Are there any colleagues who work with dimethomorph? Let’s exchange experiences.
Reply #22019-12-26
Taken from the Internet. Fungicides, primarily used to control diseases such as downy mildew and late blight on fruit trees like grapes. Basic information: Other Chinese names include dimethomorph, Shuang’an, Anke, Zhuanke, Xiongke, Anma, Lüjie, Pojun, Gualong, Shangpin, Lingpin, Shiyun, Liangshuang, Shuangsuang, Shuangdian, Xueyi, Douyi, Bacui, Juwang, Yourun, Qiayifa, and Yiguaxiang. Chemical name: (E,Z)-4-Morpholinemethanol. Toxicity: It is a low-toxicity fungicide. The acute oral LD50 in rats is >3900 mg/kg, the acute dermal LD50 is >2000 mg/kg, and the acute inhalation LC50 in rats is >4.24 mg/L. It is non-irritating to rabbit skin, but causes mild irritation to the eyes. Under experimental conditions, there were no mutagenic, teratogenic, or carcinogenic effects; in a 90-day feeding study in rats, the no-effect dose was 200 mg/kg. Moderately toxic to fish; the LC50 for carp is 14 mg/L (96 hours). Under normal use conditions, it is low in toxicity to bees, with an oral LD50 > 100 micrograms per bee. It has no toxic effect on silkworms and is low in toxicity to birds; the acute oral LD50 for wild ducks is >2000 mg/kg. It has no effect on natural predators; the dose that has no effect on earthworms is 1000 mg/kg of soil. The main formulations are 50% dimethomorph wettable powder, 69% dimethomorph-manganese zinc wettable powder, 55% dimethomorph-fop wettable powder, and 50% water-dispersible granules. Its characteristic is that it is a fungicide specific to Oomycetes; it works by disrupting the formation of the cell wall membrane, and it is effective at all stages of the oomycete life cycle, being particularly sensitive during the formation of sporangia and oospores, even at very low concentrations

What should be discussed? We need a set of rules – how can discussions take place with such vague titles? There are many people on this forum who work in engineering, design, and production technology; those involved in organic technology may be fewer. The possibility of niche similar products is lower. Production technology issues need to be transformed into standard technologies in order to facilitate communication; market information is understood by peers, but they may not be willing to share it

Enalmofoze is synthesized from N-acetylmorpholine produced by Dohwa; a small amount of the product remains in the mother liquor after centrifugation, and there is currently no method for recovering it. I would like to ask everyone for advice
