Problems solved by technology

[0003] At present, chemical pesticides are mainly used for the prevention and control of stem nematodes, among which many kinds of organophosphorus insecticides are used for the chemical control of the nematodes, such as Shennongdan, methimenphos, ketendan and other pesticides to prevent and control stem rot. Nematodes, although certain effects have been achieved in the initial stage of prevention and control, due to the high toxicity, high residues, low safety and serious environmental pollution of such agents; in addition, the long-term and large-scale use of these agents has caused stem nematodes to develop resistance to pesticides, making them more serious. Difficult to cure

Abstract

The invention provides sweet potato pesticide which is prepared according to a formula in parts by weight: 8 to 32 parts of camphor tree leaves, 5 to 30 parts of garlic, 5 to 25 parts of purslane and2 to 20 parts of artemisia apiacea. The pesticide is outstanding in prevention and treatment effect on stem eelworms of sweet potatoes, goes green, and is environmentally friendly and pollution-free.

Description

technical field [0001] The invention relates to the field of plant disease and insect pest control, in particular to a sweet potato insecticide. Background technique [0002] Stem nematode disease of sweet potato, commonly known as bran heart disease, is a dangerous and destructive disease. It mainly infects the stems and vines of seedlings and harms potato tubers, resulting in poor development of stems and tubers, small and deformed tubers, and severe field plant growth. Yellow withered, melon pieces rotted, resulting in severe yield reduction, or even no harvest. [0003] At present, chemical pesticides are mainly used for the prevention and control of stem nematodes, among which many kinds of organophosphorus insecticides are used for the chemical control of the nematodes, such as Shennongdan, methimenphos, ketendan and other pesticides to prevent and control stem rot. Nematodes, although certain effects have been achieved in the initial stage of prevention and control, ...
