OHP Inc. today announced the immediate availability of a new and improved formulation of its Azatin biological insecticide.
Azatin O Biological Insecticide, the latest addition to the OHP product portfolio, replaces Azatin XL and features several upgrades, including:
• OMRI Listed (Organic Materials Review Institute) – can be used in organic production, and can be applied up to and including the day of harvest (0 day PHI);
• Registration in New York and California and all other states;
• The highest concentration of azadirachtin available – 4.5 percent for Azatin O vs. 3.0 percent or less for competitive products;
• 175 grams of azadirachtin per gallon, compared to 128 grams or less for competitive products;
• Rate flexibility compared to competitive products
Azatin O can be used for broad-spectrum insect control on ornamentals, fruit and vegetables including berries, herbs, and spices.
An insect growth regulator (IGR), Azatin O controls the larval stage of many tough pests such as aphids, thrips, whiteflies, scale, grubs, borers, stink bugs, chafers, grasshoppers, leafhoppers, psyllids, and many Lepidoptera species.
Azatin O is compatible with most beneficial insects.
OHP will maintain Azatin XL federal and state registrations for a period of time so growers can deplete their inventories. Azatin O is packaged in a quart bottle and carries a 4-hour Restricted Entry Interval (REI).
