Description
Technical field
The invention belongs to agriculture plant protection field, more particularly to a kind of Pesticidal combination with improvement performance.Tool
Body is related to a kind of Synergistic insecticidal compositions comprising AVM and the methaldehyde.
Background technology
Active component AVM (Abamectin) is a kind of agricultural or for animals sterilization being widely used, desinsection, mite killing
Agent.AVM has stomach toxicity and action of contace poison to mite class and insect, it is impossible to ovicidal.Mechanism of action is different from general insecticide
It is interference nervous physiology activity, stimulates release GABA, and aminobutyric acid has to arthropodan nerve conduction suppression to make
With.Mite class adult, nymph and insect larvae occur paralysis symptom with AVM after contacting, inertia, do not take food, 2～4 days
Dead afterwards.Because not causing insect rapid dehydration, so AVM lethal effect is slower.AVM to insect predator and
Though insect parasite has direct action of contace poison, lack because plant surface is remained, therefore the damage very little to beneficial insect.AVM is in soil
Interior will not be moved by adsorption by soil, and be decomposed by the microorganisms, thus in the environment nothing cumulative function, can be used as integrated control
A part.Modulation easily, is used by preparation is poured into water slightly stirring, also safer to crop.
The secondary methaldehyde of active component (Metaldehyde) is a kind of strong insecticide of selectivity, has peat-reek, has very
Strong allure.After spiral shell is taken food or touch medicament by the attraction of attractant, acetylcholinesterase in breechblock is made to release in a large number
Put, special mucus in breechblock is destroyed, breechblock rapid dehydration, neural paralysis is made, and mucus is secreted, due to the loss of a large amount of body fluid
It is destroyed, causes breechblock, slug etc. to be poisoned to death at short notice with cell.
Actual agricultural chemicals experience have shown that, repeats and single-minded applies a kind of reactive compound to prevent and treat agricultural pests very
Target organismses fast selective will be caused in the case of many, and the mixture of different activities compound be usually used at present to prevent and treat evil
Worm.By the reactive compound with the different mechanisms of action is combined, can delaying drug resistance produce, reduce amount of application, reduce
Cost accounting.
Content of the invention
The purpose of the present invention is for insecticide resistance and pedo relict problem in actual applications, filters out containing two
Plant the insecticide AVM of different desinsection principles and the methaldehyde is compounded, so that insecticide control effect is improved, delay to resist
Property produce, reduce amount of application, reduce cost accounting.
It is a further object of the present invention to provide a kind of above-mentioned composition pesticide prevents and treats crops mollusk in agriculture field
Purposes in insect pest.
The purpose of the present invention can be reached by following measures：
The invention provides a kind of Pesticidal combination with synergistic effect, containing effective constituents A and B in said composition,
Effective constituents A is AVM, and active ingredient B is the methaldehyde.
Inventor is found by experiment that above-mentioned Pesticidal combination synergy is obvious, it is often more important that amount of application is reduced, and reduction makes
Use cost.Different from the compound structure type of component B containing component A, mechanism of action is different, and both are compounding being capable of expanding prevention
Spectrum, and can no interactions resistance between the generation of delaying drug resistance and development speed, and component A and component B to a certain extent.
The active ingredient of the present composition can only include A and B, it is also possible in the base for not affecting composition overall performance
On plinth, include other active ingredients further.

2nd, drug effect checking test
(1) Assays Example
Using AVM as standard agent, disease index and prevention effect is calculated.Prevention effect is converted into niqueMin
Y (), liquor strength (μ g/ml) are converted into logarithm value (x), calculate concentration EC50 in virulence equation and suppression with least square method,
Toxicity index level co-toxicity coefficient (CTC) of medicament is calculated according to the abundant method of Sun Yun.Toxicity test the results are shown in Table 1.
Actual measurement toxicity index (ATI)=(standard agent EC50/ reagent agent EC50) * 100
Percentage composition+B medicament toxicity index * the mixture of A in theoretical toxicity index (TTI)=A medicament toxicity index * mixture
The percentage composition of middle B
Co-toxicity coefficient (CTC)=[mixture actual measurement toxicity index (ATI)/mixture theoretical toxicity index (TTI)] * 100
CTC≤80, composition show as antagonism, 80 ＜ CTC ＜ 120, and composition shows as summation action, and CTC >=
120, composition shows as synergistic effect.
1st, AVM and the compounding toxicity test to brassicaceous vegetable snail of the methaldehyde are tested
1 AVM of table is analyzed with the compounding toxicity test to brassicaceous vegetable snail of methaldehyde different ratio
As a result (table 1) shows, AVM is with the methaldehyde in proportioning 1：Between 0.1～80, co-toxicity coefficient all 125 with
On, illustrate that the compounding preventing and treating to snail of AVM and the methaldehyde has a significant synergistic function, and 1：0.1～80
Outside interval, then only show the summation action to snail.
(2) field control effectiveness test
1st, the field control effect of AVM and the methaldehyde is verified using embodiment obtained in the present invention.
Each process of the test of pesticide effectiveness is repeated 4 times, in the uniform dispenser of insect pest occurrence in peak period.Each processes cell and takes 5 at random
Individual, per demarcation 1m2, insect population is investigated before dispenser, record within 7 days after dispenser residual borer population living, calculate Revision insect recluced rate, i.e.,
Prevention effect.While investigate having or not symptom of chemical damage for studying thing.Determine the security of medicament.
Expected preventive effect (%)=X+Y-XY/100 (wherein, X, Y are single dose preventive effect)
2. AVM of table and the compounding field efficiency test result to paddy rice Pomacea canaliculata of the methaldehyde
Measurement result (table 2) shows that AVM is substantially carried with the compounding preventive effect to preventing and treating paddy rice Pomacea canaliculata of the methaldehyde
Height, illustrates that the two compounding has significant synergistic function to paddy rice Pomacea canaliculata.In whole process of the test, combine in the present invention
In the amount ranges of thing preparation, the poisoning phenomenon to paddy growth is not found, illustrate that the composition of the present invention to paddy growth is
Safety.
