Problems solved by technology

Farmers have extensive planting management, usually do not pay attention to prevention, and only take pesticide poisoning measures when pests and diseases break out. The prevention and control is passive and lagging behind. Frequent use of pesticides will lead to environmental pollution, increased resistance to pests and diseases, and food safety hazards.

Abstract

The invention discloses a method for comprehensive prevention and control of pollution-free sweet potato diseases, insect pests and weeds. Disinfect seedlings, beware of carrying diseases and insect pests; S5, close weeding after planting; S6, prevent diseases and insects after slowing seedlings; S7, intertill weeding, prevent and control underground pests; the present invention follows the plant protection policy of "prevention first, comprehensive prevention and control", with " Based on the principle of harmless control based on biological control and supplemented by chemical control, comprehensive prevention and control measures have been formulated from preparation for tillage, land preparation, seedling treatment to the entire growth period, so that the pests and diseases in sweet potato planting can be controlled from the time of preparation for tillage. The prevention and control work has been carried out to avoid situations such as the decrease of sweet potato yield and the increase of pesticide residues caused by the use of pesticides after the discovery of insect pests; the present invention can improve the yield and quality of sweet potatoes, reduce the use amount and residue of pesticides, protect the natural ecological environment, and conform to the development requirements of sustainable green agriculture.

Description

technical field [0001] The invention relates to the technical field of agricultural production, in particular to a method for comprehensive prevention and control of pollution-free sweet potato diseases, insect pests and weeds. Background technique [0002] Sweet potato belongs to traditional agriculture. With the continuous improvement of people's living standards, its health functions such as anti-cancer and immunity enhancement are more and more favored by consumers. The planting area of ​​fresh sweet potatoes is gradually increasing, and the harm of sweet potato diseases, insect pests and weeds is becoming more and more serious. , especially the sweet potato ants, wireworms, and grubs in the southern potato area are seriously harmful. Farmers have extensive planting management and usually do not pay attention to prevention. They only take pesticide poisoning measures when pests and diseases break out. The prevention and control appears to be passive and lagging behind. F...
