Sumitomo Kemtrek Chlorpyrifos 20% EC Insecticide – Controls Bollworms, Stem Borer, Leaf Roller & Termites

Sumitomo Kemtrek is a broad-spectrum chemical insecticide containing Chlorpyrifos 20% EC (Emulsifiable Concentrate). It belongs to the organophosphate group and is widely trusted by Indian farmers for controlling chewing, sucking, and soil-dwelling pests across field and horticultural crops. Kemtrek works through contact, stomach, and vapour action, giving quick knockdown of pests along with long-lasting residual control.

This insecticide is effective against bollworms, stem borers, leaf rollers, leaf folders, termites, white grubs, cutworms, and root grubs. It is recommended on crops such as paddy, cotton, sugarcane, maize, groundnut, wheat, barley, brinjal, onion, cabbage, apple, ber, and citrus. In sugarcane, it is used as a soil treatment for termite control, while in other crops it is applied as a foliar spray. Kemtrek also supports strong crop establishment and plant vigour, helping protect yield potential by reducing pest damage.

Being a Yellow Label product, it requires careful handling with proper protective gear and strict adherence to label directions. It is a dependable, economical choice for farmers who need reliable control of both above-ground and soil-borne insect pests.

Key Benefits

• Controls a wide range of chewing, sucking, and soil pests including bollworms, stem borers, leaf rollers, termites, white grubs, and cutworms in one product.
• Works through contact, stomach, and vapour action, giving quick knockdown of pests and long-lasting residual protection.
• Effective as a foliar spray and as a soil treatment, especially for termite control in sugarcane.
• Helps improve crop establishment and plant vigour by protecting young plants from soil-borne pests.
• Reduces crop damage and helps protect yield potential across multiple field and horticultural crops.
• Economical and widely trusted insecticide suitable for small and large farms.

How It Works

Kemtrek contains Chlorpyrifos, an organophosphate insecticide that acts on the nervous system of insects. It works by inhibiting the acetylcholinesterase enzyme, which is essential for transmitting nerve impulses. When this enzyme is blocked, nerve signals are disrupted, causing paralysis and eventual death of the target pest.

Because it acts through contact, stomach, and vapour action, Kemtrek controls pests that come into direct contact with the spray, pests that feed on treated plant parts, and even some pests exposed to its vapour. This multi-mode action makes it effective against both foliar insects and soil-dwelling pests like termites and root grubs, providing dependable control in the field.

• Soil treatment: For termite control in sugarcane, apply as a soil treatment.

Always follow the exact dose and method given on the product label for your specific crop and pest situation.

When to Use

Kemtrek should be applied when pest infestation is first noticed or when pest population reaches the economic threshold level for the crop. Early application gives the best control and prevents pests from spreading to healthy plants.

• Apply as a foliar spray when bollworms, stem borers, leaf rollers, or leaf folders appear on the crop.
• For termite control in sugarcane, use soil treatment at planting or when termite activity is observed.
• For soil pests like white grubs, cutworms, and root grubs, apply at the time of crop establishment to protect young plants.
