LUMA™ PLUS reduces surface tension of the spray droplet on the leaves and cuts through leaf waxes on the target species. It stimulates the plant, opening the stomata to absorb the spray quickly and completely. It reduces the need for additional spraying should rain occur, thus decreasing the chance of contaminating run-off. In addition, it allows spraying to be done at 10 to 12 degrees higher or lower than the normal product temperature ranges permit.
