Biological test
1 jamaicin of embodiment and biphenyl pyrrole bacterium amine compound the Toxicity Determination to cucumber downy mildew
Subjects：Bacterium of downy mildew of cucumber
This experiment is using (the experiment reference of cucumber downy mildew potting measuring method《Pesticide bioassay technology》(old spring chief editor,
Publishing house of Beijing Agricultural University publishes) and《Farm-chemical indoor determination test rule NY/T1156.2-2006》.It is tried in preparation
On the basis of testing, 2 leaf periods, the consistent melon seedling of growing way are selected, tag number is write with permanent pen, is inserted into potting cucumber seedling
It in basin, sequentially discharges, using foliar spray method, medicament is sprayed on melon seedling blade, material will be tried after spraying treatment in draught cupboard
Or it dries in the shade in greenhouse and is inoculated with afterwards for 24 hours.7d investigation prevention effects are cultivated in the greenhouse, and control effect is calculated with disease index, uses DPS
Data processing software is for statistical analysis, calculates the EC50 of each medicament, then presses Sun Yunpei's Method and calculates co-toxicity coefficient (CTC).Tool
Body measurement the results are shown in Table 1.
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 surveys toxicity index (ATI)/mixtures theoretical toxicity index (TTI)] × 100.
The toxicity test of 1 jamaicin of table and biphenyl pyrrole bacterium amine to cucumber downy mildew
Test result shows that jamaicin and biphenyl pyrrole bacterium amine have synergistic effect to cucumber downy mildew, matches 40:1-1:
When between 40, for co-toxicity coefficient all 120.0 or more, jamaicin and biphenyl pyrrole bacterium amine are 1:5-5:When 1, co-toxicity coefficient all exists
140.0 or more, synergistic effect is notable.
Embodiment two：Jamaicin and biphenyl pyrrole bacterium amine compounding try the field efficacy of rice sheath blight disease
Five processing of experiment setting, often handle 3 repetitions.In the 1st dispenser of rice sheath blight disease early stage, after every 7d
Spray 1 time, continuous spray 2 times, 7d investigates rice sheath blight disease incidence, record diseased plant number and sick series after the 2nd dispenser,
Calculate control effect.
Test medicine：
Medicament 1：30% jamaicin biphenyl pyrrole bacterium amine suspending agent (jamaicin 10%+ biphenyl pyrrole bacterium amine 20%)
Medicament 2：40% jamaicin biphenyl pyrrole bacterium amine suspending agent (jamaicin 30%+ biphenyl pyrrole bacterium amine 10%)
Control 1：30% jamaicin wettable powder；
Control 2：25% biphenyl pyrrole bacterium amine wettable powder
2 jamaicin of table and biphenyl pyrrole bacterium amine compound the field efficacy to rice sheath blight disease
| Test medicine | Extension rate | Preventive effect (%) |
| Medicament 1 | 2000 | 87.4 |
| Medicament 2 | 2500 | 85.3 |
| Control 1 | 1000 | 66.2 |
| Control 2 | 2500 | 62.7 |
Table of field test results are bright：Jamaicin and biphenyl pyrrole bacterium amine compounding are better than list to the control effect of rice sheath blight disease
Agent has synergistic effect.The dosage that active constituent can effectively be lowered, slows down the generation of disease drug resistance.
