Description

一种防治水稻稻瘟病的植物源杀菌剂
技术领域
本发明属于农药技术领域,具体涉及一种防治水稻稻瘟病的植物源杀菌剂。
背景技术
稻瘟病是水稻重要病害之一，可引起大幅度减产，严重时减产40～50％，甚至颗粒无收。世界各稻区均有发生，其中以叶部、节部发生为多，发生后可造成不同程度减产，尤其穗颈瘟或节瘟发生早而重，可造成白穗以致绝产。近年来，广东稻瘟病年发生面积不少于50万亩，而且出现逐年增加趋势，局部大爆发并不少见，目前，稻瘟病可能发生在省域内的任何年头、任何季节。主要危害叶片、茎秆、穗部。因危害时期、部位不同分为苗瘟、叶瘟、节瘟、穗颈瘟、谷粒瘟。苗瘟发生于三叶前，由种子带菌所致，病苗基部灰黑，上部变褐，卷缩而死，湿度较大时病部产生大量灰黑色霉层，即病原菌分生孢子梗和分生孢子。叶瘟在整个生育期都能发生，分孽至拔节期危害较重。节瘟常在抽穗后发生，初在稻节上产生褐色小点，后渐绕节扩展使病部变黑，易折断，发生早的形成枯白穗，仅在一侧发生的造成茎秆弯曲。穗颈瘟初形成褐色小点，放展后使穗颈部变褐，也造成枯白穗；发病晚的造成秕谷，枝梗或穗轴受害造成小穗不实。谷粒瘟产生褐色椭圆形或不规则斑，可使稻谷变黑；有的颖壳无症状，护颖受害变褐，使种子带菌。常用的药剂春雷霉素，甲基硫菌灵、三环唑已多年使用，已产生抗性，防治水稻稻瘟病不理想。
发明内容
针对上述，本发明的目的是提供一种防治水稻稻瘟病的植物源杀菌剂。
本发明采取的技术方案是：
一种防治水稻稻瘟病的植物源杀菌剂，由以下重量份原料制成：木姜子7-9份、山苍子2-3份、绵马贯众3-5份、苍耳草6-8份、生地黄2-3份、侧伯叶5-7份、肉桂3-5份、绞股蓝6-9份、紫茎泽兰5-8份、茜草5-8份、增效剂1-3份。
优选地，所述的植物源杀菌剂，由以下重量份原料制成：木姜子8份、山苍子2.5份、绵马贯众4份、苍耳草7份、生地黄2.5份、侧伯叶6份、肉桂4份、绞股蓝7.5份、紫茎泽兰6.5份、茜草6.5份、增效剂2份。
进一步地，所述的增效剂为脱乙酰壳多糖或壳寡糖。
进一步地，所述的植物源杀菌剂的制备方法是：将上述除增效剂以外的原料晾干粉碎，在乙醇中浸泡3-6小时，进行循环提取3-4次，每次提取50-60分钟，合并提取液，将提取液置于旋转蒸发仪中真空浓缩，浓缩液中加入增效剂，搅拌均匀即得植物源杀菌剂。
本发明的优点是：本发明杀菌剂配伍科学合理，具有杀菌广普、见效快、持效时间长，不会产生抗药性等优点，且可在自然界降解，来源于自然，不会污染环境及农产品，在环境和人体中不会形成积累毒性，对人和牲畜相对安全。
