Description
技术领域
本发明属于农药研发技术领域，具体涉及一种防治茭白锈病的生物农药组合物。
背景技术
茭白是我国第二大水生蔬菜，也是我国特有的蔬菜。茭白锈病是由担子菌亚门真菌茭白冠单胞锈菌(Uromyces coronatus)侵染所致，是茭白生产上的主要病害。茭白锈病主要危害茭白叶片，遇到个发病严重的情况，甚至会导致全叶枯黄，并且结出来的茭非常瘦小，对茭白的产量危害较大。有数据显示，茭白叶片发病率可达70％以上，产量损失可达15-30％。
多年连续种植单一的茭白品种，造成茭白锈病频繁暴发，在尚无优良抗病品种的情况下，化学防治仍是控制该病流行的主要途径，常用化学药剂有25％吡唑醚菌酯水分散粒剂、10％苯醚甲环唑水分散粒剂和12.5％烯唑醇可湿性粉剂等。施用化学药剂是防治植物病虫害最为有效的手段之一，然后通过化学药剂防治病虫害容易使病虫害产生抗药性，同时长期连续高剂量地施用单一化学药剂还容易造成药剂的残留和环境污染等一些列问题。这也使得现有多种化学药剂对茭白锈病的防治效果逐年降低，因此有必要开发新型药剂来提高对茭白锈病的防治效果，保证茭白的产量和质量。
将不同成分化学药剂进行复配，根据实际应用效果来判断某种复配是增效、相加还会拮抗。其中，复配增效很好的配方，由于明显提高了实际防治效果，降低农药的施用剂量，可以大大延缓病虫害抗药性的产生，是开发新型药剂行之有效的方法之一。
生物农药是指利用生物活体或其代谢产生针对农业有害生物进行灭杀或抑制的制剂，包括植物源农药、动物源农药和微生物源农药。香芹酚(carvacrol)是由黄花香蕾经提取加工而成的一种纯植物源杀菌剂，具有较强的抗菌作用，能有效抑制病原菌孢子和菌丝的生长，具有安全、环保和无药害的有点，同时对白粉病、锈病和霜霉病等多种真菌病病害具有较好的防治效果。申请号CN201510084511.0，公开了一种含戊苯吡菌胺和香芹酚的杀菌组合物及其用途，具体公开了戊苯吡菌胺和香芹酚复配后对小麦、果树、花卉和蔬菜发生的白粉病或锈病具有良好的防治效果。
发明人通过室内生物活性试验发现香芹酚与硅噻菌胺、烯唑醇或多菌灵复配后，对防治茭白锈病表现为增效作用。目前，还尚未见有香芹酚与硅噻菌胺、烯唑醇或多菌灵复配的相关报道。
发明内容
本发明的目的在于提供一种防治茭白锈病的生物农药组合物，其可以提高对茭白锈病的防治效果，减少农药的施用剂量，延缓病原菌抗药性的产生，可以用于开发新型药剂。
为实现上述目的，本发明提供了如下技术方案：
一种防治茭白锈病的生物农药组合物，其有效成分由香芹酚与硅噻菌胺、烯唑醇或多菌灵二元复配而成。
作为优选，所述香芹酚和硅噻菌胺的质量比为1-5：7-1。
作为优选，所述香芹酚和烯唑醇的质量比为1-9：20-1。
作为优选，所述香芹酚和多菌灵的质量比为1-40：15-1。
本发明的另一个目的在于提供一种生物农药制剂，其包括所述的防治茭白锈病的生物农药组合物，其余为农药学上可添加的辅助成分。
与现有技术相比，本发明具有如下有益效果：
(1)本发明的生物农药组合物中有效成分丁香酚与硅噻菌胺、烯唑醇或多菌灵复配后对茭白锈病具有协同增效作用，可以提高茭白锈病的防治效果，有助于减少农药施用剂量，减少防治成本，降低茭白中的农药残留。
(2)本发明的生物农药组合物中有效成分丁香酚与硅噻菌胺、烯唑醇或多菌灵的杀菌机理不同，可以有效延缓病原菌抗药性的产生，延长药剂的使用寿命，可以用于开发新型药剂。
具体实施方式
根据下述实施例，可以更好地理解本发明。然而，本领域的技术人员容易理解，实施例所描述的内容仅用于说明本发明，而不应当也不会限制权利要求书中所详细描述的本发明。
实施例：香芹酚复配对茭白锈病的室内生物活性试验
1.供试菌株：茭白冠单胞锈菌新鲜夏孢子，采自染病茭白植株。
2.供试药剂
92.5％香芹酚原药(上海源叶生物科技有限公司)；
98％硅噻菌胺原药(河北兴柏农业科技有限公司)；
95％烯唑醇原药(江苏七洲绿色化工股份有限公司)；
98％多菌灵原药(江苏辉丰生物农业股份有限公司)。
将上述供试药剂先用二甲基亚砜溶解，再用0.1％吐温-80水溶液稀释配制成单剂母液，设置多组配比，各单剂和配比混剂均按等比方法设置5个质量浓度梯度。
3.试验方法(参考《NY/T 1156.1-2006农药室内生物测定试验准则杀菌剂第1部分：抑制病原真菌孢子萌发试验凹玻片法》)。
采集染病茭白植株上的新鲜夏孢子，用去离子水将孢子重悬浮至每毫升1×105个至1×107个孢子，并加入0.5％葡萄糖溶液。
用移液管从低浓度到高浓度依次吸取药液0.5mL分别加入小试管中，然后吸取制备好的孢子悬浮液0.5mL，使药液和孢子悬浮液等量混合均匀。用微量加样器吸取上述混合液滴到凹玻片上，然后架放于带有浅层水的培养皿中，加盖置于25℃培养箱中。每个处理设置3次重复，并设0.1％吐温-80水溶液的处理作为空白对照。
当空白对照孢子萌发率达到90％以上时，检查和处理孢子的萌发情况。每处理各重复随机观察3个视野，调查孢子总数200个，分别记录萌发数和孢子总数，其中孢子牙管长度大于孢子的短半径视为萌发。根据调查数据，计算各处理的孢子萌发相对抑制率。
4.数据分析：采用DPS软件进行数据统计分析，以杀菌剂浓度对数值为x，对应的孢子萌发相对抑制率几率值为y进行线性回归，得出毒力回归方程及药剂对靶标病菌的毒力EC50值，并根据孙云沛法计算共毒系数(CTC)。
上式中：ATI--混剂实测的毒力指数；S--标准药剂的EC50，单位为mg/L；M--混剂的EC50，单位为mg/L。
TTI＝TIA×PA+TIB×PB
上式中：TTI--混剂的理论毒理指数；TIA--A药剂的毒力指数；PA--A药剂在混剂中百分含量，单位为百分率(％)；TIB--B药剂的毒力指数；PB--B药剂在混剂中百分含量，单位为百分率(％)。
上式中：CTC--共毒系数；ATI--混剂实测毒力指数；TTI--混剂理论毒力指数。
5.测定结果
根据计算的共毒系数(CTC)评价药剂的增效作用，CTC≤80为拮抗作用，80＜CTC＜120为相加作用，CTC≥120为增效作用，结果见表1-3。
