BT NOW Insecticide
BioSafe Systems announces the release of BT NOW, an aqueous, biological insecticide labeled to control various Lepidoptera pests in a wide variety of crops. Its formula consists of Bacillus thuringiensis ssp. kurstaki (Btk) strain EVB-113-19, a new variation of the Btk bacterium that targets the Lepidoptera insect while being easy on many beneficials and pollinators. This specialized Btk strain makes BT NOW a highly effective resistance management tool that is compatible with many commonly used pesticides, fertilizers and adjuvants.
Within hours of application, the effected young pests will cease feeding and die from starvation in two to five days. BT NOW works by providing insecticidal endotoxins called cry toxins that disperse in the pest’s digestive tract. These toxins bind to the insect’s midgut receptors, immediately disrupting and paralyzing certain digestive functions. Feeding stops soon after application of BT NOW, ensuring the longevity of the crop under heavy Lepidoptera pest pressure.

As a pesticide active ingredient, the extract does not harm humans, non-target organisms or the environment. NemOMEX is 100 percent soluble at recommended usage rates and can be applied by ground spray, shank injection or chemigation.
NemOMEX nematode management has shown and continues to show variability in nematode mortality rate depending on the ecological system, which includes plant-parasitic species and population size, plant, climate and soil environments, along with relationships between free/beneficial nematode populations.

Embrece-EA Surfactant
Embrece-EA is a unique blend of surfactants designed to elevate the performance of fungicides, insecticides and miticides by increasing wetting and spreading of spray materials.
Embrece-EA’s proprietary blend of nonionic surfactants (NIS) gives growers superior coverage and excellent wetting of their chosen spray material, meaning more product stays on the leaf surface, providing quicker absorption and improved control of the targeted pest. In addition to increased performance, Embrece-EA offers growers more safety and peace of mind while allowing for more application flexibility dependent on the crop grown. A lower use rate (1 pint per 100 gallons) is ideal for cover sprays, while higher use rates (1quart 100 gallons) provides more penetration. The product also works well with difficult formulations, like soluble concentrates, and gives growers a safer alternative to similar adjuvants.
Embrece-EA is part of Wilbur-Ellis’s Eco Advantage line of products. Every Eco Advantage adjuvant is labeled for aquatic use, is made with ingredients for improved safety and handling, and is nonylphenol ethoxylates-free. Embrece-EA boasts lower phytotoxicity concerns than traditional adjuvants, as well as lower toxicity concerns for humans and the environment.

PREV-AM
PREV-AM is a three-in-one insecticide, fungicide and miticide. It is a contact pesticide that can be applied throughout the season without danger of resistance buildup and is perfect for controlling pre-harvest insect and disease infestations. With a short REI and PHI, PREV-AM is a versatile alternative to conventional pesticides and is ideal for IPM and sustainable farming practices.
The desiccating properties of PREV-AM result in quick knockdown of insects and mites, typically within two to 24 hours. The water-repellent layer protecting most insects loses its effectiveness when contacted by a PREV-AM application. This allows the active ingredient to penetrate and destroy the soft, living tissues underneath. The insects and mites are then exposed to the loss of body fluids, causing death.
As a fungicide, the PREV-AM spray solution breaks down the protective membranes of the superficial fungal mycelia (hyphae) and spores, allowing the active ingredient to penetrate and destroy the living tissues underneath. This exposes the organism to the drying effect of the atmosphere and causes collapse within two to 24 hours. Plant tissue damaged by the fungus may also dry out and prevent further spread of infection, but healthy tissue is not affected at the recommended application rate.
