Fruit.Experiment each four repetitions of processing, the random district's groups arrangement of cell processing, each plot area is 50m2, first time dispenser exists
When rice tillering latter stage infects, emphasis imposes on basal part of stem, applies a medicine again in the booting later stage, and investigation method is：According to water
Rice leaf sheath and blade damage symptom grading, in units of strain, per the 5 points of samplings of cell diagonal, every investigation is connected 5 clumps
Totally 25 clumps, record total strain number, diseased plant number and sick series.
2 benzo alkene fluorine bacterium azoles of table and pyraclostrobin and different agents are to the preventive effect of rice sheath blight disease
From above-mentioned data as can be seen that benzo alkene fluorine bacterium azoles and pyraclostrobin complex preparation before secondary medicine 1 day it is right
The preventive effect of rice sheath blight disease is more than 75%, and 14 days preventive effects to rice sheath blight disease are more than 80% after secondary medicine, compared to benzene
And two kinds of single doses of alkene fluorine bacterium azoles and pyraclostrobin, complex preparation preventive effect difference are extremely notable, it is seen that two kinds of active ingredient compoundings have
Good synergistic effect, extends the lasting period, more longlasting to the control effect of rice sheath blight disease.
According to given data and our experiments demonstrated that, benzo alkene fluorine bacterium azoles and pyraclostrobin be configured to suspending agent and
After water dispersible granules (example 12 and example 13), to aquatile high poison, without being suitably applied on rice, but the present invention answers
Preparaton (1~example of example 11) is handled since active ingredient has been carried out good microencapsulation, to the toxicity of aquatile by
High poison changes into low toxicity, to aquatile safety.Complex preparation is shown in Table 3 to the acute toxicity data of fish.
3 complex preparation of table is to the acute toxicity data of fish
| Processing | Lethal concentration of 50 LC50 (mg/L) |
| Example 1 | 13.5 |
| Example 3 | 12.1 |
| Example 5 | 11.9 |
| Example 7 | 12.2 |
| Example 12 | 0.89 |
| Example 13 | 0.82 |
In conclusion complex preparation can be very good to improve the security of product, overcome and aquatile high poison is lacked
Point can apply controlling disease in rice, improve drug effect, extend the lasting period, mitigate the amount of labour of peasant, there is very high practicality
Property.
