Abstract
The invention provides a method for preventing and controlling tea garden tea geometrid by artemisia argyi essential oil. The artemisia argyi essential oil mainly comprises camphor, borneol, cineole, alpha-cadinene and the like. The artemisia argyi essential oil is prepared according to 50ml/L to 100ml/L, the consumption of the artemisia argyi essential oil in per mu is 1.125ml to 4.5ml, the artemisia argyi essential oil is diluted for 1000 to 2000 times, and is uniformly sprayed to a tea garden in the tea geometrid generating period, and the harm of the tea geometrid to tea trees can be effectively reduced. The medicine effect is the highest on the 7th day after the medicine application, the prevention effect on the tea geometrid reaches more than 85 percent, and the prevention effect on the tea geometrid still reaches more than 70 percent after the 10 days of the medicine application. The method has the advantages that no pollution is generated, the method conforms to the pest and disease damage green prevention and control principle, and conforms to the building requirement of a standard ecological tea garden, the operation is simple and convenient, and the cost is low.
Description
Technical field
The present invention is plant protection field, tea place, relates to argy wormwood essential oil control tea place tea geometrid new method.
Background technology
Tea geometrid all endangers seriously in Ge great Cha district of China, because it is heavy, and easy population outbreak.At present, Ge Cha district is mainly based on chemical control.Along with development and the needs of preserving the ecological environment of society, the agricultural chemicals etc. of less-persistent pesticide and environmentally safe has caused the very big concern of people, and the development and utilization of botanical pesticide has become the focus paid close attention to both at home and abroad.Its essence of botanical pesticide is chemical pesticide, but it extracts by natural plants, environmentally friendly, insect is not easily made to develop immunity to drugs, can make pest population density long-term control under economy is injured tolerable injury level, therefore, appliable plant insecticide control tea geometrid is a selection preferably.
Argy wormwood essential oil is formed by natural tarragon extracting refining, and outward appearance is pale yellow or green-yellow, mainly containing cineole, camphor, borneol, piperitol, α-Cadinene etc. Multiple components, is a kind of natural vegetable insecticide.Because it comes from nature, there is nontoxic or low toxicity, to person poultry safety, easily decompose under natural environment, and not easily produce resistance, not only better can reach the pest-resistant vermins-proof effect of desinsection, and safer to environment, also more secure to the quality safety of tealeaves.
Summary of the invention
Object of the present invention mainly provides a kind of argy wormwood essential oil to prevent and treat tea place tea geometrid new method, improve tea place tea geometrid control rate, improve tea leaf quality on the one hand, reduce residue of pesticide, reduce tea place agricultural chemicals to the pollution of environment, effectively make use of abundant argy wormwood resource on the other hand.
The present invention will disclose a kind of simple to operate, efficient tea place tea geometrid prevention and controls.The argy wormwood essential oil solution of preparation certain proportion concentration that the method mainly comprises the steps: (1); (2) evenly spray in tea tree in the tea place tea geometrid outbreak period.
Step 1) in, argy wormwood essential oil solution concentration is 50ml/L-100ml/L;
Step 2) in, after the argy wormwood essential oil solution dilution 1000 times-2000 times of configuration, evenly spraying dosage on tea tree is argy wormwood essential oil 2.25ml ~ 4.5ml/ mu.
Described argy wormwood essential oil control tea place tea geometrid new method, reaches most high-drug-effect, still can reach more than 70% after preventive effect can reach more than 85%, 10 days to tea geometrid preventive effect after 7 days.
