Mycostop WP Biological Fungicide from MGS Horticultural
Mycostop WP from MGS Horticultural controls many root-borne diseases, including seed rot, root and stem rots and wilt caused by Fusarium, Alternaria and Phomopsis of container-grown ornamentals, vegetables and tree and forest seedlings. Mycostop has also shown suppression of Botrytis gray mold and root rots of Pythium, Phytophthora and Rhizoctonia. Mycostop WP is a bacteria (Streptomyces strain K61) that has many advantages over other fungicides, as it will work well in cooler temperatures. It also excels under higher heat, when plants are under most root disease pressure. The product has a 0-hour postharvest interval and a 4-hour re-entry interval.
Aphid Guard from IPM Labs
Aphid banker plants from IPM Labs produce a constant supply of aphids, which in turn support continuous reproduction of aphid parasites and the aphid midge. Greenhouse growers benefit by having a reproducing natural enemy population in the greenhouse that can find and attack pest aphids on the crop as soon as they appear. It also reduces their costs for regular shipments of natural enemies via overnight freight. Aphid Guard consists of densely seeded young barley plants infested with the bird cherry-oat aphid, Rhopalosiphon padi. These aphids do not attack broad-leaved plants.
NoFly WP from Natural Industries
NoFly WP from Natural Industries is labeled for use in controlling whitefly, aphids, thrips, mealybugs and fungus gnats on non-food crops and ornamentals in greenhouses. The NoFly WP formulation contains spores of Paecilomyces fumosoroseus strain FE 9901. This microorganism is a naturally occurring fungus and a common pathogen of insect pests. Applied through all stages of the pest’s lifecycle, NoFly WP is particularly rapid with first symptoms of infection, which are apparent within 24 to 48 hours after the conidia is in contact with the insect.
