Abstract
本发明涉及用于控制或预防植物被壳球孢属物种的植物病原性微生物侵染的方法,所述方法包括向植物作物、其场所或其繁殖材料施用根据式(I)的化合物,其中R1、R2、R3、R4、R5、Y、A、B是如本文所定义的。
Description
技术领域
本发明涉及用于控制或预防植物被壳球孢属物种的植物病原性微生物侵染的方法。
背景技术
壳球孢属物种是感染超过100个科的近500种植物物种的真菌。
该病原体影响其宿主的根和基部节间的维管系统,阻断水和营养物向植物上部部分的运输。其结果是,逐渐枯萎、过早死亡、失去活力和减产是感染的特征性症状。该真菌还引起许多疾病,像立枯病、苗枯病、颈腐病、茎腐病、炭腐病、茎基腐病和根腐病。
本发明提供了用于控制或预防植物被壳球孢属物种的植物病原性微生物侵染的进一步改进的方法。
具体实施方式
在WO 2013/143811和WO 2015/003951中披露了环丁基甲酰胺化合物及其制备方法。现已出人意料地发现,在WO 2013/143811和/或WO 2015/003951中披露的特定环丁基甲酰胺化合物在控制或预防植物被壳球孢属物种的植物病原性微生物侵染方面非常有效。因此,这些非常有效的化合物为农民控制或预防植物被壳球孢属物种的植物病原性微生物侵染提供了重要的新解决方案。
因此,如实施例1,提供了控制或预防植物被壳球孢属物种的植物病原性微生物侵染的方法,所述方法包括向植物作物、其场所或其繁殖材料施用根据式(I)的化合物
其中
Y是O、C=O或CR12R13;
A是5元或6元杂芳香族环或苯环,所述杂芳香族环含有各自独立地选自氧、氮和硫的1至3个杂原子;所述杂芳香族环或所述苯基任选地被一个或多个R6取代;

生物学实例
不同杀真菌剂处理对壳球孢属物种的作用
在温室美国维洛海滩(Vero Beach,United States)进行了草莓盆栽试验,以评估不同化合物对菜豆壳球孢菌的功效。
将植物种植在具有Vero Beach Mix(50%盆栽介质和50%巴氏灭菌沙)的4L盆中。植物是品种为‘Sweet Ann’的裸根草莓。草莓植物被部分种植,然后用2克被侵染的粟进行接种。接种物在经过两次灭菌的粟上生长1-2周。使用的分离物是最初从草莓中分离的。接种后,根被完全覆盖。在种植当天,每株植物浸灌施用100mL的化合物溶液。施用剂量是基于30.5cm乘以45.7cm的植物间距计算的。植物在平均白天32℃且夜晚21℃的温室中生长。每天给植物浇水。施用后44天和65天后,使用IS 0-5指数等级(5=严重损害,0=无损害)评估病害严重程度。
