1. 百菌清是属于什么类型的农药
百菌清属于低毒杀菌剂。
百菌清是广谱、保护性杀菌剂。作用机理是能与真菌细胞中的三磷酸甘油醛脱氢酶发生作用，与该酶中含有半胱氨酸的蛋白质相结合，从而破坏该酶活性，使真菌细胞的新陈代谢受破坏而失去生命力。百菌清没有内吸传导作用，但喷到植物体上之后，能在体表上有良好的黏着性，不易被雨水冲刷掉，因此药效期较长。
2. 农药“甲基托布津”和“甲托”是一种药吗，多菌灵和百菌清的作用有什么区别？
一、“甲基托布津”和“甲托”是同一种药。是一种广谱性内吸低毒杀菌剂，具有内吸、预防和治疗作用。 二、多菌灵和百菌清的主要区别 （一）、药剂特性不同 （1）、多菌灵 为白色结晶固体，熔点302℃～307℃（分解），密度1. 45glcm3 (20℃)。24℃时溶解度：水29mglL(PH4)，二甲基甲酰胺5g/L，微溶于其余有机溶剂中。低于50℃至少2年稳定。在碱性溶液中缓慢分解，随pH升高分解加快，随pH降低失去活性，以7作为基准。在酸中稳定形成可溶性盐。 （2）、百菌清 为白色晶体，熔点250-251℃，沸点350℃。蒸气压小于1.3Pa（40℃）。在水中溶解度为0.6ppm，在丙酮中为2g/kg，二甲苯中为8g/kg。工业品含量约为98%， 在碱和酸性水溶液中以及对紫外光照射，都是稳定的。制剂 2.5%，5%颗粒剂，75%可湿性粉剂。 （二）、作用机理不同 （1）、多菌灵 干扰病原菌有丝分裂中纺锤体的形成，影响细胞分裂，起到杀菌作用。 （2）、百菌清 能与真菌细胞中的三磷酸甘油醛脱氢酶发生作用，与该酶中含有半胱氨酸的蛋白质相结合，从而破坏该酶活性，使真菌细胞的新陈代谢受破坏而失去生命力。 （三）、应用不同 （1）、多菌灵 用于防治瓜类白粉病、疫病，西红柿早疫病，豆类炭疽病、疫病，油菜菌核病。还可以防治大葱、韭菜灰霉病，防治茄子、黄瓜菌核病，瓜类、菜豆炭疽病、豌豆白粉病，防治十字花科蔬菜、西红柿、莴苣、菜豆菌核病，西红柿、黄瓜、菜豆灰霉病等。 （2）、百菌清 可用于麦类、水稻、蔬菜、果树、花生、茶叶等作物。如麦类赤霉病，蔬菜病害（番茄早疫病、晚疫病、叶霉病、斑枯病、瓜类霜霉病、炭疽病）。此外还可用于桃腐病、疮痂病，茶炭疽病、茶饼病、网饼病，花生叶斑病，橡胶溃疡病，甘蓝霜霉病、黑斑病，葡萄炭疽病，马铃薯晚疫病，茄子灰霉病，橘子疮痂病等。 参考资料来源：百度百科-甲基托布津 参考资料来源：百度百科-多菌灵 参考资料来源：百度百科-百菌清
3. 1.三唑酮可与哪些农药互陪? 2.三唑酮是铜制剂吗？
三唑酮可与大多数农药互配，碱性农药除外。三唑酮不是铜制剂，此酮非彼铜。
4. 农药百菌清打多了怎么办
百菌清是杀菌剂，用量多了一般不会出现你说的这个情况；看你说的怀疑是使用了打过除草剂的药械，这个情况只好在后面加强管理了。
5. 1，3-二溴5,5-二甲基海因（简称：二溴海因）的MSDS哪里有啊？
呵呵，直接帮你贴过来

6. 老婆接触过农药三唑酮第二天身体肿痛是不是中毒了？
三唑酮是低毒杀菌剂，中毒症状：一般只对眼睛和皮肤有刺激性。应该没什么的，目前也没有特效解毒剂，只能由医生对症治疗。
7. 农业问题,百菌清与多菌灵都是杀菌的农药，不同之处有一个是外杀另一个是内杀，请问这两种药哪个杀菌效果更
百菌清为广谱保护性杀菌剂，化学性质稳定，无腐蚀作用，对人畜低毒，对鱼类毒性大，主要防治多种真菌性病害，但对土传腐霉属菌所引起的病害效果不好，对多菌灵产生抗药性的病害，改用百菌清防治能收到良好的效果。多菌灵为内吸性杀菌剂，对热稳定，对酸、碱不稳定，兼有保护和治疗作用，内吸传导主要是向顶型，对人、畜、鱼、蜜蜂低毒，在土壤中易分解失效。所为内吸剂，就是该药剂能被作物吸收到体内而不失效，能对植物体内的病原菌发生作用，这种药剂也称化学治疗剂，一般用于发病的植物，但大多数内吸剂也兼有触杀的作用。多菌灵就属此类。所为触杀剂，就是杀菌剂沉积在植物表面上与病原菌发生接触时杀灭或抑制病菌，这种药剂或者不能被植物吸收或者被植物吸收后立即分解失效，对植物体内的病菌不发生作用。百菌清就属此类。
百菌清是一种非内吸性广谱杀菌剂，对多种作物真菌病害具有预防作用。能与真菌细胞中的3-磷酸甘油醛脱氢酶发生作用，与该酶体中含有板胱氨酸的蛋白质结合，破坏酶的活力，使真菌细胞的代谢受到破坏而丧失生命力。百菌清的主要作用是防止植物受到真菌的侵害。在植物已受到病菌侵害，病菌进入植物体内后，杀菌作用很小。百菌清没有内吸传导作用，不会从喷药部位及植物的根系被吸收。百菌清在植物表面有良好的黏着性，不易受雨水等冲刷，因此具有较长的药效期，在常规用量下，一般药效期约7～10天。
8. 使用完百菌清后,植物叶面上留下百菌清的白色粉状物，怎么处理啊？
使用完百菌清后,植物叶面上留下百菌清的白色粉状物，如果是观叶植物，可以用柔软的湿棉布把比较明显的地方擦掉；如果是观花植物，可以不用处理。 因为百菌清在植物表面有良好的黏着性，不易受雨水等冲刷，因此具有较长的药效期，如果过早的把残留的粉状物处理掉，就失去了杀菌的效果。 百菌清化学结构： 扩展资料： 百菌清属于低毒杀菌剂。纯品为白色无味粉末，沸点350℃，熔点250-251℃，微溶于水，溶于二甲苯和丙酮等有机溶剂。 原粉含有效成份96%，外观为浅黄色粉末，稍有刺激臭味，对酸、碱、紫外线稳定。低毒，对兔眼睛和角膜有明显刺激作用，可产生角膜混浊，且不可逆转，但对人眼睛没有此种作用。对少数人皮肤有刺激作用。 对鱼毒性大。原粉大鼠急性经口和兔急性经皮LD50均大于10000毫克/公斤，大鼠急性吸入LD50>4.7毫克/升(1h)。对兔眼有强烈刺激作用，对某些人眼有明显的刺激作用。在试验条件下无致畸、致突变作用，对鱼毒性大。
