Abstract
The invention discloses a pesticide composition containing fenazaquin. The pesticide composition contains fenazaquin and pyridaben serving as active ingredients, wherein the weight part ratio of the two active ingredients comprising the fenazaquin and the pyridaben is 1:60-60:1. The composition can be used for preventing and controlling multiple pests, has obvious synergism, enlarges the mite killing spectrum, and has high activity on leaf mite, panonychus ulmi and the like on fruit trees, flowers, cottons, hot pepper and vegetables; the consumption of pesticide is reduced, the residue of the pesticide on crops is reduced, and environmental pollution is lightened; and the composition is safe to people and animals and has good environmental compatibility, and the harmful mites do not easily produce pesticide resistance.
Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of composition pesticide that contains fenazaquin.
Background technology
Fenazaquin (fenazaquin) molecular formula: C
20H
22N
2O, chemical name: 4-spy-butyl benzene ethyl quinazoline-4-base ether, fenazaquin is the quinolines miticide, by mitochondria and the chromosome set I of action of contace poison in insect cell, occupied the abutment of ubiquinone. to orange tree, cotton tree two spotted spider mite is had the better prevention effect, and the lasting period is long, to natural enemies security.
Pyridaben (pyridaben) molecular formula: C
19H
25ClN
2OS, chemical name: (4-tertiary butyl benzylthio-4-chloro-3 (H)-pyridazin-3-one, pyridaben is wide spectrum, tagging property miticide to 2-tertiary butyl-5-, can be used for preventing and treating multiple food vegetalitas evil mite.To whole growth phase of mite be ovum, young mite, if mite with becomes mite that good effect is all arranged, have tangible speed to kill equally to the one-tenth mite of mobile phase and act on.Field efficacy can be kept 30～40 days, even longer, and this medicine is not acted upon by temperature changes, and no matter uses in early spring or autumn, all can reach promising result.
Yet in the real process of agricultural production, the problem that control evil mite is easy to generate most is the drug-fast generation of evil mite.Important harmful mite such as Panonychus citri, tetranychid on the agricultural, because its breeding cycle is short, breeding amount is big, and mobility is little, and selfing degree height is easy to generate resistance especially.
The different cultivars composition carries out composite, is to prevent and treat the very common method of resistance evil mite.Heterogeneity is carried out composite, according to practical application effect, judge certain composite be synergy, add and or antagonism.In most cases, the composite effect of agricultural chemicals all is an additive effect, and the seldom composite of synergistic effect really arranged, especially synergistic effect very obviously, co-toxicity coefficient very high composite just still less.Through inventor research, find fenazaquin and pyridaben can produce good synergistic effect after composite, and still unexposed about the composite relevant report of fenazaquin and pyridaben.
Summary of the invention
Degradation problem under the resistance generation that the long-term use of fenazaquin list agent may bring, the drug effect, the composition pesticide that the present invention proposes contains fenazaquin, two kinds of active components of pyridaben, and an amount of surfactant and carrier.
A kind of composition pesticide that contains fenazaquin comprises effective active component, auxiliary agent and filler, it is characterized in that: active component fenazaquin, pyridaben ratio of weight and number are 1: 60～60: 1.

The embodiment of the invention is the method that adopts Toxicity Determination and field trial to combine.Pass through Toxicity Determination earlier, the co-toxicity coefficient (CTC) after clear and definite two kinds of medicaments are composite by a certain percentage, CTC＜80 are antagonism, and 80≤CTC≤120 are summation action, and CTC＞120 are synergistic effect, on this basis, carry out field trial again.
Test method: respectively the mother liquor of each mixed agent is diluted to five series concentration during test, places beaker standby respectively.Adopt and to soak the method that connects mite behind the leaf earlier, the blade of the same size that does not contact any medicament soaked in the soup that configures behind the 5s take out, dry naturally, put into and support the mite box, connect then, under 25 ℃ of conditions, raise for the young mite of examination, every processing repeats for 3 times, every to repeat used examination mite number be 50, establishes blank simultaneously, checks dead mite number in 72h, calculate lethality and corrected mortality, try to achieve virulence regression equation and calculate LC
50Value.If the contrast lethality then is considered as invalid test greater than 10%.Computing formula is as follows:
To do harm to the mite corrected mortality and be converted into probit value (y), concentration of treatment (μ g/ml) converts logarithm value (x) to, draws virulence regression equation with method of least squares, and calculates the value of every kind of medicament thus.Calculate co-toxicity coefficient CTC according to the abundant equation of Sun Yun.Computing formula following (with the fenazaquin is the standard medicament, and its toxicity index is 100):
TI * the P of theoretical toxicity index (TTI)=fenazaquin of M
FenazaquinTI * the P of+pyridaben
Pyridaben
In the formula: M is the mixture of different proportionings;
P
PyridabenBe pyridaben shared ratio in composition;
P
FenazaquinBe fenazaquin shared ratio in composition.
Application Example two:
For trying the evil mite: Panonychus citri.
Test medicine provides by Shaanxi Welch Crop Protection Co., Ltd..
Experimental scheme: effective lethal concentration scope of determining fenazaquin, the former medicine of pyridaben and the two different proportioning mixture through preliminary experiment.
Toxicity test result one
The different proportionings with pyridaben of table 5 fenazaquin are to the toxicity test of Panonychus citri
As shown in Table 5, the proportioning of the composite control Panonychus citri of fenazaquin and pyridaben was at 60: 1 to 1: 60 o'clock, co-toxicity coefficient is all greater than 120, illustrating that both were mixed in the scope at 60: 1 to 1: 60 all shows synergistic effect, especially when fenazaquin and pyridaben get proportioning at 2: 1 to 1: 8, synergistic effect is more obviously outstanding, co-toxicity coefficient maximum when fenazaquin and pyridaben weight ratio are 1: 2 wherein, and synergistic effect is the most obvious.
Application Example three fenazaquins and pyridaben and the composite control cotton tetranychid test of pesticide effectiveness thereof
This experimental establishment is at Shaanxi Province's Weinan City Baishui County, and test medicine is researched and developed, provided by Shaanxi Welch Crop Protection Co., Ltd., contrast medicament 95g/L fenazaquin missible oil (commercial), 20% pyridaben wetting powder (commercial).
Investigation cotton tetranychid mite evil index in the their early stage dispenser, was investigated mite evil indexes in 24 hours, 72 hours after the dispenser and is calculated preventive effect before the medicine.Experimental result is as follows:
Table 6 fenazaquin, pyridaben and the composite control cotton tetranychid test of pesticide effectiveness thereof
As can be seen from Table 6, can effectively prevent and treat the cotton tetranychid after fenazaquin and pyridaben are composite, control efficiency all is better than the preventive effect of single agent.In the test scope of medication, the target crop is had no adverse effects.
