Accurately take rice straw sample 20.0g, after sample is carried out extraction and purified treatment, with liquid chromatography for measuring rice stem base portion pesticide active ingredient dosage.
Rice sheath blight disease investigation standard is as follows:
3d, 7d, 14d after medicine, according to rice leaf sheath and blade damage symptom grading, in units of strain, every community diagonal 5 point sampling, often some investigation is connected 2 clumps, totally 10 clumps, records total strain number, diseased plant number and sick progression.
Grade scale
0 grade: complete stool is anosis;
1 grade: quaterfoil and following leaf sheath, blade morbidity (taking sword-like leave as first leaf);
3 grades: Three-blade and following leaf sheath thereof, blade morbidity;
5 grades: second blade and following leaf sheath thereof, blade morbidity;
7 grades: sword-like leave blade and following leaf sheath thereof, blade morbidity;
9 grades: complete stool falls ill, withered ahead of time.
Computing formula:
Table 9 is the film-spreading oil solution of film forming agent of the present invention preparation and the result of the test of the conventional water prevention rice sheath blight of spraying.
