Iris Borer

Iris Borer Description: Eggs overwinter in stems of iris and other debris. After eggs hatch they must crawl to the base of the iris to bore into stems. During this migration they are susceptible to Grub-Away Nematodes. Infested leaves are yellow from the tip back, have notches on the edge; plants lose vigor; many fail to bloom. Solution: Grub-Away Nematodes […]

Halo Blight (Beans)

Halo Blight (Beans) Description: Symptoms of halo blight start as small watersoaked spots on leaves, which gradually turn dark brown. The spots remain small and become surrounded by a wide yellow-green halo. The spread and development of halo blight is favored by wet weather and plant injury from rain, hail, people or equipment. Halo blight develops best when temperatures are […]

Gypsy Moth – How to Control

The most characteristic sign of gray mold is its fuzzy, felt-like appearance. Solution: If gray mold has been a problem in past years, begin spraying Soap-Shield® Fungicidal Soap at time […]

Gray Mold (Beans)

Gray Mold (Beans) Description: Gray mold is most common when flowering occurs during a cool period of high humidity. Crowded plants with a dense canopy of leaves also encourage gray mold.

Fusarium Wilt (Cucurbits)

Fusarium Wilt (Cucurbits) Description: In young melon, cucumber and watermelon plants: damping-off, stem collapse, and death. In older plants: yellowing, stunting, wilting, and death. The disease is established wherever cucurbits are grown. Solution: Maintain soil pH at 6.5 to 7.0. Test soil pH; if it is too acid, use ground limestone to raise pH. Most garden centers and farm stores […]
