✓ CIB&RC lists up to 30 September 2026
Find your problem (a pest, a disease or a weed) and see each chemical approved for it on cucumber, how much to use per acre and in one 15-litre pump, the last spray before harvest, and the brands that sell that exact chemical. From the government's CIB&RC lists; nothing here is paid for.
How to use this page
Figures are rounded; the label of the pack you buy is final. Wear gloves and a mask while spraying.
Brand names are given only to help you find the product. Before buying, check that the chemical name and strength printed on the pack match what is shown here. Names marked ⓘ are from trade listings and not yet confirmed by the company; spelling mistakes are possible. For clarity, contact your nearest agri-input store (कृषी सेवा केंद्र) or agriculture officer. Other brands with the same chemical and strength work the same way. NanoKheti does not sell or endorse any brand.
ब्रँडची नावे फक्त उत्पादन ओळखण्यास मदत व्हावी म्हणून दिली आहेत. खरेदी करण्यापूर्वी पाकिटावर छापलेले रसायनाचे नाव व प्रमाण येथे दिलेल्याशी जुळते का ते तपासा. ⓘ खूण असलेली नावे व्यापारी यादीतून घेतली आहेत व कंपनीकडून अजून पडताळलेली नाहीत; नावात चूक असू शकते. अधिक माहितीसाठी जवळच्या कृषी सेवा केंद्राशी किंवा कृषी अधिकाऱ्याशी संपर्क साधा. तेच रसायन व तेच प्रमाण असलेले इतर ब्रँडही तसेच काम करतात. नॅनोखेती कोणताही ब्रँड विकत नाही किंवा त्याची शिफारस करत नाही.

Dose: per acre = the list’s dose per hectare × 0.405; per pump = the dose for a 15-litre pump at the water the list gives; rounded. Where the list gives the dose as a strength of the spray, the pump amount is that strength × 15 litres. Seed treatments are per kg of seed. Where a figure cannot be read safely, the card says “see the government figures below”. Sources: Central Insecticides Board and Registration Committee, Directorate of Plant Protection, Quarantine and Storage: Major uses of pesticides (registered under the Insecticides Act, 1968), Insecticides, up to 30.09.2026, based on certificates issued; CIB&RC bio-insecticides as on 30 September 2026. Brands: linked names are from each company's own website (the link opens it), matched to the exact chemical, strength and form in the lists; names with ⓘ are from trade listings, checked by web search, not yet confirmed by the company. Large companies are listed first; the order is not a ranking, and NanoKheti does not sell pesticides or take money from any company. The lists say: “The document has been compiled on the basis of available information for guidance and not for legal purposes.”
