NoFly WP Biological Insecticide for Greenhouse and Nursery Crops
The active ingredient here is Isaria fumosorosea strain FE 9901, a naturally occurring fungus formulated as a wettable powder. It infects insects through contact rather than through feeding. On the foliage, it is labeled against aphids, leafhoppers, mealybugs, plant bugs, spider mites, thrips and whiteflies. Below the soil line, the list changes to root aphids, root mealybugs, caterpillars and the pupal stage of thrips. That second group is hard to reach with a leaf spray. Labeled crops include ornamentals plus many herbs, fruits and vegetables grown in containers. Greenhouses, hydroponic systems and nurseries are all covered, along with field-grown nursery stock. The 12-hour REI sets the re-entry window after each treatment. OMRI listing keeps it open to certified organic growers.
Mixing and Timing for Organic Whitefly Control
Rates run 6 tsp per gallon, or 14 to 28 oz per 100 gallons, for both foliar and drench work. Soil pests can also be treated by blending the powder into the media before planting. Spray coverage needs to reach the leaf undersides, where whitefly nymphs settle. Fungal products build slowly, so begin while counts are low. Sticky cards give an early read on when adults are arriving. Humid rooms generally favor infection, so match spray timing to the climate in the space. Avoid tank mixing with fungicides unless the label allows it. Keep the bag between 34 and 72°F, and refrigerate it when possible. Live spores lose strength in a hot shed. Mix only what the day's spray will use.
