The scientific name of rogor is O,O-dimethyl-S-(N-methylcarbamoylmethyl)phosphorodithioate. ① Dimethoate is a pesticide that is suitable for controlling sucking mouthpart pests on a variety of crops, such as aphids, leafhoppers, white flies, hidden leaf insects and some scale insects. It has good control effect and also has certain control effect on mites. In addition to being used as an inhalant, it is also a strong contact killer. It has a wide insecticidal spectrum and can be used to prevent and control the stinging and chewing mouths of various pests and spider mites such as vegetables, fruit trees, tea, mulberry trees, cotton, oil crops, grain crops, etc. Generally, 30 ~ 40g of active ingredients are used per acre. It is more effective against aphids. 15~20g of active ingredients can be used per acre. It has special effects on leafhopper flies on vegetables, beans, etc., with a special effect period of about 10 days.
②The main dosage form is 40% emulsifiable concentrate and ultra-low oil-soluble powder. It has low toxicity and can be rapidly degraded by glutathione transferase and carboxamidase into non-toxic normethoate and dimethoate in cattle, and can be used to prevent and control internal and external parasites in livestock. Dimethoate can be rapidly oxidized to dimethoate in plants and insects, increasing its toxic effects. The omethoate produced in the factory is called omethoate (40 EC), and the control objects and scope of application are the same as omethoate. However, due to its high toxicity, it is also effective at low temperatures, and the dosage can be about 1/3 less than dimethoate. For cotton aphids resistant to dimethoate, direct control of dimethoate still has good control effects, especially for cotton aphids on peppers, pomegranates and hibiscus in early spring, which have better overwintering effects.
① Dimethoate is an efficient broad-spectrum insecticide and acaricide with contact and systemic properties. It is highly toxic to various pests, especially those with mouthparts. Some fruit trees cannot play dimethoate, such as figs, dates, peaches, plums, apricots, olives, citrus and other fruit trees that cannot play dimethoate. If they are to be used, they must be tested for drug impairment before use. It mainly controls fruit flies, sawflies, planthoppers, leafhoppers, aphids, spider mites, miners, thrips, scale insects, etc. It is necessary to understand carefully to avoid unnecessary economic losses caused by this.
