Description
技术领域
本发明属于农药复配领域,涉及一种杀虫组合物及其应用,尤其是一种以磷腈氟烷基磺酰亚胺碱金属盐和丁醚脲为主要活性成分的杀虫组合物及其应用。
背景技术
施用化学药剂是防治植物真菌病害的最为有效的手段。但长期连续高剂量地施用单一的化学杀虫剂,容易造成药剂的残留、环境污染以及耐抗药性真菌发展等问题。合理的化学杀虫剂复配或混配具有扩大杀虫谱,提高防治效果、延长施药适期、减少用药量、降低药害、减少残留、延缓真菌耐药性和抗药性的发生与发展等积极特点,杀虫剂复配或混配是解决上述问题的最为有效的方法之一。开发新品杀虫剂价格不断攀升,而相比之下,开发与研究高效、低毒、低残留的复配与混配具有投资少,研制周期短而受到国内外重视,纷纷加大开发研制力度。
丁醚脲(monosultap):2-N,N-二甲胺基-1-硫代硫酸钠基-3-硫代硫酸基丙烷
纯品为针状结晶,熔点142~143℃,工业品为无定形颗粒状固体或白色、淡黄色粉末,有吸湿性,易溶于水,20℃时水中溶解度1.335g/mL,易溶于工业酒精及热无水乙醇中,微溶于甲醇,二甲基甲酰胺、二甲基亚砜,不溶于丙酮,乙醚、氯仿、醋酸乙酯、苯等溶剂,常温下稳定,pH5-9条件下稳定,遇铁降解,在强碱,强酸条件下易分解。是一种人工合成的沙蚕毒素的类似物,进入昆虫体内迅速转化为沙蚕素或二氢沙蚕毒素。该药为乙酰胆碱竞争性抑制剂,具有较强的触杀、胃毒和内吸传导作用,对鳞翅目害虫的幼虫有较好的防治作用,该药主要用于防治甘蔗、水稻等作物上的害虫。对家蚕有毒,使用时应特别注意。对棉花、烟草和某些豆类易产生药害,马铃薯也较敏感。[3]不能与强酸、强碱物质混用。

具体实施方式
丁醚脲与磷腈氟烷基磺酰亚胺碱金属盐不同配比联合毒力,通过以下实施例进一步对本发明进行解释,但不能限制本发明的范围。
1.1供试药剂
91%丁醚脲原药、97%磷腈氟烷基磺酰亚胺碱金属盐。
1.2供试虫源
东莞瑞德丰科技公司生测部室内连续饲养5代且其个体大小和生理状态一致的敏感型小菜蛾的三龄幼虫。
1.3两个单剂室内毒力测定
采用浸虫法将两个原药都用少量丙酮溶解,再用0.1%的吐温水溶液稀释成成等差的5个浓度的溶液,稀释在烧杯里以备用,并以清水作为对照。将大小一致的三龄小菜蛾幼虫在浸虫笼的药液中浸渍5S,吸去多余药液后将其置于直径为9cm的培养皿中,皿中放有新鲜甘蓝叶片加盖。每浓度处理10头,重复4次。设空白对照。于(27±1)℃光照培养箱中保持24h后检查死亡率,用拨针轻触虫体无反应者为死亡。死亡率用Abbott公式校正,再根据浓度对数——死亡率机率值分析(Bliss)法,求出毒力回归方程和置死中量LC50的值。
2.1最佳配比筛选
按比例混合(Crafte)法进行混配寻优,筛选出丁醚脲与磷腈氟烷基磺酰亚胺碱金属盐混配的最佳配比。设丁醚脲和磷腈氟烷基磺酰亚胺碱金属盐对小菜蛾的三龄幼虫24小时的室内毒力LC50分别为a和b,两药剂混配时按下列比例混配成11个配方,即为a+0、0.9a+0.1b、0.8a+0.2b、0.7a+0.3b、0.6a+0.4b、0.5a+0.5b、0.4a+0.6b、0.3a+0.7b、0.2a+0.8b、0.1a+0.9b、0+b。每个配比的药液按上述方法进行毒力测定,24小时后检查小菜蛾的死亡结果,求出各配比的毒性比率表1。
表1LC50剂量的丁醚脲与LC50剂量的磷腈氟烷基磺酰亚胺碱金属盐不同配比对小菜蛾的室内毒力测定结果
根据表1结果,以两个单剂的LC50为基础,组成不同配比对小菜蛾的毒力测定,从表初步可以看出,不同配比的混剂均有增效作用,它们的实际抑制率均大于或接近50%,毒性比率均大于1。其中以0.6a+0.4b的混剂实际死亡率最高。因此,混剂的最佳配比为丁醚脲LC50值的60%加磷腈氟烷基磺酰亚胺碱金属盐LC50值的40%,折算成两单剂有效成分的比例则为2.325∶1。参照最佳配比结果,实际以丁醚脲∶磷腈氟烷基磺酰亚胺碱金属盐=2.325∶1(有效成分)进行混配,混配制剂用丙酮稀释成一定梯度的系列浓度,再进行室内毒力测定,混剂测定的毒力回归方程、LC50以及共毒系数并按孙云沛方法计算共毒系数(CTC)。共毒系数CTC,计算公式如下:(以丁醚脲为标准药剂,其毒力指数为100):
磷腈氟烷基磺酰亚胺碱金属盐的毒力指数(TI)=丁醚脲的LC50/磷腈氟烷基磺酰亚胺碱金属盐的LC50×100
M的实际毒力指数(ATI)=丁醚脲的LC50/M的LC50×100
M的理论毒力指数(TTI)=丁醚脲的TI×P丁醚脲+磷腈氟烷基磺酰亚胺碱金属盐的TI×P磷腈氟烷基磺酰亚胺碱金属盐
M的共毒系数(CTC)=M的ATI/M的TTI×100
式中:
M为磷腈氟烷基磺酰亚胺碱金属盐与丁醚脲不同配比的混合物
P磷腈氟烷基磺酰亚胺碱金属盐为磷腈氟烷基磺酰亚胺碱金属盐在混剂中所占的比例
P丁醚脲为丁醚脲在混剂中所占的比例见表2。
表2丁醚脲、磷腈氟烷基磺酰亚胺碱金属盐及其混剂对小菜蛾的室内毒力测定结果
表2表明,实际以丁醚脲∶磷腈氟烷基磺酰亚胺碱金属盐=2.325∶1(有效成分)进行混配,再进行室内毒力测定,共毒系数为175.67,其增效作用明显。
3.1田间实验防治小菜蛾,.二化螟
3.1田间实验防治小菜蛾
3.1试验方法
3.1.1施药方法
该试验喷药1次,施药日期为3月20日。此时甘蓝尚未结球。小菜蛾幼虫大部分处于2~3龄期。喷药时天气晴。用新加坡利农牌定压背负式手动喷雾器对各处理均匀喷雾,叶片正反面都要求喷有效药液。每小区用药液2.0kg。
3.1.2调查方法
调查每个小区固定10株甘蓝作为调查株.记录全部叶片上的幼虫数量。喷药前调查虫口基数,分别在喷药后3、7天和10天调查活虫数。本试验共调查4次。
3.1.3药效计算方法
虫口减退率(%)=(施药前活虫数一施药后活虫数)/施药前活虫数×l00
防效(%)=(处理区虫口减退率-对照区虫口减退率)/(100-对照区虫口减退率)×100
3.1.4药害调查方法
施药后连续10d目测药剂对作物没有药害产生,甘蓝生长良好。
3.1.5田间药效试验试验结果
表3处理药剂防治小菜蛾田间药效试验结果
从表3可以看出,不同比例的混配药剂,按不同的用量进行大田试验,药后其对甘蓝小菜蛾的防治效果均优于对照药剂,混剂45%(杀∶丁=2.325∶1)在药后10天,杀虫效果分别为88.61%、92.85%和95.93%,杀虫效果随着用量的增加而增大,各用量处理杀虫效果之间差异达到极显著。根据田间目测,在试验剂量范围内,作物生长正常,各处理药剂均未出现对甘蓝的药害现象,说明其对甘蓝是安全的。在试验过程中,试验人员发现其对蚜虫等害虫也有较好防效。建议与作用机理不同的杀虫剂混合使用以延缓害虫抗药性的产生。现在各蔬菜产区的小菜蛾有很高的抗药性,用常规药剂进行防治已防效甚微,控制不了其危害,这一混配中因有磷腈氟烷基磺酰亚胺碱金属盐的独特机理能很好的解决抗药性这一难题,在蔬菜产区有推广的价值。
