稻曲病又名绿穗病、谷花病、开花米,在我国及日本又称其为“丰收病”。稻曲病不仅影响产量,且因病菌含对人、畜、禽有毒物质及致病色素C_9H_6O_7。用混有0.5%以上的病谷喂猪后,肉猪生长、增重速率下降;母猪产死胎,畸形胎,仔猪成活降低。对人的健康也有不良影响。 1、稻曲病的危害症状稻曲病在开花后至乳熟期发生,只为害谷粒。每穗上的病谷少则1～2粒,多的可达40～50粒。病菌在颖壳内生长,初时受侵害谷粒颖壳稍张开,露出黄绿色的小型块状突起,后逐渐膨大,包裹全颖,渐变为绿色后龟裂,散布出黑绿色粉末,即病菌的厚垣孢子。厚垣孢子粉状,略带粘性,不易飞散,但可借气流传播,在水稻子开花时侵染
False Smut is also known as the “green ear” disease, valley disease, flowering rice, also known as “harvest disease” in our country and Japan. False Smut affects not only yield, but also pathogens that contain toxic substances and pathogenic pigments C_9H_6O_7 to humans, livestock and poultry. Pig mixed with more than 0.5% sick pigs, pig growth, weight loss rate decreased; sow stillbirth, deformity of the fetus, piglets survival decreased. On human health also have a negative impact. 1, the damage symptoms of false smut The smut disease occurs after flowering to milk ripening, only to damage the grain. Diseases of the panicle on each spike from 1 to 2, up to 40 to 50 more. The germs grow in the glume shell. At first, the glume shell of the gluten shell slightly opened exposing the yellow-green bulky bulge, and gradually enlarged, wrapped all Ying, gradually changed into green after the crack, scattered black-green powder, that is, germs Chlamydospores. Chlamydospore powdery, slightly viscous, not easy to fly, but can be spread by air flow, infested in rice flowering
