Implementation of an application example three：Biphenthrin and the field control effectiveness test of Rynaxypyr compounding
Field information embodiment 1 prevents and treats the field control effectiveness test of corn/corn borer
Reference《Pesticide field efficacy medicine test criterion（One）Insecticide control corn/corn borer GB/T 17980.6-2000》, examination
Test medicament, comparison medicament and the processing of the cell of blank control and use random alignment, plot area 50m2, often handle 4 repetitions.
Investigation and statistical method：50 plants of corns to be investigated per cell, count attacked trees rate, the work borer population of aggrieved strain is looked into stripping, with
Compare calculating relative control effect in check plot.In insect latter stage in the present age, i.e., investigate within 10 ~ 15 days after medicine.
Aggrieved strain rate（%）=（Aggrieved strain number/investigation total strain number）×100%；
Prevention effect（%）=（The aggrieved aggrieved strain rate of strain rate-chemicals treatment district of blank district）The aggrieved strain rate of/blank district ×
100%
From table 5,15 days after medicine, Biphenthrin and the preventive effect of Rynaxypyr complex preparation embodiment 1 ~ 15 are
92.21% ~ 96.19%, 100 g/l of Biphenthrin missible oil preventive effects of comparison medicament are 74.87%, 200 g/l of chlorine worms of comparison medicament
The preventive effect of benzamide suspending agent is 80.95%, and Biphenthrin and Rynaxypyr complex preparation preventive effect are apparently higher than comparison medicine
Agent single dose.During dispenser, poisoning generation is found no, to crop safety.
Field information embodiment 2 prevents and treats the field control effectiveness test of lichee/base of a fruit moth
Selection tree vigo(u)r is energetic, base of a fruit moth occurs more serious litchi and tested.This experiment is using Conopomorpha sinensis Bradley as preventing and treating pair
As, clear water blank control, the control of single dose drug effect.The 1st medicine, interval 7 are sprayed in the generation adult eclosion rate about 40% by design dosage
Dispenser once, dispenser 3 times altogether, each handles 10 plants of lichee, is repeated 3 times again for it.Lichee leaf positive and negative, the tip are uniformly sprayed
Mist, until blade face is dripped for degree.
Each 2 plants of processing investigation when lichee harvests, every kind of medicament investigates altogether 6 plants, respectively from East, West, South, North each side
Position grab sample, every plant of lichee fruit picking 50, takes back indoor inspection, peels off base of fruit with hand, counts wormed fruit number (having worm or frass),
Calculate wormed fruit rate and prevention effect.
Wormed fruit rate（%）=（Wormed fruit number/investigation fruit number）×100
Prevention effect（%）=[（Check plot wormed fruit rate-treatment region wormed fruit rate）/ check plot wormed fruit rate] × 100

This experiment reference《Pesticide field efficacy medicine test criterion（Two）Insecticide control tea tree tea geometrid, Euproctis pseudoconspersa GB/
T17980.55-2004》, test medicine, comparison medicament and the processing of the cell of blank control use random alignment, plot area
20m2, often handle 4 repetitions.
Investigation and statistical method：Per 2 sampling point investigation larva numbers living of cell mark.Radix is investigated before medicine, is adjusted within 1 ~ 3 day after medicine
Look into once, further investigation can be carried out by 7 days after medicine.
Revision insect recluced rate（%）=[（Borer population living after borer population-medicine living before medicine）Borer population living before/medicine] × 100%；
Preventive effect（%）=[（Treatment group Revision insect recluced rate-control group Revision insect recluced rate）/（100- control group Revision insect recluced rates）] ×
100%

Amine complex preparation preventive effect is higher than comparison medicament single dose, shows preferable preventive effect.During dispenser, poisoning generation is found no, it is right
Crop safety.
As shown in Table 8,3 days after medicine, Biphenthrin and the preventive effect of Rynaxypyr complex preparation embodiment 1 ~ 15 are
88.92% ~ 94.04%, 100 g/l of Biphenthrin missible oil preventive effects of comparison medicament are 74.38%, 200 g/l of chlorine worm benzene of comparison medicament
The preventive effect of formamide suspending agent is 78.28%, and Biphenthrin is higher than comparison medicament list with Rynaxypyr complex preparation preventive effect
Agent, show preferable quick-acting.7 days after medicine, all pharmacy control efficacies increase, wherein Biphenthrin and chlorine worm benzoyl
The preventive effect of amine complex preparation embodiment 1 ~ 15 is 91.96% ~ 96.19%, and 100 g/l of Biphenthrin missible oil preventive effects of comparison medicament are
78.23%, the preventive effect of 200 g/l of Rynaxypyr suspending agents of comparison medicament is 81.45%, Biphenthrin and chlorine worm benzoyl
Amine complex preparation preventive effect is higher than comparison medicament single dose, shows preferable preventive effect.During dispenser, poisoning generation is found no, it is right
Crop safety.
In summary, Pesticidal combination Biphenthrin of the present invention compounds with Rynaxypyr, to corn/corn
Snout moth's larva, lichee/base of a fruit moth, looper, poison moth have significant synergistic effect, can reduce dosage, delaying drug resistance, to crop safety,
Environmental security.
