Description
Technical field
The present invention relates to composition pesticide and its application fields, are specifically with cephalotaxus alkaloids and methoxyfenozide
The binary complex of effective active composition compounding, is mainly used in the prevention of pest on crops.
Background technology
Caephalotaxus sinensis is a kind of distinctive plant of China, has very high nutritive value and economic value, cephalotaxus alkaloids are thick
One of important active ingredient of Chinese torreya is usually used in having anti-cancer efficacy in drug, shows cephalotaxus alkaloids to agriculture according to another correlative study
The pests such as the mythimna separata, the striped rice borer that occur in industry have preferable control effect.Heretofore described cephalotaxus alkaloids according to
The cephalotaxus alkaloids product preparation method that embodiment 1 provides in Chinese invention patent (CN104293854B) is made.
Methoxyfenozide (methoxyfenozide)：Belong to bishydrazide insecticide, is a kind of insect growth regulator, IGR.
It after pests medicament, that is, generates husking reaction and starts to cast off a skin, larva dehydration, hungry and dead is caused due to that cannot cast off a skin completely
It dies.It is mainly used for preventing the larva of lepidoptera pest.
The resistance problem of agricultural pests is a global problem, is always the emphasis class of agricultural science and technology worker concern
Topic.With the increase for using pesticide control pest continuity year in year out, Pesticide use amount and not scientifical use pesticide etc.
Factor leads to pest resistance getting worse, and the pest species for generating resistance are on the increase.Meanwhile the use pesticide of high intensity, it leads
Caused Practice for Pesticide Residue in Agricultural Products it is exceeded, pollution environment and peasant's drug cost increase a series of problems, such as, be unfavorable for agricultural can
Sustainable development.Therefore, efficient, low toxicity, low-residual, different role mechanism are developed, while having the compounding system of synergistic function again
Agent not only facilitates the generation for delaying pest resistance to insecticide, but also can extend the service life of pesticide species, reduces and uses agent
Amount, it is cost-effective, reduce the pollution to environment.
The present inventor sends out unexpectedly during furtheing investigate cephalotaxus alkaloids and methoxyfenozide compounded formula
Existing cephalotaxus alkaloids and methoxyfenozide are compounded, vertical to striped rice borer, the rice on rice within the scope of certain compound proportion
The pests such as leaf roll snout moth's larva have significant synergistic function, and control effect is good, and the lasting period is long, to rice safety, through further grinding
Study carefully, completes the present invention.
Invention content
The purpose of the present invention is to provide a kind of component is reasonable, obvious synergy, insecticidal effect is outstanding, the lasting period
Long, drug cost is low, pest can be delayed to develop immunity to drugs, and to the composition pesticide of Crop securify.
The composition pesticide system containing cephalotaxus alkaloids and methoxyfenozide that another object of the present invention is to provide a kind of
Agent dosage form.
It is still another object of the present invention to provide above-mentioned composition pesticides on prevention rice striped rice borer, rice leaf roller etc.
The purposes of pest.
Technical scheme of the present invention：To achieve the above object, present invention offer is a kind of containing cephalotaxus alkaloids and methoxy worm
The composition pesticide of hydrazides, effective active composition are made of cephalotaxus alkaloids and methoxyfenozide, cephalotaxus alkaloids and methoxy worm
The weight ratio of hydrazides is 20:1~1:40, preferred weight ratio 10:1~1:30, most preferably weight ratio is 1:7.
In composition pesticide of the present invention, the total weight percentage composition of cephalotaxus alkaloids and methoxyfenozide is
0.1%~85%, the preferably total weight percentage composition of cephalotaxus alkaloids and methoxyfenozide is 1%~70%.
Composition pesticide of the present invention can be prepared into the arbitrary application forms used in suitable agricultural production, compare
Good application forms have aqueous emulsion, microemulsion, missible oil etc..
In various application forms prepared by composition pesticide provided by the invention, other than effective active composition, further include
Allow to use and the various auxiliary elements of acceptable in pesticide.
The auxiliary element includes but not limited to solvent, wetting agent, dispersant, stabilizer, antifreezing agent, thickener, disappears
Infusion, bleeding agent, synergist, preservative etc. are all common in pesticidal preparations or allow the ingredient used, are not particularly limited,
Specific ingredient and dosage are according to the recipe requirements determined by the test.
The production technology of the various application forms of composition pesticide belongs to existing known technology, and details are not described herein.
Compared with the prior art, the advantages of the present invention are as follows：
1, cephalotaxus alkaloids and methoxyfenozide compounding have significant synergistic function, are used alone compared with single dose bright
The aobvious control effect improved to pest.
2, cephalotaxus alkaloids and methoxyfenozide two kinds of active components compounding, reduce Pesticide use amount, reduce use
Cost alleviates the pollution to environment.
3, cephalotaxus alkaloids and methoxyfenozide two kinds of active components compounding, the mechanism of action is different, and action site increases
Add, delayed the generation of pest resistance to insecticide, increases the service life of pesticide.
Specific implementation mode
To better understand the essence of the present invention, present disclosure is described further with reference to embodiment,
But limitation of the present invention cannot be considered as, it is as described below to be only used for explaining the present invention, for without departing from spirit of that invention and principle

Six cephalotaxus alkaloids of embodiment and the prevention snout moth's larva of rice field efficacy verification of methoxyfenozide complex composition preparation
Experiment
The prevention snout moth's larva of rice is carried out using cephalotaxus alkaloids provided by the invention and methoxyfenozide complex composition preparation
Field efficacy verification test, concrete outcome are shown in Table 3.
Control effect of the 3 each chemicals treatment of table to the snout moth's larva of rice
As can be seen from Table 3, using each composition pesticide preparation for preparing of the present invention, after medicine 15 days to two changes on rice
Snout moth's larva, rice leaf roller preventive effect 80% or more, the lasting period is long, hence it is evident that is better than 1% cephalotaxus alkaloids missible oil and 24% methoxy
Two single doses of Tebufenozide suspending agent are used alone.Meanwhile each pesticide group prepared using the present invention is not found during the test
Poisoning is generated to rice after closing object preparation.
In conclusion a kind of composition pesticide containing cephalotaxus alkaloids and methoxyfenozide provided by the invention, collaboration
Synergistic effect is notable, improves preventive effect compared to the exclusive use of each single dose, can effectively prevent striped rice borer on rice, rice leaf roller etc.
Pest, the lasting period is long, to rice safety, is worth being widely applied in agricultural production.
