Abstract

The present invention relates to a seed dressing agent, especially to a potato seed dressing agent. The potato seed dressing agent is characterized in that: 50% dimethomoph, 80% mancozeb and 72% agricultural streptomycin are firstly mixed; then an adsorption sustained-release agent and an additive are added to obtain the potato seed dressing agent, wherein a weight ratio of the dimethomoph to themancozeb to the agricultural streptomycin is (1.2-3.2%):(0.1-0.64%):(0.06-0.16%), the adsorption sustained-release agent is bentonite, the weight percentage of the adsorption sustained-release agent is 84-92.64%, the additive is potassium dihydrogen phosphate, the weight percentage of the additive is 6-12%. According to the present invention, the purpose of the present invention is to solve the problem of fungus in the soil of the potato successive cropping land; the low-toxicity, high-efficiency, and low-residue agent is introduced, and is assisted by microelements, high-quality nutrient substances, and the like to prepare into the seed dressing agent, such that the infection of the harmful substances in the soil to the potato seed is effectively blocked, the infection of the pathogenic bacteria to the potato seed surface is inhibited, the seedling emergence rate of the potato seed is improved, the disease resistance of the potato is enhanced, and the potato seed dressing agent provides the guarantee for the potato yield increasing.

Description

technical field [0001] The invention relates to a seed dressing agent, in particular to a potato seed dressing agent. Background technique [0002] Ningxia is one of the main potato producing areas in northern my country. For a long time, potatoes have been a food and vegetable crop in the southern counties of Ningxia, and the planting area has exceeded 4 million mu. Among the potato diseases in Ningxia, late blight, early blight and black mole are the most harmful. In recent years, the potato planting area has expanded, continuous cropping is more common, and farmers' awareness of disease prevention and treatment is weak, and potato diseases occur in large areas. According to statistics, the annual incidence of potato diseases in Ningxia is about 30%, and in serious years it is more than 50%, and the yield loss can reach more than 20%. The control measures are mainly chemical spraying during the disease occurrence period, the control rate is low, and the control effect is...
