50value.
(4) the joint toxicity measuring method of different proportionings
According to the toxicity test result of single dose, by active ingredient 20% ratio of weight and number imicyafos: Avermectin is respectively 19.9:0.1,19.5:0.5,19:1,18:2,17:3.
Adopt above-mentioned 1.3 methods to carry out toxicity test, calculate LC
50, and press the abundant method of Sun Yun and calculate co-toxicity coefficient (CTC).Co-toxicity coefficient CTC, computing formula is as follows: (take imicyafos as standard medicament, its toxicity index is 100):
The LC of toxicity index (the TI)=imicyafos of Avermectin
50the LC of/Avermectin
50× 100
The LC of actual toxicity index (ATI)=imicyafos of M
50the LC of/M
50× 100
TI × P Avermectin of TI × P imicyafos+ Avermectin of theoretical toxicity index (TTI)=imicyafos of M
TTI × 100 of the ATI/M of co-toxicity coefficient (CTC)=M of M
In formula:
M is Avermectin and the mixture of the different proportionings of imicyafos
P Avermectin is Avermectin shared ratio in mixture
P imicyafos is imicyafos shared ratio in mixture
(5) toxicity test result and analysis
The indoor measurement result of table 1imicyafos, Abamectin on Plutella
As can be seen from the table, in the mixture of different proportion, its co-toxicity coefficient is all greater than 120, shows certain synergistic effect, wherein imicyafos: the synergistic effect that Avermectin is 19.5: 0.5 is the most obvious, and co-toxicity coefficient is 189.00.Result of the test shows, under indoor conditions, Avermectin, two kinds of medicaments of imicyafos all have higher activity to diamond-back moth, the result of the test of different proportion proportioning shows, by active ingredient imicyafos: when Avermectin is 19.9:0.1,19.5:0.5,19:1,18:2,17:3, all show stronger synergistic effect, wherein take imicyafos: Avermectin is 19.5: 0.5 o'clock, and synergistic effect is best.Suggestion is carried out further field control effectiveness test to the mixture preparation of suitable proportion 19.5:0.5 left and right scope, to evaluate its field practical application effect.
Field experiment: field experiment control wild cabbage damage by disease and insect
(1) test method
Test is sprayed medicine 1 time altogether, and the dispenser date is on June 18th, 2012.Now not yet balling of wild cabbage, diamondback moth larvae major part is in 2～3 length of times, and during spray medicine, weather is cloudy calm, and with sharp agriculture board level pressure knapsack hand sprayer, to each processing even spraying, leave dual sides all requires to be sprayed with effect liquid, every community liquid 2L.
(2) investigation method
Investigate each community and fix 15 strain wild cabbages as investigation strain, record the larva quantity on whole blades, spray the front investigation of medicine insect population radix, respectively 3,7 days and investigation in 10 days borer population alive after spray medicine.This test is investigated 3 times altogether.
(3) drug effect computational methods
Borer population * l00 lives before insect population decline rate (%)=(borer population of living after borer population one dispenser of living before dispenser)/dispenser.
Preventive effect (%)=(treatment region insect population decline rate-check plot insect population decline rate)/(100-check plot insect population decline rate) * 100.
(4) poisoning investigation method
After dispenser, 10d range estimation medicament does not have poisoning to produce to crop continuously, wild cabbage well-grown.
(5) field control effectiveness test result of the test
Table 2 treatment agent control diamond-back moth field control effectiveness test result
As can be seen from Table 2,19.5%imicyafos+0.5% Avermectin is that the successful of the mixture combination control diamond-back moth of 19.5: 0.5 is better than 1.8% Avermectin EC, 20%imicyafos SC and contrasts single dose, 19.5%imicyafos+0.5% Avermectin insecticidal effect of 7 days after medicine is respectively 92.33%, 93.84% and 94.52%, and insecticidal effect increases progressively along with the increase of consumption.Within the scope of test dose, plant growth is normal in addition, and the poisoning phenomenon to wild cabbage does not all appear in each treatment agent, illustrates that it is safe to wild cabbage.
