Abstract
The invention discloses a kind of Pesticidal combinations containing double third ring worm esters and paichongding, including the double third ring worm esters of effective component and paichongding and common auxiliary element, the weight ratio of double third ring worm esters and paichongding in the composition are 1:20-20:1.Great number of indoor and outdoor experiments show that after being compounded, Pesticidal combination of the present invention especially has significant synergistic function to homoptera pest, mini pest, while dosage is reduced to the various pests for the growth that harms the crops, good to crop safety.
Description
Technical field
The present invention relates to agricultural insecticide composition and its application fields, are specifically with double third ring worm esters and paichongding
The binary complex of active constituent compounding.
Background technique
Double third ring worm esters, a kind of brand new and the insecticide with completely new mechanism of action, to sucking pest such as aleyrodid,
Aphid, plant hopper, scale insect and leafhopper all have very high virulence, can be used for vegetables, fruit tree, vine, imtertilled crop and sight
Appreciate plant etc..
Paichongding belongs to novel nicotinic insecticide, and the mechanism of action is the axis synaptic receptor for acting on insect nerve,
Block nerves conduction；Alimentary system either is acted on, the pest for feeding paichongding generates food refusal reaction etc..
Different pesticide species ingredients are compounded, and are the common methods for preventing and treating agriculture resistant insect.The present inventor is a large amount of
Indoor virulence and field medicine effect test on the basis of, the screening of the compounded formulas of double third ring worm esters and paichongding is goed deep into
Research, the double third ring worm esters of discovery and paichongding are compounded, are had obvious synergistic function in a certain proportion,
And there is outstanding control efficiency to complete the present invention after further study the pests such as homoptera pest, mini pest.
Summary of the invention
The object of the present invention is to provide a kind of the compound synergic Pesticidal combination containing double third ring worm esters and paichongding, application
With prevention and treatment homoptera pest, the pests such as mini pest.
Technical solution: a kind of Pesticidal combination containing double third ring worm esters and paichongding, effective component is by double third ring worm esters
It is formed with paichongding, the weight ratio of double third ring worm esters and paichongding in the composition is 1:20-20:1, double third ring worm esters and piperazine worm
The weight percent of pyridine weight summation in the composition is 5%-93%, remaining is to allow in pesticide using auxiliary with acceptable
Co-ingredients.
Composition pesticide of the present invention can be prepared into any one dosage form for being suitble to agriculturally use by known method, than
Preferable dosage form has suspending agent, water dispersible granules, aqueous emulsion, missible oil, microemulsion, wettable powder.
The production technology of the various application forms belongs to existing known technology, and details are not described herein.
Auxiliary element used in the present composition includes solvent, emulsifier, wetting agent, stabilizer, dispersing agent, thickening
Agent, pH adjusting agent, defoaming agent, antifreezing agent, packing agent etc. be beneficial to effective component it is stable in the formulation and play drug effect it is known
Substance, is all various composition commonly used or allowed to use in pesticidal preparations, and specific ingredient and dosage pass through examination according to recipe requirements
Test determination.
Pesticidal combination of the present invention is for preventing and treating homoptera pest.
The frequency of administration and amount of application of Pesticidal combination of the present invention change with crops, pest, weather condition and have a small amount of
Variation, can achieve the purpose that effectively prevent by using dosage appropriate.
Compared with the prior art, the advantages of the present invention are as follows:
1, double third ring worm esters and flonicamid compounding have unexpected synergistic function, are used alone than single dose
Improve the control efficiency to pest；
2, double third ring worm esters and the flonicamid mechanism of action are different, the mixed generation that can delay pest resistance to insecticide；
3, two kinds of effective component compoundings of double third ring worm esters and flonicamid, reduce Pesticide use amount, reduce use
Cost and alleviate the pollution to environment.

Malicious coefficient (CTC) is all larger than 120, shows synergistic function to rice hoppers, it is seen that double third ring worm esters and paichongding
Compounding has reasonability and feasibility.
Embodiment 7: the indoor joint toxicity measuring test of double third ring worm esters and paichongding to apple aphid
For test worm: indoor for many generations to raise Individual Size and consistent 3 instar larvae of aphid of physiological status.
Reagent agent: 94% pair of the third ring worm ester raw medicine and 95% paichongding raw medicine.
Test method: using malicious blade method is pressed from both sides, the specific method is as follows.
It is beaten first with the punch of diameter 1cm and takes leaf butterfly, be put into culture dish, moisturizing.It then will be each with capillary dropper
For treatment agent since low concentration, every 1 μ L medical fluid of leaf butterfly drop is coated with the leaf butterfly pair of gelatinized corn starch with another after the solvent is volatilized
The malicious leaf butterfly of folder is made in conjunction, and production, which finishes, to be put in the hole of 12 hole tissue culturing plates.Last inscribed 1 examination in each hole of tissue culturing plate
Worm is placed in 26 ± 1 DEG C of temperature, in the intelligent insectary that relative humidity is 70%.After connecing worm 2~4 hours, contain to test worm feeding is complete
After medicine leaf butterfly, clean feeds are added in cultivation plate hole and continue raising to investigating, eliminate the test worm for not eaten a complete leaf butterfly.
Every processing sets 4 repetitions, and every repetition is no less than the malicious leaf butterfly of 12 folders, and the processing for setting the corresponding organic solvent without medicament is made
For control.72h investigates test worm death condition after processing, records total borer population and dead borer population.
It is for statistical analysis with DPS statistical analysis software, calculate the LC of each medicament50, and mixture is calculated according to Sun Yunpei's Method
Co-toxicity coefficient (CTC value.)
Survey toxicity index (ATI)=(standard agent LC50/ reagent agent LC50)×100
Percentage composition+B the medicament toxicity index of A in theoretical toxicity index (TTI)=A medicament toxicity index × mixture × mixed
The percentage composition of B in agent
Co-toxicity coefficient (CTC)=[mixture surveys toxicity index (ATI)/mixtures theoretical toxicity index (TTI)] × 100
Act on the criteria for classifying according to NY/T11547.7-2006 insecticide combination: co-toxicity coefficient (CTC) >=120 shows as increasing
Effect effect；Co-toxicity coefficient (CTC)≤80 shows as antagonism；80 < co-toxicity coefficient (CTC) < 120 show as summation action.
The indoor joint toxicity measuring result of 2 pairs of the third ring worm esters of table and paichongding to apple aphid
From table 2 it can be seen that when double third ring worm esters and paichongding compound in the range of 20:1~1:20 (by weight), altogether
Malicious coefficient (CTC) is all larger than 120, shows synergistic function to aphid, it is seen then that double third ring worm esters and paichongding compounding tool
There are reasonability and feasibility.
In conclusion a kind of Pesticidal combination containing double third ring worm esters and paichongding provided by the invention, synergistic
Effect is significant, and compared with existing single formulation, the effect for preventing and treating pest on crops is significantly improved, and to Crop securify, holds
The effect phase is long, is worth promoting and applying in agricultural production.
