Managing Moisture:
- Keep soil moisture at a level that prevents plant stress.
- Avoid too much moisture, which can reduce the effectiveness of harvest aids.
- If dealing with drought, add surfactants to help harvest aids work better [1].
Once you’ve nailed the timing and accounted for weather, using harvest aids correctly can help minimize losses and boost your yield.
3. Use Harvest Aids Effectively
Applying harvest aids correctly is key to getting your cotton crop ready for mechanical harvesting and reducing yield loss. These chemicals help by ensuring bolls open evenly and leaves drop uniformly.
3.1 Apply Harvest Aids at the Right Temperature
Harvest aids work best when applied at temperatures above 60°F, ideally 10-14 days before harvest. If your crop is under drought stress or facing high humidity, you might need to extend this window to allow for complete defoliation.
Here’s how to get the best results:
- Check the weather forecast to find the ideal application period.
- Use surfactants for drought-stressed cotton to improve chemical absorption.
- Monitor field conditions to ensure the chemicals activate properly.
3.2 Choose the Right Application Tools
For effective coverage, use flat-fan or hollow-cone nozzles, apply at least 15 gallons of spray per acre, and ensure the spray pattern overlaps evenly. Regularly calibrate your equipment and clean the nozzles to maintain consistent application.
| Equipment Component | Recommended Specifications | Purpose |
|---|---|---|
| Nozzle Type | Flat-fan or hollow-cone | Distributes spray evenly across the canopy |
| Carrier Volume | Minimum 15 gallons per acre | Ensures thorough coverage |
| Spray Pattern | Uniform overlap | Avoids missed areas and uneven defoliation |
Make sure the harvest aids reach all parts of the plant for complete defoliation. Apply them after the plant has reached 'cutout' - when growth has stopped - to protect fiber quality and minimize losses [1]. Proper application also reduces trash content and ensures a smoother, more uniform harvest.
Once your harvest aids are applied, you’ll be ready to prepare the fields for efficient harvesting.
