We help cotton growers
manage their toughest problems.
Cotton growers face some tough weed problems. Weeds like pigweed and marestail that become even nastier when compounded by resistance to select herbicides. MANA Crop Protection has a portfolio of products to help you clean house.
Using the proven residual power of Cotoran® 4L, Cotton Pro®, Direx® 4L, Pyrimax® 3.2L and Triflurex® HFP you can take control of even the toughest resistant weeds in your cotton.
These products are part of a proactive, season-long weed control plan that includes:
- Use of residual herbicides
- Rotation of different modes of action
- Weed control on surrounding non-crop ground
- Crop rotation
- Use of tillage and cultivation practices
For questions, talk to your crop consultant, retailer or a MANA cotton specialist.

Aggressive Management For Success
|
Diversify your weed management approach for success
Diversity can be achieved by using mechanical and cultural tactics in addition to herbicides with different modes of action and overlapping control.
Apply multiple herbicides with different modes of action, including residual herbicides.
- Methods to apply herbicides with different MOAs:
- Mixture application
- Sequential through the season
- Across multiple seasons
- Overlap residual control and do not leave gaps in control by allowing the activity of your herbicide to exceed its residual period; overlap herbicides to ensure uninterrupted activity on target weeds
- Apply herbicides at the correct labeled rate and timing
|
Mechanical tactics can include:
- Tillage, which can remove existing weeds and bury weed seeds below germination levels
- Pre-plant
- In-season
- Post-harvest
- Hand removal of weeds
|
Incorporating different agronomic practices into a weed control program may influence the growth cycle of weed species and give an advantage to the crop. Tactics may include:
- Crop rotation, which allows use of herbicides with different modes of action, change in planting dates, use of different fertilizer practices and tillage techniques; utilizing natural differences exist in crops’ abilities to compete with weeds
- Hybrid selection, including use of certified, weed-free seed
- Plant population and row spacing
- Harvest techniques
- Planting a cover crop
- Controlling weeds in surrounding areas
- Cleaning equipment to minimize spread of herbicide-resistant weeds and weed seeds
- Managing weeds in areas bordering fields
|
Understanding the biology of the weeds you are fighting is critical to your resistance management program. While utilizing the different techniques mentioned on this page to stay ahead of weed resistance, always remember to:
- Scout regularly to identify weeds present in fields
- Respond quickly to changes in weed populations
- Modify management practices to stop the spread of resistant weeds
