| 摘要: |
| 近年来水稻恶苗病严重威胁着汉中地区的水稻生产。试验证明:致病菌主要是念珠镰刀菌,稻种带菌率高,带菌量大,稻种带菌率与田间发病率相关关系显著。以种子带菌为本病主要传播途径。用0.04—0.05％的“402”,或0.1—0.05％的多菌灵,或2％的福尔马林进行种子处理,能有效地防治此病.用石灰水、温水、硫酸铜等方法浸种,防治效果较差,且不稳定。 |

| Abstract: |
| In resent years Bakanae disease of rice has become an important problem in rice production in Hanzhong prefecture.Experimints have proved that the main pathogen inducing Bakanae desease in Hanzhong prefecture is Fusarium moniliforme,which is mainly transmitted by seed.So,detecting the seed-borne pathogen in rice isbased on the microconidium of Fusarium moniliform.Interrelations between the seed-borne pathogen and the infected plant in the field is very conspicuous.Carrying out seed treatment with 0.04-0.05％ antibiotic "402",0.10-0.05％ Bavitin or 2％ Formalin may effectively protect the rice plant from Bakane diease.The effect of soaking seeds in limewater,hot water or cupric sulphate to control this disease is very low and unstable. |
