Description
Technical field
The present invention relates to a kind of insecticide, in particular to a kind of Thuja extract insecticide and preparation method thereof.
Background technique
Arbor-vitae is a kind of common trees in China, research has shown that, flavonoids is mainly contained in Cacumen Platycladi extract and is mixed
Matter and volatile oil etc. have good medical value, and have stronger bacteriostatic activity to various bacteria and fungi.Insecticide quilt
It is widely used in agriculture, woods, herds etc. in the various production activity of the mankind.
With the development of modern science technology, chemical pesticide is because its adaptation is wide, easy to operate, at low cost, significant effect
The advantages that be widely used.But also just because of a large amount of uses of chemical pesticide, bring many new problems, such as to the dirt of environment
Dye, pesticide residue, pest and disease damage drug resistance etc..Due to the requirement of environmental protection and the proposition of Green Chemistry, modern should be
The higher pollution-free pesticide of safety or public nuisance-free agricultural chemicals are compatible with the environment, the unique environment friendly agricultural of mechanism of action.
In numerous new pesticides, plant insecticide not only conforms with the direction of current Agrochemicals, complies with protection ring
The trend in border, and some vegetable insecticides from mechanism of action be compared with common insecticides in the mode of action matter fly
Jump, is particularly suitable for the high added values such as fruit and vegetable agricultural product and city control of insect.Plant insecticide has safety, high
The advantages of effect, low toxicity, the chemical pesticides such as low-residual cannot match in excellence or beauty, with it, itself is degradable, non-harmful in the natural environment
Advantage has become one of first choice of environment friendly agricultural.
Pesticide conventional dosage forms such as missible oil, pulvis and wettable powder account for 80% in China's preparation total amount, in recent years
Carry out the continuous development with the formulations of pesticide, the shortcomings that conventional dosage forms more aobvious protrusion.Have in missible oil containing a large amount of dimethylbenzene, toluene etc.
Solvent not only causes more serious pollution to environment, but also causes waste to fossil resources.Wettable powder is due to its grain
Degree is very thin, often occurs dust from flying in the production and use process, not only endangers people's health, also will cause environment dirt
Dye, a small amount of dust from flying are easy to that crops is made to generate phytotoxicity.Pulvis main problem is dust drift, and volume is big, is not easy to measure,
It is now used only for arid area and some particular places.Water dispersible granule insecticide effectively avoids the deficiency of these conventional dosage forms
Place draws and is utilized its advantage, develops extremely rapid, it is considered to be before 21st century pesticide processing field is most developed
One of dosage form of scape.But the current type of water dispersible granule insecticide is less, and prescription collocation owes reasonable.How preferably to open
The application of arbor-vitae is sent out, the insecticide for preparing more environmentally-friendly green is current problem to be solved.
Summary of the invention
It is an object of the present invention to overcome the deficiencies of the prior art and provide a kind of Thuja extract insecticide, this hair
