Winning the Battle Against Nematodes in Root Crops

In root crops, what happens below the surface can make or break a season. Soilborne diseases, nematodes, and weeds don’t just compete — they compound, creating hidden pressure that’s difficult to reverse once it takes hold.

Winning the Battle Against Nematodes in Root Crops Targeted monitoring, species-specific management, and integrated control strategies help growers reduce nematode pressure and protect root crop yields.

Bell peppers are already mild, so the last thing they need is to turn up the heat! OASIS and OASIS O are calcium carbonate-based solar protectants that keep bell peppers mild in every sense of the word, shielding them from sunburn and heat stress during the hottest parts of the growing season.

OASIS cools your crops by refracting and diffusing incoming sunlight, reducing tissue temperatures and limiting sun damage to the fruit. The result is better water use efficiency, improved photosynthetic performance, and a higher-quality harvest with less crop loss to overexposure.

Citrus trees have enough to deal with come summer; the sun should work for, not against, them. OASIS foliar-applied calcium carbonate formula is designed to protect citrus from sunburn and heat stress, giving growers a practical way to manage what the sun throws at their trees.

OASIS (and OMRI-listed OASIS O) refracts and diffuses sunlight, softening intensity before it can damage plant tissue. Reduced sunburn, improved photosynthetic efficiency, and better water use add up to healthier trees and better yields when harvest time comes.
