Embodiment Construction

[0011] Azadirachtin·berberine seed coating agent is composed of azadirachtin and berberine as bactericidal and insecticidal active ingredients. Then it is equipped with adhesives, synergists, stabilizers, film-forming agents, PH value regulators and pigments. Improve the retention rate of pesticides on seedlings, thereby improving the control effect. The inventor applied azadirachtin, berberine and other adjuvants with different content combinations to the red rot fungus, R. blight and anthracnose fungus that harm cotton; rice blast, sheath blight, bakanae disease, white leaf Indoor pathogenic bacteria inhibition and field biological effect plot tests were carried out for blight and knot nematode.

[0012]

[0013] The above treatments are safe for crops.

Abstract

A seed-coating agent is prepared from the nimbin extracted from the seeds of min tree and the berberine extracted from berbrioes plant through compounding. It can be used to prevent and elimiante underground pests, damping-off, white rot, etc.. Its advantages are high effect, lwo poison and no pollution.

Description

technical field [0001] The invention belongs to a mixed pesticide, and relates to pesticide formula and preparation technology. Background technique [0002] Due to the long-term dependence of human beings on a single type of fungicide, bacteria are prone to develop drug resistance, resulting in a sharp increase in the amount of chemical fungicides, which not only increases the economic burden on farmers, but also can cause environmental and agricultural product pollution. Currently, there are a large number of mixed fungicides on the market. However, most of them are mixtures of chemical pesticides, which are highly toxic to humans and animals and easily cause pollution. Moreover, after a long period of use, bacteria are also prone to develop drug resistance. [0003] Botanical pesticides come from nature, have good compatibility with the natural environment, have low toxicity, are not easy to cause environmental and agricultural product pollution, and bacteria are not easy...
