Krishikranti Loki Fenvalerate 20% EC | Synthetic Pyrethroid Insecticide for Bollworm, Shoot & Fruit Borer, Aphid, Jassid, Thrips & Diamond Back Moth Control in Cotton, Brinjal, Okra, Chilli & Cauliflower

What is Fenvalerate 20% EC? Fenvalerate 20% EC is a broad-spectrum synthetic pyrethroid insecticide with contact and stomach action for fast knockdown of chewing, sucking, and boring pests. Krishikranti Loki Fenvalerate 20% EC is the cost-effective solution for bollworm, shoot and fruit borer, diamond back moth, aphids, jassids, and thrips in cotton, brinjal, okra, chilli, and cauliflower. It gives instant knockdown within minutes of contact and continues protecting the crop for 10–15 days. Non-systemic stays on the plant surface where pests feed, giving reliable contact kill. How Fenvalerate 20% EC Works Action Type How It Works Contact Action Kills pests on direct contact instant knockdown within minutes of spray Stomach Action Pests die after eating treated leaves disrupts sodium channels causing paralysis and death Photostable Does not break down in sunlight works longer than older pyrethroids (10–15 days residual) Repellent Effect Deters new pests from landing on treated crop prevents re-infestation Why fenvalerate works when others fail: Many pests have developed resistance to organophosphate and carbamate insecticides. Fenvalerate belongs to a different chemical group (pyrethroid) and gives effective control even against resistant pest strains. Quick kill + long residual = fewer sprays needed.

Benefits of Fenvalerate 20% EC Instant knockdown : kills pests within minutes of contact spray Broad spectrum : controls chewing, sucking, and boring pests in one spray Photostable pyrethroid : does not degrade in sunlight, works for 10–15 days Contact + stomach action : kills on direct contact and through ingestion Repellent effect : deters new pests from landing on treated crop Effective against resistant strains : works even when organophosphate and carbamate insecticides fail Multi-crop use : cotton, brinjal, okra, cauliflower, chilli, tomato, potato, grapes Low dose, high efficacy : only 2.5–3 ml per litre, 500 ml per acre Cost-effective : fewer sprays needed due to long residual activity Frequently Asked Questions Q1: What is fenvalerate 20% EC used for? Fenvalerate 20% EC is a synthetic pyrethroid insecticide used to control bollworm, shoot and fruit borer, diamond back moth, aphids, jassids, thrips, and caterpillar pests in cotton, brinjal, okra, cauliflower, chilli, tomato, and other crops through contact and stomach action. Q2: What is the dosage of fenvalerate 20% EC per litre and per acre? Use 2.5 to 3 ml per litre of water for foliar spray. Per 15 litre pump: 40 to 50 ml. Per acre: 500 ml in 200 litres of water. One spray gives 10 to 15 days protection. Q3: How fast does fenvalerate insecticide kill pests? Fenvalerate gives instant knockdown pests die within minutes of contact. It disrupts the sodium channels in the pest nervous system causing immediate paralysis and death. The photostable formula continues killing new pests for 10 to 15 days after spray. Q4: Is fenvalerate 20% EC effective for bollworm control in cotton? Yes. Fenvalerate 20% EC is one of the most effective and affordable contact insecticides for American bollworm and spotted bollworm in cotton. Apply 500 ml per acre at first sign of bollworm eggs or small larvae. Works on larvae that have developed resistance to older organophosphate sprays. Q5: Is fenvalerate effective for shoot and fruit borer in brinjal? Yes. Fenvalerate 20% EC gives excellent control of brinjal shoot and fruit borer. Spray 2.5 to 3 ml per litre when first bore holes appear on shoots or fruits. Repeat every 10 to 15 days during peak fruiting season. Contact action kills borers before they enter the fruit. Q6: What is the difference between fenvalerate and cypermethrin? Both are synthetic pyrethroids with contact and stomach action. Fenvalerate is more photostable and gives longer residual activity (10 to 15 days vs 7 to 10 days for cypermethrin). Fenvalerate also has stronger repellent effect against pests. Cypermethrin has slightly faster initial knockdown. Both work against similar pests. Q7: What is the pre-harvest interval for fenvalerate 20% EC? PHI is 7 to 14 days depending on the crop. For vegetables like brinjal, okra, and cauliflower maintain a minimum 7 days gap between last spray and harvest. For cotton there is no PHI concern as the fibre is not consumed as food. Q8: Can fenvalerate 20% EC be mixed with other insecticides? Yes. Fenvalerate can be tank-mixed with most organophosphate insecticides like chlorpyriphos, profenofos, and acephate for enhanced broad-spectrum control. Do not mix with alkaline pesticides or Bordeaux mixture. Always do a jar test before tank-mixing new combinations.
