ПРОПАНИЛ химические свойства, назначение, производство
Описание
propanil is used
as a rice herbicide. The resistance of rice plants toward
propanil has been found in an enzyme aryl-acylamidase
that rapidly hydrolyzes the herbicide. This enzyme can be
inhibited by carbamate insecticides, and this can lead to
an increased propanil phytotoxicity (38).
Химические свойства
Propanil is a colorless solid. The technical
product is a brown crystalline solid.
Использование
Propanil is a a widely used herbicide. Propanil is used mainly to control weed growth in rice fields.
Общее описание
Colorless to brown crystals. Non corrosive. Used as an herbicide.
Реакции воздуха и воды
Hydrolyzed by acid and alkaline media.
Профиль реактивности
Propanil is incompatible with carbamates and organophosphates.
Опасность
Toxic by ingestion and inhalation.
Сельскохозяйственное использование
Herbicide: Propanil is a post-emergence herbicide with no residual effect. It is used against numerous grasses and broadleaved weeds in rice, potatoes, and wheat. Mixing with carbamates or organophosphorus compounds is not recommended. It is also used on wheat in a mixture with MCPA. With carbaryl, it is used in citrus crops grown in sod culture. Not approved for use in EU countries (re-submitted). Registered for use in the U.S.

Несовместимости
Incompatible with oxidizers (chlorates,
nitrates, peroxides, permanganates, perchlorates, chlorine,
bromine, fluorine, etc.); contact may cause fires or explo-
sions. Keep away from alkaline materials, strong bases,
strong acids, oxoacids, epoxides.
Утилизация отходов
Hydrolysis in acidic or basic
media yields the more toxic substance, 3,4-dichloraniline,
and is not recommended.
