Omethoate is a highly toxic pesticide with strong systemic, contact and certain stomach toxicity. Many farmers often use omethoate to control aphids. In addition, it can also be used to control scale insects and vegetable aphids. Various insect pests such as rice planthoppers, in order to master the correct method of using omethoate, Xiaobian summarized the dosage standards for different pests and omethoate.

1. Control red spider, rust tick, hibiscus, scale insect, pear cockroach, chafer, etc., spray with 40% emulsifiable concentrate 1000 times.

2, used to control cotton aphid, cotton scorpion horse, red spider, leaf scorpion, etc., can use 40% emulsifiable oil 50 ml per acre, 50-75 kg spray with water.

3, prevention and control of red peony pepper flea, when the germination of the pepper, the overwintering adults on the tree activity and the flower buds grow to about 1.5 cm, spray 40% with 40% emulsifiable oil 1000-1500 times.

4, used to control vegetables, vegetables, scorpion horses, leaf miner and other pests, can use 40% emulsifiable oil 50 ml per acre, 60-80 kg spray with water.

Grinding Glass Microsphere
1. To select glass beads in types, sizes and quantity in accordance with viscosity, rigidity and dispersal of the grinded materials. 
2. To clean glass beads and mill's inside before the grinding processed. 
3. To input the grinded materials firstly and a curtain amount of glass beads later. To add continuously glass beads till 70%~80% of the mill is full. 
4. To forbid to keep glass beads funning with little grinded material for a long time, as the glass beads inside the mill are easily broken at high speed operation. 

5. To add new glass beads to ensure the quality and efficiency of grinded materials. 

Grinding Glass Beads are mainly used for the disperser, grinding media of industries, such as coloring, paint, ink, coatings, resins, chemical engineering, with the advantages of smooth surface, even size, high hardness, good chemical stability. Thanks to the characteristics of heat-resistant, wearable, compression strength, the filling-type bead could be used to improve glass fibre reinforced plastic, rubber, and so on.
The glass bead can be produced based on the standard of countries or areas, such as EN1423/1424, AASHTO M247, BS6088, JIS R3301 and KS L2521 etc.
