Deltamethrin 11% w/w EC (DELTA PLUS) is a highly effective synthetic pyrethroid insecticide by Harishree Crop Science with strong contact and stomach action for controlling bollworms, fruit borers, stem borers, leaf-eating caterpillars, thrips, aphids, and various chewing and sucking pests on cotton, chilli, tomato, brinjal, okra, paddy, pulses, oilseed crops, and vegetables. Recommended dose: 10 ml per pump.
Synthetic pyrethroid mode of action — Deltamethrin disrupts sodium channels for contact and stomach pest control.
On application, DELTA PLUS forms an even emulsifiable concentrate film on leaf surfaces. Chewing and sucking pests ingest or contact treated foliage during feeding, absorbing Deltamethrin through cuticle and gut.
Deltamethrin acts on contact, disrupting sodium channels in insect nerve tissue. Pests exposed to the spray deposit experience rapid paralysis and immediate cessation of feeding damage.
When caterpillars, borers, and bollworms ingest treated plant tissue, Deltamethrin delivers strong stomach poison insecticide activity — effective control of hidden feeders on leaf undersides.
As a Type-II synthetic pyrethroid, Deltamethrin prolongs sodium channel opening in nerve axons, causing uncontrolled nerve firing, knockdown, and death of target pests.
The EC formulation adheres to foliage and maintains contact insecticide activity on treated surfaces, protecting crops from pest resurgence between scheduled spray intervals.
Rotate DELTA PLUS with IGRs, organophosphates, and other MOA groups across the season to reduce selection pressure on bollworm, caterpillar, thrips, and aphid populations.
