Description
技术领域
本发明属于农药技术领域，具体涉及有效成分为氯虫苯甲酰胺、噻虫嗪和嘧菌酯的组合物，用于水稻二化螟、稻飞虱、纹枯病常发性病虫害综合防治。
背景技术
水稻二化螟、稻飞虱、纹枯病是水稻为害性强、发生率高、防治次数多、发生面积广且同时发生的主要病虫害，一般农民从水稻播种到水稻收获需防治病虫害3～4次，尤其在水稻分蘖期、抽穗期是二化螟、稻飞虱和纹枯病综合防治主要时期，防治时常用多种药剂混合使用或多次重复施药才能达到防治目的。
不同农药品种的混配，是防治农业病虫害、扩大防治范围的常见方法。通过农药科学组合，筛选出合理的配方，可有效提高实际防治效果，扩大防治范围，减轻劳动强度，是病虫害综合治理的重要手段。
氯虫苯甲酰胺(chlorantraniliprole)，化学名称：3-溴-N-[4-氯-2-甲基-6-[(甲氨基甲酰基)苯]-1-(3-氯吡啶-2-基)-1-氢-吡啶-5-甲酰胺，属邻甲酰氨基苯甲酰胺类杀虫剂。主要是激活兰尼碱受体，释放平滑肌和横纹肌细胞内贮存的钙离子，引起肌肉调节衰弱，麻痹，直至最后害虫死亡。具有内吸传导作用，能通过根、茎吸收传导，对水稻二化螟等钻蛀性隐蔽害虫具有较好防治作用。
噻虫嗪(thiamethoxam)，化学名称：(RS)-1-甲基-2-硝基-3-(四氢-3-呋喃甲基)胍，属烟碱类杀虫剂。具有内吸传导作用，是通过脊柱神经传递和触杀胃毒作用的系统性杀虫剂，可以快速被植物吸收广泛散布，对烟碱乙酰胆碱受体有兴奋作用，对刺吸式口器害虫有突出防效。
嘧菌酯(azoxystrobin)，化学名称：(E)-2-{2-[6(2-氰基苯氧基)嘧啶-4-基氧]苯基}-3-甲氧基丙烯酸酯，线粒体呼吸抑制剂，即通过在细胞色素Bcl向细胞色素C的电子转移，从而抑制线粒体的呼吸。对14-脱甲基化酶抑制剂、苯甲酰胺类、二羧酰胺类和苯并咪唑类产生抗性的菌株有效。具有保护、铲除、渗透、内吸活性。抑制孢子萌发和菌丝生长并一直产孢。
本发明人对氯虫苯甲酰胺、噻虫嗪和嘧菌酯组合应用深入研究，发现氯虫苯甲酰胺、噻虫嗪和嘧菌酯进行混配制备成颗粒剂，一次性使用能达到水稻二化螟、稻飞虱和纹枯病常发性病虫害综合防治目的。经进一步研究，完成了本发明。
发明内容
本发明的目的在于提供一种水稻病虫害防治药剂，该农药可同时防治水稻二化螟、稻飞虱和纹枯病，扩大防治范围，降低劳动强度，节省农药加工及流动成本。
技术方案：一种水稻病虫害防治药剂，有效成分为氯虫苯甲酰胺、噻虫嗪和嘧菌酯，氯虫苯甲酰胺、噻虫嗪和嘧菌酯的质量份数比为1～20:1～20:1～40，氯虫苯甲酰胺、噻虫嗪和嘧菌酯质量总和在农药组合物中的质量百分比为0.1％～60％，其余为农药助剂。
本发明一种水稻病虫害防治药剂根据现有农药制备方法可制备成颗粒剂。
本发明一种水稻病虫害防治药剂的施药方式是撒施，使用频率和施用量随天气状况和水稻病虫害发生程度而变化，可以通过使用适当的次数或剂量达到防治的目的。
本发明适用于水稻二化螟、稻飞虱和纹枯病的综合防治。
与现有技术相比，本发明有如下显著效果。
本发明的优点在于：1、氯虫苯甲酰胺、噻虫嗪和嘧菌酯组合扩大防治范围，提高防治效果，达到水稻二化螟、稻飞虱和纹枯病常发性病虫害综合防治目的。2、氯虫苯甲酰胺、噻虫嗪和嘧菌酯组合，减少生产工艺、农药助剂用量、包装物、产品流通，降低成本。3、一次使用达到了多重效果，降低劳动强度，减少了农药对环境污染。
具体实施方式
为了更好地理解本发明的实质，下面结合实施例对本发明的内容作进一步详述，实施例中所提及的内容并非对本发明的限定，制备方法中温度、时间等工艺条件的选择可因地制宜而对结果并无实质性影响。
本发明的基本方案：一种水稻病虫害防治药剂，有效成分为氯虫苯甲酰胺、噻虫嗪和嘧菌酯，其余为农药助剂。氯虫苯甲酰胺、噻虫嗪和嘧菌酯的质量份数比为1～20:1～20:1～40，氯虫苯甲酰胺、噻虫嗪和嘧菌酯质量总和在农药组合物中的质量百分比为0.1％～60％。
实施例1：5％氯虫苯甲酰胺·噻虫嗪·嘧菌酯颗粒剂
按重量计有效成分氯虫苯甲酰胺0.5％，噻虫嗪0.5％，嘧菌酯4％，轻钙5％，尿素3％，木质素2％，聚乙烯醇0.5％，工业明胶2％，高岭土至100％。把上述材料投在密闭的调配釜中混合均匀，包膜法造粒，在110℃～120℃条件下干燥至颗粒含水量小于3％，筛分，粒度范围2000μm～4000μm，经检验合格后，即得到所需的颗粒剂；粉末筛分物经粉碎后返回至搅拌罐重新混合，不合格品经检验分析原因后返回至搅拌罐重新混合，混合采用分步法，组分含量较低的原材料先混合分散助剂或填料再与其它物料混合，以确保产品含量的均匀性，干燥温度在110℃～120℃，严格控制温度的变化及波动。
