Pesticide for camellia oleifera trees

Abstract

The invention provides a pesticide for camellia oleifera trees. The pesticide is prepared from, by mass, 10-15% of traditional Chinese medicine extract liquor, 0.2-0.5% of sodium chloride, 0.4-0.8% of sodium dehydroacetate, 0.2-0.6% of nisin, 0.2-0.5% of an active ingredient and the balance water. The traditional Chinese medicine extract liquor is prepared by mixing raw materials and then carrying out alcohol extraction, wherein the raw materials include, by weight, 2-3 parts of radix hemerocallis, 4-5 parts of herba gendarussae, 1-4 parts of rosmarinic acid, 1-2 parts of muskmelon pedicel, 2-4 parts of fresh rhizoma imperatae, 0.5-1.5 parts of herba lophatheri, 0.2-0.4 part of aloe, 0.2-0.4 part of asiatic toddalia roots, 0.2-0.4 part of Oriental stephania roots and 0.2-0.4 part of caulis piper wallichii. The active ingredient is obtained by extracting alangium chinense seeds and pumpkin seeds in the weight ratio of 1:4. The pesticide can be degraded in nature and is good in environment compatibility, free of residues or pollution, safe to people and livestock and environmentally friendly.

Description

[0001] 【Technical field】 [0002] The invention relates to the planting field of camellia oleifera, in particular to an insecticide for camellia oleifera. [0003] 【Background technique】 [0004] Camellia oleifera is a unique woody oil family plant in China, and 80% of the camellia oleifera resources in the world are distributed in my country. Camellia oleifera seeds and their by-products have extremely high economic value, and camellia oil has great competitive potential in the international market. At present, the development status of my country's Camellia oleifera industry is that the proportion of afforestation of improved varieties is small, the proportion of old residual forests is high, the scientific high-yield cultivation technology is lacking, the management is extensive, and the diseases and insect pests of Camellia oleifera are common, such as: camellia oleifera soot, camellia oleifera anthracnose, camellia oleifera, etc. If left unchecked, it will cause a large nu...

Problems solved by technology

At present, the development status of my country's Camellia oleifera industry is that the proportion of afforestation of improved varieties is small, the proportion of old residual forests is high, the scientific high-yield cultivation technology is lacking, the management is extensive, and the diseases and insect pests of Camellia oleifera are common, such as: camellia oleifera soot, camellia anthracnose, camellia oleifera, etc. If left unchecked, it will cause a large number of flower buds, fruits, and leaves to fall off and dry up, and even the whole plant will die, resulting in low yield of camellia oleifera; in order to prevent and control pests and diseases of camellia oleifera, a large amount of chemical fertilizers and pesticides are used to spray, causing serious imbalance of soil microorganisms, soil compaction, and soil fertility. Decrease in fertilizer efficiency, low utilization rate of fertilizers and pesticide residues, causing serious pollution to soil environment and water resources
