Abstract

The invention discloses a preventing and treating composition for phylosticta cucurbitacearum sace. The composition is prepared from the following components in parts by weight: 3 to 5 parts of 25 percent thiophanate methyl wettable powder, 3 to 5 parts of 3 percent calcium nitrate, 3 to 6 parts of polyethylene glycol, 2 to 5 parts of 15 percent wettable nitrofen, 3 to 5 parts of radix sophorae flavescentis, 2 to 4 parts of baicalein and 1 to 3 parts of 5 percent polyvingl alcohol. Mixing the materials and preparing the same into a stock solution for later use, diluting the stock solution into a 600 to 1,000 times (volume ratio) dilution by adding water. The phylosticta cucurbitacearum sace can be treated by spraying the dilution. The composition provided by the invention is simple in ratio, and convenient to use, and has good treatment effect on spot disease. The effect is improved by 11 to 16 percent in comparison with that of a traditional market drug for preventing and treating the spot disease.

Description

technical field [0001] The invention belongs to the technical field of disease prevention and control of agricultural products, and in particular relates to a composition for preventing and treating gray asterella meloni. Background technique [0002] Melon cinerea, a fungus belonging to the subphylum Deuteromycota. Convex mirror-shaped pycnidia, 80-100 microns in diameter, brown, membranous. Conidia are oblong, slightly curved, single cell, transparent, colorless, 5-6×2.5 microns in size, which mainly cause spot disease or early blight, spot disease, mainly damage leaves, and mostly occur during the flowering and fruiting period. The middle and lower leaves are prone to disease, and the upper leaves have relatively less chance of disease. In the early stage of the disease, the lesions were water-soaked, then turned light brown, and the middle part was lighter in color, gradually dried up, surrounded by a water-soaked light green halo, and the diameter of the lesions was...
