• Low formulation rate: all three registered rows use 150 g formulation/ha, equal to 127.5 g active ingredient/ha.
• Defined water guidance: PPQS lists 500 L water/ha, while PI states 200 L water/acre for soil-surface coverage.

Toxicity Marking

Blue triangle; PI states moderately toxic and the caution word “Danger”

PI explains that Pyroxasulfone reduces the biosynthesis of very-long-chain fatty acids and inhibits elongation steps catalysed by VLCFA elongases. These fatty acids are important to normal growth of emerging weed seedlings. The product is consequently used on the soil before the registered weeds emerge.

HRAC Global places Pyroxasulfone in Group 15, with legacy code K3. A mode-of-action number supports resistance planning but is not itself an application recommendation. Avoid repeated reliance on one group. Where a different herbicide is agronomically required, use a separately applied product whose own Indian label covers the crop, weed and application stage. No recommendation on this page is a tank-mix instruction.

PHI = pre-harvest interval. All three PPQS rows state 127.5 g active ingredient/ha and 150 g formulation/ha. PI states 200 L water/acre. Retain the official units and do not invent a universal pump or per-litre dose.

• Apply within 0–3 days of sowing to a uniform, well-prepared field that is free from large clods and residues of the previous crop.
• Use a knapsack sprayer or suitable boom fitted with a flat-fan nozzle and obtain even coverage of the soil surface.
• Use the recommended water quantity. PI states 200 L/acre and advises the first irrigation at 21 days after sowing for all soil types.
• Do not apply during high wind. PI also advises against walking on the wet field after irrigation because disturbed soil can permit weed germination.
• Do not use metallic utensils to prepare the stock solution. Do not apply Awkira as a sand mix or fertiliser mix.

• PI directs users to wear a mask, goggles, gloves, boots and other proper protective clothing while handling and applying the product.
• Do not eat, drink or smoke during application. Wash hands and contaminated clothing with soap and plenty of water afterwards.
• Avoid contamination of air and water bodies. Store and dispose of the product and empty pack exactly as the current label directs.
• PI states that no specific antidote is known and symptomatic treatment should be provided. In an exposure incident, seek medical help and show the current label.

Always read and follow the current PI Industries Awkira label and leaflet. They are the final authority for registered crops and weeds, dose, water volume, timing, equipment, PPE, first aid, storage, re-entry, compatibility, disposal and PHI.
