Embodiment
Essence for a better understanding of the present invention, is described further with reference to embodiment to present disclosure,
But limitation of the present invention can not be considered as, it is as described below to be only used for explaining the present invention, for without departing from spirit of the invention and principle
Modification, replacement or the improvement made, belong to the scope of protection of present invention.
The synergistic function of the present composition can pass through following experiment explanation：
Embodiment one：Probenazole and fluopyram combination are tested the toxicity test of watermelon root-knot.
Evaluation method is pot-culture method.From the pieces of an egg sterile water wash of picking root-knot nematode on watermelon root, culture dish is placed in
Wet filter paper on, add 20ml sterilized waters, hatch at 20 DEG C -25 DEG C, obtain age consistent 2 instar larvaes, diluted with sterilized water
To 200/ml.2 instar larvaes are inoculated with the leaf phase of watermelon two, using root injection method, take 5ml nematodes inoculation liquid to inject rhizosphere soil
It is interior, 24h soil conservations 70%-80% humidity after inoculation.It is standby after watermelon inoculation root-knot nematode.
Active component is made into mother liquor after dissolving on request, suitable concentration is then diluted to purified water carries out root irrigation.
Watermelon seedling is placed in phjytotron after chemicals treatment, then 25-30 DEG C, 12h alternation of light and darkness, relative humidity 35%-
30d is cultivated under the conditions of 50%.Each to repeat the basin of random searching 4, each processing amounts to 16 basin watermelons of investigation.
Grade scale presses National Standard of the People's Republic of China《Pesticide field efficacy medicine test criterion (one)》, severity Scaling mark
It is accurate.
Diseased plant stage division is as follows:
0 grade:Root system is without insect gall；
1 grade:Root system has a small amount of small insect gall；
3 grades:2/3rds root systems are covered with small insect gall；
5 grades:Root system is covered with small insect gall and has secondary insect gall；
7 grades:Root system formation fibrous root group.
Computational methods：
Root knot index=∑ (diseased plant numbers at different levels × relative series)/investigation total strain number × 7 × 100
Prevention effect (%)=(control disease index-processing disease index)/control disease index × 100
Statistical analysis is carried out with DPS statistical analysis softwares, the LC of each medicament is calculated50, and mixture is calculated according to the abundant methods of Sun Yun
Co-toxicity coefficient (CTC values).
Survey toxicity index (ATI)=(standard agent LC50/ reagent agent LC50)×100。
A percentage composition+B medicament toxicity index in theoretical toxicity index (TTI)=A medicament toxicity index × mixture × mixed
B percentage composition in agent.
Co-toxicity coefficient (CTC)=[mixture actual measurement toxicity index (ATI)/mixture theoretical toxicity index (TTI)] × 100.
The Co-toxicity criteria for classifying：Co-toxicity coefficient (CTC) >=120 shows as synergistic effect；Co-toxicity coefficient (CTC)≤80 table
It is now antagonism；80 ＜ co-toxicity coefficients (CTC) ＜ 120 show as summation action.

Amine is 40:1~1:In the range of 1, synergistic function is more notable, and co-toxicity coefficient (CTC) is more than 160；Phenyl allyloxy thiophene
Azoles and fluopyram are with 5:1 (pressing quality) compounding, synergistic function is the most notable, and co-toxicity coefficient (CTC) is 192.1.Can
See, probenazole and fluopyram combination have reasonability and feasibility.
Embodiment three：Probenazole and fluopyram combination are tested powdery mildew of cucumber toxicity test.
By probenazole, fluopyram and combinations thereof medicament, weigh medicament and addition adds going out for good 2mL acetone in advance
In bacterium triangular flask, fully shaking dissolves it, then adds sterilized water that experiment mother liquor is made standby.On the basis of pilot study,
The mother liquor configured is diluted to 5 concentration gradients from high to low by concentration respectively.
The cucumber seedling in potted plant 20 days growth periods is selected, in powdery mildew early period of origination cauline leaf spray-on process dispenser (with blade surface
There is water membrane to be advisable), spray apparatus uses hand sprayer (liquid capacity about 2.0L), every 10 days sprays once, continuously
Spray 2 times.Often processing selects uniform 10 blade of morbidity as efficacy of medicine observing object, each 3 repetitions of processing.
Diseased plant stage division is as follows:
0 grade：Disease-free spot；
1 grade：Lesion area accounts for less than the 5% of whole leaf area；
3 grades：Lesion area accounts for the 6%-15% of whole leaf area；
