Description
Technical field
The invention belongs to technical field of pesticide combination, and in particular to a kind of pesticide synergistic group containing phenthoate dimephenthoate cidial and Diacloden
Compound and its application for preventing and treating crop pest.
Background technology
Phenthoate dimephenthoate cidial (phenthoate), molecular formula:C12H17O4PS2, chemical name:O, O- dimethyl-S- (α-ethyoxyl
Carbonyl benzyl) phosphorodithioate, its mechanism of action is the acetylcholinesterase in suppression insect bodies.Phenthoate dimephenthoate cidial is a kind of high
Effect, broad spectrum activity organophosphor desinsection, ovicidal, acaricide, have and tag and stomach poison function, no systemic action.In addition, also there is residual effect
The characteristics of phase is long, quick-acting is strong, to crop safety.Available for preventing and treating rice, cotton, vegetables, citrus, fruit tree, tealeaves, oil plant etc.
The various pests such as the pink rice borer of crop, striped rice borer, yellow rice borer, leafhopper, plant hopper.Suitable for crops such as rice, cotton, fruit tree, vegetables.
Diacloden, English common name:Thiamethoxam, chemical name:3- (the chloro- 1,3- thiazoles -5- ylmethyls of 2-) -5-
Methyl isophthalic acid, 3,5- oxadiazines -4- bases fork (nitro) amine, is white crystal.Diacloden is that a kind of second generation of brand new is saline and alkaline
Class high-efficient low toxicity insecticide, there is stomach toxicity to insect, tag, Inner suctions effect, have the characteristics that work fast, lasting period are long.
Diacloden can effectively prevent and treat Lepidoptera, coleopteran pest, such as various aphids, leafhopper, aleyrodid, plant hopper, thrips, scale insect, yellow bar
Flea beetle etc., especially there is special efficacy to aphid, plant hopper etc., available for rice, tea tree, flowers, potato, vegetables, cotton, fruit tree etc.
Crop.
Use of the single dose in cultural control, often in the presence of many defects, long-term a large amount of single uses, it can make unavoidably

Embodiment
With reference to embodiment and application, the present invention is further illustrated, and the percentage in embodiment is weight hundred
Divide ratio, but the invention is not limited in this.
Unless otherwise indicated, percentage described in following embodiments is weight percentage.
First, indoor bioassay
For trying insect:The small chinch bug of cotton
Reagent agent:Phenthoate dimephenthoate cidial, Diacloden, had respectively by Jiangsu Tenglong Biological Pharmaceutical Co., Ltd. and Zhejiang grass science and technology
Limit company provides
Experimental design:
The cotton tender tip of collection is cleaned, dried, is then immersed in each concentration gradient decoction of the different ratio prepared
5s is soaked, naturally dry is taken out, is put into insect box, then connects for examination nymph, is raised under the conditions of 25 DEG C.Often handle 4 times
Repeat, often repeat test worm 10 used, while set blank control.Death toll is checked after 72 hours, and calculates the death rate and correction
The death rate.
Corrected mortality is converted into probit value (y), concentration for the treatment of (mg/L) is converted into logarithmic form, tries to achieve toxicity regression
Equation simultaneously calculates LC50Value.Then, co-toxicity coefficient CTC is calculated according to Sun Yun Liubang's formula.Wherein, CTC < 80 are antagonism,
80≤CTC≤120 are summation action, and CTC > 120 are synergistic effect.Calculation formula it is following (using phenthoate dimephenthoate cidial as standard agent, its
100) toxicity index is:
TI × P of M theoretical toxicity index (TTI)=phenthoate dimephenthoate cidialPhenthoate dimephenthoate cidialTI × P of+DiaclodenDiacloden
In formula:
M is the mixture of different ratio
PPhenthoate dimephenthoate cidialFor phenthoate dimephenthoate cidial shared ratio in the composition
PDiaclodenFor Diacloden shared ratio in the composition
As a result it is described in table 1 below.
Toxicity test of the phenthoate dimephenthoate cidial of table 1 with Diacloden different ratio to the small chinch bug of cotton
Phenthoate dimephenthoate cidial is tested the small chinch bug Toxicity Determination of cotton with Diacloden and compounding and found, when phenthoate dimephenthoate cidial and thiophene worm
Piperazine proportioning is 5:1 to 12:Co-toxicity coefficient is all higher than 120 when 1, indicates obvious synergistic effect, when the two proportioning is 7:1 to 9:
When 1, synergistic effect substantially protrudes;Especially when the ratio of phenthoate dimephenthoate cidial and Diacloden is 7:When 1, co-toxicity coefficient is maximum, synergistic effect
It is the most obvious.It can be seen that phenthoate dimephenthoate cidial:Diacloden is 5:1 to 12:There is synergistic function to the small chinch bug of cotton between 1.
