Effects and uses of phoxim

Phoxim is an organophosphorus insecticide that has a strong contact killing effect on pests, a fast killing speed and a long lasting effect. So what are the specific functions and uses of Qi? Let’s learn more about it below.

Effects and uses of phoxim

Phoxim has excellent contact killing effect, is also a stomach poison, has no systemic effect, and is very effective against Lepidoptera larvae. In the field, it is unstable to light and decomposes quickly, so the residual period is short and the residual risk is small. However, if the drug is applied to the soil, the residual period is very long, making it suitable for controlling underground pests . Its main mechanism of action is to inhibit the activity of cholinesterase in insects. When pests come into contact with the drug solution, their nervous system becomes paralyzed and poisoned, causing them to stop eating and die.

How to use phoxim

1. Targets of prevention and treatment

It mainly prevents and controls underground pests and Lepidoptera larvae, such as white grubs , cutworms, corn borers, etc. It can also prevent and control sanitary pests such as mosquitoes and flies and storage pests.

2. Usage and Dosage

(1) Prevention and control of peach borer and other borer species: When the overwintering larvae of peach borer emerge from the soil, use 500 g of 50% phoxim emulsifiable concentrate or 500-600 g of 25% phoxim microcapsule aqueous suspension per 667 m2, add 150 kg of water, and spray on the orchard floor, with a focus on spraying around the tree pits.

(2) Control of moth pests such as leaf rollers, leaf miners and caterpillars: In the early stage of pest infestation, spray 1000-1500 times diluted 50% phoxim emulsifiable concentrate for control.

3. Usage

(1) Cucumbers, beans, sorghum and sugar beets are sensitive to phoxim and are easily harmed by it.

(2) Phoxim is easily decomposed by light, so be sure to cover the area with soil in time when using it.

(3) Phoxim has no systemic properties and requires full and uniform spraying. Cannot be mixed with alkaline substances.

(4) When spraying in the field, it is best to do it in the evening or on cloudy days. The mixed and steamed seeds should also be dried away from light and stored in a dark place.

In general, phoxim is a low-toxic organophosphorus insecticide that is mainly contact and stomach poisonous and has no systemic effect. It has a broad insecticidal spectrum and wide applicability.
