Control weeds effectively with herbicides (weedicides) from KrishiDukan. Weeds are the single most costly pest category in Indian agriculture — weed competition during the first 30–45 days after sowing or transplanting can reduce yields by 20–60% depending on weed species density and the crop. Choosing the right herbicide and applying it at the correct growth stage is as important an agronomic decision as seed or fertilizer choice.

KrishiDukan lists selective and non-selective herbicides for both pre-emergence and post-emergence use. Pre-emergence herbicides are applied to moist soil immediately after sowing and before crop or weed emergence. They form a chemical barrier in the upper soil layer that prevents weed seedlings from establishing. Most pre-emergence herbicides require a light rainfall or irrigation within 3–4 days of application to activate them. Post-emergence herbicides are applied after both crop and weeds have emerged and must be matched precisely to the weed species present: narrow-leaved (grass) weeds like Echinochloa, Phalaris and Digitaria; broad-leaved weeds like Parthenium, Chenopodium, Convolvulus and Commelina; or sedges like Cyperus rotundus (nutgrass, motha).

Herbicide selectivity is crop-specific. An herbicide safe on wheat may damage soybean, and one registered for paddy may not be approved for maize. Always confirm that the product label lists your crop before application. Every KrishiDukan herbicide listing includes the active ingredient, chemical family, weed spectrum covered, application timing, recommended dose per acre and per litre of water, required water volume, crop safety notes, re-entry interval and PHI.

Popular products available include: for pre-emergence — pendimethalin 30% EC, atrazine 50% WP, butachlor 50% EC, metolachlor, alachlor and metribuzin; for post-emergence on wheat — clodinafop-propargyl + metsulfuron, sulfosulfuron, isoproturon; for paddy — bispyribac-sodium (Nominee), pretilachlor, oxadiargyl, cyhalofop-butyl; for soybean — imazethapyr, quizalofop-p-ethyl, fenoxaprop-p-ethyl; for cotton and maize — 2,4-D, tembotrione, topramezone, nicosulfuron.

Herbicide resistance is increasing in India, particularly Phalaris minor resistance to ACCase inhibitors in wheat-growing states. Rotating herbicide modes of action across seasons — using HRAC group A (ACCase inhibitors) one year and HRAC group B (ALS inhibitors) the next — is the recommended management strategy. Spray using a flat fan nozzle calibrated to deliver 150–200 litres of water per acre, avoid application in windy conditions to prevent drift, and observe the sprayer exclusion zone near field boundaries, water sources and sensitive crops.
