Syngenta has released a technical bulletin for a new fungicide called Micora in the ornamental markets. The active ingredient, Mandipropamid, is in MOA class 40, the Carboxylic Acid Amides. This chemistry will have protectant and contact control and translaminar activity into the leaf cuticle. Micora provides long residual control of labeled diseases Phytophthora and Downy Mildew. Foliar and drench rates are a low 4-8 oz/100 gals. Low volatility and low to medium mobility in the soil will make this a good tool in controlling soil borne Phytophthora pathogens.

I also picked up a technical bulletin from Syngenta for their new insecticide called Enfold. Enfold is an insecticide that is highly effective against caterpillars, leafminers, spider mites and pear psylla. Enfold will be available in a soluble granule form, and is in the Avermectin or MOA Class 6 fungicide group. The active ingredient is Emamectin benzoate and can be applied at a low rate of 2.4-4.8 oz/100 gals. Enfold has some contact activity but works best after the insect ingests the active ingredient. Testing has indicated that Enfold is safe to use around many beneficial insects, and can be compatible with sound IPM practices.

Hurricane has been reformulated into a WDG (water dispersible granule). From personal previous use with the old water dispersible bags, this new formulation should help growers with ease of mixing and should also help to keep mixing dust to a minimum. Another great feature with the new WDG, is that growers are now no longer required to tank mix, so no more adding Medallion for soil drenches. New packaging comes in an 8 oz container and application rates are very low at 0.75oz/100 gallons on seedlings and up to 1.5oz/100 gals on cuttings and transplants. Hurricane still controls the same labeled diseases including Pythium, Phytophthora, and Rhizoctonia.

The SePro Corporation has announced the registration of its’ new biological insecticide Preferal. Preferal contains the natural occurring fungal strain, Isaria fumosoroseus which was first isolated by Dr. Lance Osborne at the U of FL. Preferal is effective at controlling aphids, whitefly, thrips and spider mites. This water dispersible granule has been used in IPM programs in Europe for some time now with good success, and is compatible with most beneficial insects.
