Description

番茄灰霉病的防治药剂
技术领域
本发明涉及一种番茄灰霉病的防治药剂，属于生物制剂领域。
背景技术
番茄在生长过程中容易受到各种病害侵染，长期以来，化学防治是主要防治手段。近年来，由于单一用药和不规范用药，已经导致许多病害产生抗药性，如灰霉病等，已经成为化学防治的一大难题。同时，频繁用药又造成农民用药成本的增加和环境污染的加剧，作物中农药残留严重，不利于人们的身体健康。
发明内容
为了解决上述技术问题，本发明提供一种番茄灰霉病防治药剂，属于纯中药制剂，防治效果好，无残留。
为了实现上述第一目的，本发明的技术方案如下：一种番茄灰霉病防治药剂，其特征在于：有效成分由重量份数的以下中草药的提取液和油菜素内酯、三十烷醇的混合物组成，
所述中草药为:苦参2-3份，蛇床子1-4份，百部3-5份，土茯苓3-5份，地肤子5-7份，龙胆草4-8份，苦楝5-8份；
将上述中草药粉碎，每次加3-5倍水在温度95-100℃下混合提取三次，每次1-1.5h，合并提取液；
将所得的提取液冷却至室温，按照重量份数，提取液80-120份，加入油菜素内酯0.0002-0.006份、三十烷醇0.0002-0.006份得到番茄灰霉病防治药剂。
上述方案中：提取液中还加有有机硅增效剂。
优选：所述有机硅增效剂为Silwet L-77。增强药液在植物表面的润湿、粘附及展开能力，从而提高药效。
优选：按照重量份数，所述有机硅增效剂的量为3-6份。
本发明中：油菜素内酯是一种新型植物内源激素，是第一个被分离出的具有活性的油菜素甾族化合物(Brassinosteroids，BRs)，是国际上公认为活性最高的高效、广谱、无毒的植物内源生长激素。
三十烷醇具有促进生根、发芽、开花、茎叶生长和早熟作用，具有提高叶绿素含量、增强光合作用等多种生理功能。在作物生长前期使用，可提高发芽率、改善秧苗素质，增加有效分蘖。在生长中、后期使用，可增加花蕾数、座果率及干粒重。
本发明将具有杀菌抑菌效果的中草药提取液与存在于植物体内始终左右着植物生长全过程的基因诱导物质油菜素内酯和三十烷醇复配，协同使用，增强防病、增产效果，能预防和控制番茄灰霉病的发生和发展。
本发明在番茄灰霉病发病初期施用，第一次喷雾后，间隔一星期左右再喷雾一次，喷雾时稀释500-1000倍。
试验证明它对番茄灰霉病防治效果高达95％以上，同时可使番茄产量提高20-28％，本发明为绿色制剂，不存在农药残留，无污染。
具体实施方式
下面结合实施例对本发明作进一步说明：
实施例1

按照重量份数取中草药为:苦参2份，蛇床子1份，百部3份，土茯苓3份，地肤子5份，龙胆草4份，苦楝5份。
将上述中草药粉碎，每次加3倍水在温度95-100℃下混合提取三次，每次1-1.5h，合并提取液。
将所得的提取液冷却至室温，按照重量份数，提取液80份，加入油菜素内酯0.0002份、三十烷醇0.0002份，有机硅增效剂Silwet L-77 3份混合得到。
实施例2
番茄灰霉病防治药剂，制备方法为：
按照重量份数取中草药为:苦参3份，蛇床子4份，百部5份，土茯苓5份，地肤子7份，龙胆草8份，苦楝8份。
将上述中草药粉碎，每次加5倍水在温度95-100℃下混合提取三次，每次1-1.5h，合并提取液。
