Description

一种防治香蕉蓟马农药组合物 技术领域
本发明涉及农药技术领域，特别涉及一种防治香蕉蓟马农药组合物。
背景技术
香蕉黄胸蓟马(Thrips hawaiiensis)又名花蓟马，为香蕉的主要害虫之一。该虫主要以成虫在香蕉刚出蕾时，侵入蕾苞危害香蕉的幼果，造成嫩果表皮上形成木栓化、顶端褐黑色的突起斑点，严重影响香蕉果实的外观及商品价值。由于蓟马个体较小，躲藏在香蕉花蕾内危害蕉果，致使药液较难接触到虫体，再加上香蕉蓟马世代周期短、繁殖力强等特点，致使蕉农在施药过程中不断加大药剂浓度和增加施药次数来提高防治效果，一方面造成害虫抗药性加剧，另一方面造成药液的浪费和环境的污染，进而使施药者吸入、接触到大量药液，严重危害人们的身体健康。因此，减少化学农药的使用并提高防治效果具有重要意义。
d-柠檬烯，又称苎烯，是多种水果(主要为柑橘类)、蔬菜及香料中存在的天然成分，为单环单萜类化合物。大量研究发现，该化合物具有一定的抗癌、抑菌和杀虫作用。
胺鲜酯是90年代发现的具有广谱和突破性效果的高能植物生长调节剂，它能提高植物过氧化物酶和硝酸还原酶的活性，提高叶绿素的含量加快光合速度，促进植物细胞的分裂和伸长，促进根系的发育，调节体内养分的平衡。
现有技术中发现d-柠檬烯用于防治香蕉蓟马的作用，如申请号CN201811522576.9，名称为含有d-柠檬烯的增效农药组合物专利；申请号 CN201810097619.7，名称为一种生物杀虫剂及其应用，但未见胺鲜酯用于防治香蕉蓟马的报道。
发明内容
本发明发现胺鲜酯对香蕉蓟马具有防治作用，且d-柠檬烯与胺鲜酯复配，有明显的增效作用，对香蕉蓟马的防治效果优于胺鲜酯、d-柠檬烯单一成分对香蕉蓟马的防治效果。

胺鲜酯作为活性成分在防治香蕉蓟马中的应用。
与现有技术相比，本发明的有益效果为：
(1)本发明发现胺鲜酯可用于防治香蕉蓟马，其LC 50值达到47.06mg/L，对香蕉黄胸蓟马的毒力低于d-柠檬烯。
(2)本发明发现胺鲜酯对香蕉蓟马具有防治作用，且d-柠檬烯与胺鲜酯复配，对香蕉蓟马的防治效果优于胺鲜酯、d-柠檬烯单一成分对香蕉蓟马的防治效果。当所述胺鲜酯与d-柠檬烯的重量比为1：1时，有明显的增效作用；同时也降低了药剂的使用量，减少了环境污染。
(3)本发明在田间防效过程中发现花蕾注射法的防治效果明显优于传统喷雾法。
(4)d-柠檬烯与胺鲜酯的作用机制不同，可以克服长期单一使用容易产生抗药性的缺点，延长药剂的使用寿命，对害虫抗性的综合治理有着重要意义。
(5)通过本发明的助剂制作的防治香蕉蓟马农药组合物制剂都符合相关质量标准。

一、验证试验
1、实施例1对香蕉蓟马的药效试验
d-柠檬烯与胺鲜酯联合毒力测定
靶标害虫：香蕉蓟马
试验药剂：d-柠檬烯、胺鲜酯
测定方法：
采用叶管药膜法。先将10mg试验药剂用10mL丙酮溶解配成1mg/mL母液，再用清水稀释至100mg/L、50mg/L、25mg/L、12.5mg/L和6.25mg/L，保证已配好药液透明、分散均匀。在配制好药液后，首先制作离心管药膜(管壁扎有若干细孔)，取1mL药液加入管内，来回摇动直至药液在管内着药均匀，将多余药液倾出，室内自然晾干。再用相同浓度的药液浸渍香蕉花花瓣，待到药膜和浸药花瓣晾干后，将带药花瓣放入药膜管内，组成叶管药膜。最后，接入参试试虫30头，并培养观察，48h后检查试虫的存活情况，以细毛笔轻触不动为死 亡。以水膜管和浸清水的香蕉花花瓣作为对照组，每浓度处理4次重复。对照组死亡率＜10％为有效试验。
统计分析：统计各处理死虫数，并计算d-柠檬烯和胺鲜酯对香蕉蓟马的LC 50值，采用共毒系数法计算混用药剂的共毒系数(CTC值)。
计算方法如下：
混剂实测毒力指数(ATI)＝标准药剂LC50值/混合药剂LC50值×100
混合药剂理论毒力指数(TTI)＝A药剂毒力指数×混剂中A的百分含量+B药剂毒力指数×混剂中B的百分含量
共毒系数(CTC)＝混剂实测毒力指数(ATI)/混剂理论毒力指数(TTI)×100
评价标准：若混剂共毒系数(CTC)≥120，表现为增效作用；80<CTC<120，为相加作用；共毒系数≤80，为拮抗作用。
实验结果：
(1)d-柠檬烯和胺鲜酯对香蕉黄胸蓟马的毒力测定
结果表明，d-柠檬烯、胺鲜酯对香蕉黄胸蓟马的LC 50值分别为36.16mg/L、47.06mg/L，说明d-柠檬烯对香蕉黄胸蓟马的毒力要高于胺鲜酯。见表1。
表1 d-柠檬烯与胺鲜酯对香蕉黄胸蓟马的毒力测定
Figure PCTCN2021115334-appb-000001
(2)混剂最佳配比筛选
采用按比例混合法进行混剂配比筛选，见表2，当混配比例为3：2和2：3时(有效成分近似配比为1：2和1：4)共毒系数分别为153和136，说明上述两种比例为明显的增效作用；而其它两种比例混配时的共毒系数分别为81和97，说明为相加作用。

Figure PCTCN2021115334-appb-000002
(3)混剂增效作用测定
以d-柠檬烯和胺鲜酯的有效成分比分别为2:1、3:2、1:1、2:3、1:2、1:2.5进行毒力测定，结果见表3。结果显示，所有供试复配剂对香蕉黄胸蓟马的共毒系数(CTC)均大于80，不表现出拮抗作用。其中，混配比例为1：1时增效作用最强，此时的共毒系数为179；当混配比例为3：2、2：3和1：2时，也表现出较强的增效作用，此时的共毒系数分别为125、153和140。

2、本发明所述农药组合物对香蕉蓟马的药效试验
靶标害虫：香蕉蓟马；
试验药剂：实施例1、2、7、8防治香蕉蓟马农药组合物水乳剂，实施例3、4、9、10防治香蕉蓟马农药组合物水悬浮剂，实施例5、6、11、12防治香蕉蓟马农药组合物油悬浮剂。
试验参照农药田间药效试验准则(二)(农业部农药检定所，2004)中关于钻蛀性害虫的农药田间药效试验方法进行。试验设计在海南省澄迈县福山镇文斗村红山二队，试验小区随机区组排列，每处理重复4次，每小区香蕉3株。
基数调查：施药前调查香蕉蓟马黑斑数并进行编号、挂牌；
施药方法：在选定的试验区域内，随机挑选同期现蕾的香蕉为试验对象，施药方式选择花蕾注射法和页面喷雾法。其中花蕾注射法通过花蕾注射器将药液通过喷杆注射入香蕉花蕾内部，全程只施1次；页面喷雾以传统喷雾为主，在香蕉现蕾时喷施1次，之后每间隔4d施药1次，共施药4次。要求喷雾均匀，以喷清水为对照。
药效调查与统计：第一次喷药后28d调查蕉果的蓟马点，以如下公式计算防效。施药后3d均无降雨天气。
防治效果％＝(对照组的黑斑数-处理组的黑斑数)/对照组的黑斑数×100％
试验结果
结果显示，d-柠檬烯与胺鲜酯复配制剂对香蕉黄胸蓟马的防治效果明显优于单剂单独使用，并通过施药方法发现花蕾注射法的防治效果明显优于传统喷雾法。由试验验结果可见，d-柠檬烯与胺鲜酯复配对香蕉蓟马具有较高的防治效果。见表4。

以实施例1～12的防治香蕉蓟马农药组合物作为制剂的质量指标的测定，按照《农药pH值的测定方法》(GB/T 1601)测定制剂的pH值，按照《农药持久起泡性测定方法》(GB/T 28137-2011)测定制剂的持久起泡性，按照《农药倾倒性测定方法》(GB/T 31737-2015)测定制剂的倾倒性，按照《农药热贮稳定性测定方法》(GB/T19136—2003)测定值制剂的热贮稳定性、《农药低温稳定性测定方法》(GB/T 19137—2003)测定值制剂的低温稳定性、《农药乳液稳定性测定方法》(GB/T1603—2001)测定值制剂的乳液稳定性，并观察外观，均为合格。
