Description
Technical field
The present invention relates to plant pest management technical fields, and in particular to a kind of medicine based on herbs for preventing and treating bradysia odoriphaga.
Background technique
The pesticide residue excessive problem for applying chemical pesticide initiation in leek production for prevention and treatment bradysia odoriphaga is exactly current agricultural
Most one of the outstanding problem being widely noticed in production.Bradysia odoriphaga is a kind of intractable subterranean pest-insect, can grow to leek and bring destruction
Property harm, the pesticide species of the bradysia odoriphaga of profession prevention and treatment at present are seldom, substantially with phoxim (organophosphorus insecticide) and chlopyrifos (in
Deng malicious pesticide) based on, although it is insecticide of the national approved applications into leek, since leek has absorbability biology special
Property and harvest time in growth period short feature, even if being considered as the chemical pesticide for permitting applying on leek, the dish that has in practice
Agriculture is not applied as required, and when leek is gathered in, not up to security interval also results in excessive pesticide residues, causes to human body
Harm.The most serious is constantly enhancing due to resistance of the bradysia odoriphaga to these chemical pesticides, even if these chemical pesticides increase dosage,
Also lost the control to bradysia odoriphaga, many peasant households helplessly apply high poison, persistent pesticide in violation of rules and regulations, less serious case cause people because
It eats high poison leek and the symptoms such as headache, nausea occurs, severe one even threat to life.It constantly looks in countries in the world, research and develop and replace
For in the highly effective and safe of high poison chemical pesticide, the spring tide of environmentally friendly new product, many enterprises and research institutions start to answer
Botanical pesticide technology is restudied with modern biotechnology.It is continuous with research in the obstinate field of pest control such as bradysia odoriphaga
It carries out in a deep going way, the effective prevention component of many Chinese traditional herbs is determined, extracts, and the Chinese herbal medicine applied to agriculture field is not
It is disconnected to increase, but there are higher cost, using convenient not as good as chemical pesticide or preventive effect is unstable etc. due to, be never suitble to
On a large scale, low cost, high preventive effect, the professional prevention product appearance using simplicity.
In the prior art about the report of botanical pesticide prevention and treatment bradysia odoriphaga, as Chinese patent CN104086325A is disclosed
A kind of method of biological control bradysia odoriphaga, the invention use the method prevention and treatment fragrant-flowered garlic mixed capsicum, Vitex negundo var cannabifolia and biogas slurry as medicament
Maggot, since Microflora is big in biogas slurry, can impact leek normal growth, simultaneously although environment friendly and pollution-free
Control efficiency is also undesirable.
Summary of the invention
To solve the above problems, bradysia odoriphaga control efficiency is good, together the present invention provides a kind of medicine based on herbs for preventing and treating bradysia odoriphaga
When can also reduce other pest and disease damages, and also have effects that improve crops yield and quality.
To achieve the above object, the technical scheme adopted by the invention is as follows：
