Study on Field Efficacy of 0.3% Polyoxin against Rice Blast |
|
| Abstract: | Objective] The research aimed to popularized 0.3% Polyoxin.Method] The controling-test with 0.3% polyoxin was carried out at the zone that the rice blast occurred often in Cenxi city,Guangxi province.Result] No obvious phytotoxicity was observed after bactericide application.The control effect of 3 000 ml/hm2 and 2 250 ml/hm2 0.3% Polyoxin were 87.92% and 87.33% for leaf blast,and 91.17% and 91.15% for spike blast,respectively.The two treatments had no obvious difference,but both were significantly higher than that of 6% kasugamycin WP 700 g/hm2.Conclusion] With the advantages of good safety and control effect,0.3% polyoxin could be generalized in field,and the propositional using dosage was 2 250-3 000 ml/hm2. |
