* * * * * * * * * * * * * * * * Residues deposited on the stems can move across epidermial cells and into the vessel elements of the xylem, allowing for translocation into untreated foliage through the xylem stream. * * * * * * * * * * * * * * 各剂型均仅需基本的个人防护装备 基于活性成分Rynaxypyr?的毒性特点，各剂型均仅需基本的个人防护装备： 对20％ SC和35％ WG，美国所提议的个人防护装备如下： 长袖衬衣 长裤 鞋子和袜子 药后再入园间隔期短 首批登记内容 * 国内的登记作物，防治对象和施药技术 产品 第一批登记对象 用药方法 50 SC 27-40gai/ha： 甘蓝小菜蛾和甜菜夜蛾花椰菜/小菜蛾和甜菜夜蛾 施用时期：卵孵高峰期用药；若发生严重，可于7天后，重复喷药一次，推荐采收间隔期1天 使用方法：兑水，稀释至1000倍，茎叶均匀喷雾，亩用水量45公斤 35% WG 苹果树/金纹细蛾：17500倍 苹果树/桃小食心虫：8750倍 施用时期：蛾量急剧上升时，即刻使用本产品。提前1－2天使用，效果更好。连续用药时，推荐采收间隔期为14天。 使用方法：茎叶均匀喷雾，保证足够喷液量（常规亩用水量200公斤） 200 SC 30gai/ha 水稻/二化螟和稻纵卷叶螟 施用时期：对稻纵卷叶螟，卵孵高峰期用药；若发生严重，可于14天后，重复喷药一次。推荐采收间隔期7天。 对二化螟，卵孵高峰期至水稻枯鞘株率达1－3％时用药。 使用方法：兑水茎叶均匀喷雾，亩用水量30公斤。 * * Following ingestion of Rynaxypyr? , there is a rapid effect on skeletal and cardiac muscle. Typical symptoms of insect intoxication include rapid feeding cessation, general lethargy, regurgitation, and muscle paralysis Severe stunting is observed (as depicted in this picture where intoxicated larvae are compared to untreated larvae) Because the onset of feeding cessation occurs within minutes of exposure, protection of the crop is essentially immediate. Death itself occurs within 72 hours (depending on rate, instar, species sensitivity, environmental conditions, etc.) * Rynaxypyr? has a novel mode of action which means that it DOES NOT interact with any of the biochemical targets affected by other commercialized insecticides. Shown in this slide is the neuromuscular signaling pathway of insects. Nerve conduction involves the activation of sodium channels (targeted by indoxacarb and pyrethroids) and release of the neurotransmitter, acetylcholine (targeted by organophosphate and carbamate insecticides). Receptors for the acetylcholine neurotransmitter are the target site of neonicotinoid and naturalyte insecticides. The cyclodienes and fipronil inhibit function of another neurotransmitter
