic on various crops, causing the roots, stems and leaves of grains, fruit trees, vegetables and ornamental plants, etc., causing diseases of plant roots, stems, leaves and fruits. Although oomycetes have similar structures with fungi in morphology, such as hyphae, appresses, haustoria and spores, etc., but they are similar to diatoms and brown algae from a genetic point of view, and belong to the kingdom of whip organisms. Plant pathogenic oomycetes can cause great damage to the economy and the environment, such as the European potato famine caused by Phytophthora infestans, and the sudden...
