Question 1

What is Weedout Super Herbicide used for?

Accepted Answer

Weedout Super Herbicide is a post-emergence selective combination herbicide specifically formulated for cotton crop weed management. It effectively controls both broadleaf weeds (through Pyrithiobac Sodium) and grassy weeds (through Quizalofop Ethyl) in a single spray application, keeping cotton fields weed-free for 25-30 days and supporting maximum crop yield potential through effective weed competition management.

Question 2

What is Weedout Super dose per litre?

Accepted Answer

The recommended Weedout Super dose per litre is around 5 ml per litre of clean water for post-emergence spray application in cotton. Add the required product to the sprayer tank filled with clean water, mix thoroughly, use flat fan nozzle for uniform coverage, and spray directly on weeds (avoid direct cotton crop hit) during cool morning or evening hours for maximum weed control efficacy.

Question 3

How does Pyrithiobac Sodium 6% + Quizalofop Ethyl 4% MEC work?

Accepted Answer

Pyrithiobac Sodium 6% + Quizalofop Ethyl 4% MEC works through dual mode of action attacking both broadleaf and grassy weeds simultaneously. Pyrithiobac Sodium (HRAC 2 ALS inhibitor) blocks amino acid biosynthesis in broadleaf weeds, while Quizalofop Ethyl (HRAC 1 ACCase inhibitor) blocks fatty acid biosynthesis in grassy weeds. This selective dual attack controls diverse weed species without harming cotton crop.

Question 4

What is Weedout Super Herbicide dose per acre?

Accepted Answer

The recommended Weedout Super Herbicide dose per acre is around 1 litre per acre, mixed in about 200 litres of clean water for uniform post-emergence spray application. Apply when weeds are at 2-4 leaf stage (15-25 days after cotton sowing) for maximum weed control efficacy. Use flat fan nozzle with directed spray targeting weeds while avoiding direct hit on cotton growing points for crop safety.

Question 5

Which weeds does Weedout Super control in cotton?

Accepted Answer

Weedout Super effectively controls both broadleaf weeds (Digera arvensis, Amaranthus, Trianthema, Portulaca, Boerhavia) and grassy weeds (Echinochloa colona, Eleusine indica, Dactyloctenium, Cynodon, Cyperus in early stages) in cotton fields. The dual-mode combination gives broad-spectrum weed knockdown at single spray application, saving multiple herbicide applications and giving effective 25-30 day weed-free period during critical early cotton crop growth stage.

Question 6

Is Pyrithiobac Sodium 6% + Quizalofop Ethyl 4% MEC selective to cotton?

Accepted Answer

Yes, Pyrithiobac Sodium 6% + Quizalofop Ethyl 4% MEC is a selective post-emergence herbicide specifically formulated for use in cotton crop. Both active ingredients are safe on cotton when applied at recommended dose (1 litre per acre) at right growth stage. Cotton has natural tolerance mechanisms to metabolize these herbicide chemistries. Avoid application under stress conditions and follow proper spray techniques for maximum crop safety.

Question 7

When should Weedout Super be applied in cotton?

Accepted Answer

The best application timing for Weedout Super in cotton is 15 to 25 days after sowing when weeds are at 2-4 leaf stage and cotton crop is at 4-6 leaf stage. Apply as post-emergence directed spray between crop rows targeting weeds while minimizing direct hit on cotton growing points. Avoid application during peak sun hours, wet foliage conditions, or when rainfall is expected within 4-6 hours after spray.

Question 8

Does Weedout Super Herbicide affect rotational crops?

Accepted Answer

Weedout Super Herbicide has moderate residual activity in soil, and rotational crop planning should consider a 30-45 day interval before sowing sensitive crops (pulses, sunflower, groundnut) in same field. Cereals (wheat, paddy) and cotton itself can be planted after normal harvest interval without concerns. Always follow specific product label recommendations for rotational crop planting intervals based on your regional soil and climate conditions.

Question 9

Can Pyrithiobac Sodium 6% + Quizalofop Ethyl 4% MEC control Cyperus in cotton?

Accepted Answer

Pyrithiobac Sodium 6% + Quizalofop Ethyl 4% MEC provides suppression of Cyperus rotundus (nutgrass/motha) at very early emergence stage (1-2 leaf), though established Cyperus with well-developed tubers may show only partial control. For heavy Cyperus infestation in cotton, integrate with pre-emergence herbicide, mechanical hand-weeding of established nutgrass tubers, and follow-up spray applications. Cyperus is one of the toughest weeds to control in Indian cotton cultivation.

Question 10

What is best spray technique for Weedout Super?

Accepted Answer

The best spray technique for Weedout Super is post-emergence directed spray using flat fan nozzle with knapsack sprayer, targeting weeds between cotton rows while minimizing direct hit on cotton growing points. Maintain uniform spray pressure (1-2 kg/cm²), consistent walking speed for even coverage, use 200 litres water per acre spray volume, and apply during cool morning (7-10 AM) or evening (4-7 PM) hours for maximum efficacy.

Question 11

Does Pyrithiobac Sodium 6% + Quizalofop Ethyl 4% MEC require adjuvant?

Accepted Answer

Pyrithiobac Sodium 6% + Quizalofop Ethyl 4% MEC formulation typically includes built-in surfactant/adjuvant for good leaf coverage without additional adjuvant requirement. However, for hard-to-kill weeds or waxy weed surfaces, adding a silicon-based spreader at 0.5 ml per litre may improve weed control results. Always check product label recommendations before adding external adjuvants to avoid compatibility issues or phytotoxicity concerns.

Question 12

Is Weedout Super compatible with insecticides?

Accepted Answer

Weedout Super is generally NOT recommended for tank-mix with other herbicides, insecticides, or fungicides due to potential compatibility issues and possible reduction in weed control efficacy. Apply Weedout Super separately as a stand-alone spray application for maximum weed control results. Allow 5-7 days interval before or after other pesticide sprays in the cotton crop. Follow label recommendations strictly.

Question 13

How long does Weedout Super give weed control?

Accepted Answer

Weedout Super Herbicide provides effective weed-free period of 25 to 30 days after post-emergence application in cotton crop, covering the critical early crop growth stage where weed competition causes maximum yield losses. This extended weed-free period supports strong cotton canopy establishment, allowing the crop to smother subsequent weed emergence through natural crop canopy coverage. Follow-up hand weeding may be needed later in the season.

Question 14

Does Pyrithiobac Sodium 6% + Quizalofop Ethyl 4% MEC improve cotton yield?

Accepted Answer

Yes, Pyrithiobac Sodium 6% + Quizalofop Ethyl 4% MEC significantly improves cotton yield by 20-35% through effective early-season weed management that eliminates competition for water, nutrients, sunlight, and space during critical crop establishment period. Weeds are estimated to reduce cotton yield by 30-60% if not managed effectively. Post-emergence application at right stage gives clean weed-free field for optimal cotton growth, canopy development, and maximum bolls production per plant.

Question 15

How to store Weedout Super Herbicide properly?

Accepted Answer

Store Weedout Super Herbicide in its original sealed container in a cool, dry, well-ventilated place away from direct sunlight, extreme heat, and freezing conditions. Keep the cap tightly closed after use to prevent contamination and evaporation. Store separately from food, animal feed, and drinking water sources. Keep out of reach of children, pets, and unauthorized persons. Preferred storage temperature is below 30°C for optimal product stability.
