Carwoodi Nematode Control Radish

Protect your crops from nematodes with phytochemicals.


Carwoodi Nematode Control Radish (Raphanus sativus) releases a biochemical from its roots that stimulates cyst nematode eggs to hatch prematurely. The nematodes then attach to the radish root but are unable to adequately feed. Because the radish does not provide the nutrition they need, the nematodes either die or do not reproduce. Nematode controlling radish are bred to provide maximum control for targeted species of nematodes. Carwoodi is effective at controlling Columbia Root Knot nematodes. It is critical that nematode controlling radishes are not planted in mixes with species that are known or suspected of being a nematode host.

Forage Quality Ability to improve forage quality by suppressing weeds and providing highly nutritious forage  
Nutrient Recycling Ability to store excess nutrients for use in subsequent cash crops  
Quick Growth Ability to increase soil organic matter by accumulating biomass in a short period of time  
Weed Suppression Ability to suppress weeds by shading soil and releasing allelopathic chemicals  
Nitrogen Fixation Ability to fix nitrogen into your soil for your subsequent cash crops to utilize as fertilizer for growth and energy  
Beneficial Insectary Ability to attract beneficial insects and reduce your reliance on costly insecticides  
Soil Compaction Ability to increase nutrient uptake and root development by breaking up dense and compacted soil  
Erosion Control Ability to hold soil in place to capture and retain moisture from rainfall and prevent topsoil erosion  
Water Management Ability to increase field productivity by improving the drainage of wet soils  
Heat Ability to tolerate heat stress caused by warm temperatures and/or limited water availability  
Drought Ability to tolerate periods of limited water availability  
Sub-Freezing Ability to tolerate freezing temperatures for an extended period of time  
Shade Ability to tolerate low light conditions caused by plant competition  
Flood Ability to tolerate standing water or flooded areas for a limited period of time  
Low Fertility Ability to tolerate soils with limited nitrogen, and other mineral resources necessary for growth
