Specific embodiment
The specific embodiment of the present invention is described in detail with reference to embodiment, it is to be understood that the guarantor of the present invention
Shield range is not restricted by specific implementation.
Biological activity determination
Experiment one：Folpet and penflufen-containing compound the toxicity test to pepper anthracnose
Subjects：Colletotrichum capsici
Test method：It is measured using growth rate method.Under aseptic technique, the sterilising medium melted in advance is determined
Amount is added in sterile conical flask, is quantitatively drawn liquid successively from low concentration to high concentration, is separately added into above-mentioned conical flask, fully
It shakes up.Then equivalent is poured into the culture dish that 3 diameter above are 9cm, and the drug containing tablet of respective concentration is made.It will be cultured
Pathogen, aseptically with the sterilization punchers of diameter 7mm, bacteria cake is cut from colony edge, is connect bacteria cake with inoculator
For kind in drug containing tablet center, mycelia is face-up, covers ware lid, puts in 26 DEG C of insulating boxs and cultivates.Bacterium colony is measured with crossing method
Diameter, it is for statistical analysis to data.It is for statistical analysis with DPS data processing softwares, the EC50 of each medicament is calculated, is then pressed
The abundant methods of Sun Yun calculate co-toxicity coefficient (CTC).
When CTC≤80, then composition shows as antagonism, and as 80 ＜ CTC ＜ 120, then composition shows as being added and make
With when CTC >=120, then composition shows as synergistic effect.
Survey toxicity index (ATI)=(standard agent EC50/ reagent agent EC50) × 100
Percentage composition+B the medicament toxicity index of A in theoretical toxicity index (TTI)=A medicament toxicity index × mixture × mixed
The percentage composition of B in agent
Co-toxicity coefficient (CTC)=[mixture actual measurement toxicity index (ATI)/mixture theoretical toxicity index (TTI)] × 100.
1 folpet of table and penflufen-containing are to the toxicity test of pepper anthracnose
As seen from the above table, folpet and penflufen-containing are 1:70-70:Pepper anthracnose is not gone out in 1 ratio range
Existing antagonism, shows as addition or synergistic effect；When folpet and penflufen-containing weight ratio are 1:25-50:When 1, it is total to
Malicious coefficient shows as synergistic function all more than 120.0.
Experiment two：Folpet and penflufen-containing compound the field efficacy to pepper anthracnose
Test method：First each processing liquid weighing is matched before experiment, blank district is first sprayed, then successively with clear water
Each treatment region liquid of even spraying.Trial zone 1d before dispenser investigates disease index radix, and 10d carries out control effect after dispenser
Investigation, investigation method are investigated using method of random sampling.5 plants are taken at random per cell, and 2 branch numbers of often selecting good strains in the field for seed are listed, before medicine
All from the full lamina of branch point, 30 leaves of number carry out morbidity series investigation down after medicine, 300 leaves are investigated per cell, often processing investigation
1200 leaves determine onset grade, then calculate disease index and preventive effect respectively according to the occurring degree of each blade.
The grade scale of pepper anthracnose：0 grade, disease-free spot；L grades, lesion area accounts for less than 2% leaf (fruit) area；3
Grade, lesion area account for the 3%-8% of leaf (fruit) area；5 grades, lesion area accounts for the 9%-15% of leaf (fruit) area；7 grades,
Lesion area accounts for the 16%-25% of leaf (fruit) area；9 grades, lesion area accounts for more than 25% leaf (fruit) area.
