化学诱抗剂好米得诱导水稻抗稻瘟病的田间效果

Preliminary Studies on Controlling Rice Blast with Disease-Resistant Inducing Chemicals

田间水稻经化学诱抗剂_____好米得处理后 ,对稻瘟病具有一定抗性。好米得诱导水稻抗稻瘟病的效果与常规药剂三环唑相当 ,最高可达68.8 % ,并且不影响水稻生长发育和产量。好米得的诱导抗性是相对的、不完全的 ,只有与其他杀菌剂配合使用 。

Treated with disease-resistant inducing chemicals, Oryzemate,field rice had some resistance to rice blast,with an effect almost the same as that of tricyclazole.Rice blast resistant effect induced by Oryzemate can be as high as 68.8%.It did not make negative effect on the growth and yielding of the rice.The disease-resistance induced by Oryzemate is relative and incomplete.When used with other germicides it controls rice blast more effectively.
