Abstract

The invention relates to the field of potato late blight control, in particular to a method for controlling potato late blight. The method comprises the following steps: S1, about 10 days before sowing, selecting sunny weather, spreading a soil fungicide Serenadesoil along with fine ploughing, deeply ploughing for 40-50 cm, and standing for one week to complete soil preparation; and S2, before sowing seed potatoes, adopting a seed dressing agent prepared from berberine, quercetin, mangiferin, eugenol, alternaria tenuissima protein and conventional auxiliary material additives to complete seed dressing treatment of the seed potatoes. The method can effectively control the potato late blight, and significantly reduce the probability of potato late blight generation.

Description

technical field [0001] The invention relates to the field of preventing and treating late blight of potatoes, in particular to a method for preventing and treating late blight of potatoes. Background technique [0002] Potato late blight is a disease of potatoes caused by Phytophthora infestans. The disease mainly affects potato stems, leaves and tubers, but can also infect flower buds and berries. Potato infestans mainly overwinters in diseased potatoes with mycelium, and the main source of primary infection is diseased seed potatoes in northern my country, while diseased residues and infected spontaneous seedlings in southern production areas can also become the next source of infection. The primary source of infection for a season. After the diseased potato is sown, the mycelium on the potato piece develops upward with the young shoots and the plant. Generally, when the relative humidity continues to be above 90% and the temperature is above 10°C, the leaves are prone to...
