Description

一种杀菌化合物、杀菌剂组合物和制剂及其应用 技术领域
本发明涉及农用杀菌剂领域,具体地说,涉及具有杀菌活性的化合物、以所述化合物为活性成分的杀菌剂组合物和制剂及其应用。
背景技术
黄瓜霜霉病,俗称“跑马干”、“干叶子”,苗期成株都可受害,主要危害叶片和茎,卷须及花梗受害较少。黄瓜霜霉病是保护地黄瓜栽培中发生最普遍、危害最严重的病害。病情来势猛,发病重,传播快,如不及时防治,将给黄瓜造成毁灭性的损失。黄瓜霜霉病病原为鞭毛菌亚门假霜霉属古巴假霜霉菌,该病菌的孢子囊靠气流和雨水传播。在温室中,人们的生产活动是霜霉病的主要传染源。黄瓜霜霉病最适宜发病温度为16-24℃,低于10℃或高于28℃,较难发病,低于5℃或高于30℃,基本不发病。适宜的发病湿度为85%以上,特别在叶片有水膜时,最易受侵染发病。湿度低于70%,病菌孢子难以发芽侵染,低于60%,病菌孢子不能产生。病菌在保护地内越冬,翌春传播,也可由南方随季风而传播来。夏季可通过气流、雨水传播。在北方,黄瓜霜霉病从温室传到大棚,又传到春季露地黄瓜上,再传到秋季露地黄瓜上,最后又传回到温室黄瓜上。病菌为活体专性寄生真菌,种子不带菌,病菌主要靠气流传播,从叶片气孔侵入。
为了有效地防治黄瓜霜霉病,需要一种对黄瓜霜霉病防治效果显著的新的杀菌化合物。

试验方法:采用孢子悬浮液喷雾接种法测定药剂的生物活性。选择1叶1心期(摘去生长点)长势一致的盆栽黄瓜苗,药剂喷雾处理后自然晾干,24h后用毛笔蘸取蒸馏水洗取病叶背面孢子,配成孢子悬浮液(2-3×105个/ml),用接种喷雾器(压力0.1MPa)将孢子悬浮液均匀喷洒于黄瓜叶片上,然后将接种后黄瓜苗移至人工气候室内(相对湿度为100%,温度为20℃,光暗周期为(14h/10h)培养。24h后维持相对湿度90%左右保湿诱发,5d后视空白对照发病情况进行分级调查,按病指计算防效%。
调查方法和分级标准:
0级:无病;
1级:病斑面积占整片叶面积的5%以下;
3级:病斑面积占整片叶面积的6%-10%;
5级:病斑面积占整片叶面积的11%-25%;
7级:病斑面积占整片叶面积的26%-50%;
9级:病斑面积占整片叶面积的50%以上。
药效计算:
病情指数=∑(各级病叶数×相对级数值)×100/(总叶数×9);
防治效果(%)=(对照病情指数-处理病情指数)×100/对照病情指数。
