用防治真菌种传病害的浸种剂 2 5 %施保克乳油、2 5 %使百克乳油和防治线虫的浸种剂 95 %巴丹可溶性粉剂及兼治真菌和线虫种传病害的 16 %恶线清可湿性粉剂、4 .2 %浸丰乳油分别对带线虫的武育粳 3号、镇稻2号及武运粳 7号种子进行浸种处理后播种 ,试验结果表明 :使用防治线虫的浸种剂可以有效地控制水稻“小穗头”现象的发生。经南京农业大学植物保护学院线虫实验室鉴定 ,来自武育粳 3号、武运粳 8号的“小穗头”和武运粳 7号小穗发病田混收稻谷内的线虫为干尖线虫。用 95 %巴丹可溶性粉剂、16 %恶线清可湿性粉剂、4 .2 %浸丰乳油、2 5 %使百克乳油浸种及清水对照的田间“小穗头”发生率分别为 0 .31%、1.34%、1.78%、4 4 .0 %和35 .71% ,4种浸种药剂对“小穗头”的防治效果依次为 99.10 %、96 .90 %、95 .90 %和 - 17.8% ;具有防治线虫作用的浸种剂巴丹、恶线清和浸丰对“小穗头”的防治效果较好 ,浸种剂 2 5 %施保克乳油及 2 5 %使百克乳油等咪鲜胺类制剂对由干尖线虫造成的水稻“小穗头”没有防治效果
25% Schiphol EC, 25% EC and 95% Baptist Soluble Powder and 16% Malodor Residue which can cure fungal and nematode diseases. Wettable powder and 4.2% Baptist emulsifiable solution were sowed and soaked in seeds of nematodes Wuyujing 3, Zhenjiang 2 and Wuyunjing 7, respectively. The results showed that: Effectively control the occurrence of rice “small spike head” phenomenon. The nematodes collected from the nematode laboratory of Nanjing Agricultural University were identified as “Apocynum” by Wuyujing 3 and Wuyunjing 8, . The incidence of “spikelet” in field with 95% Bardan soluble powder, 16% virgin WP, 4.2% Baptist emulsifiable concentrate, 25% Bark soaking and clear water control were 0.31 %, 1.34%, 1.78%, 44.04% and 35.71%, respectively. The control effect of 4 kinds of soaking agents on the spikelet was 99.10%, 96.90%, 95.90% and -17.8% ; The soaking agent with nematode effect, Badan, Yaoxianqing and Baptist, had better control effect on “small spike head”, the soaking agent 25% Shibakai EC and 25% The preparation has no control effect on the rice “small spike head” caused by the tip-tip nematode
