Whitefly (Type Q) Results with New MOA Technology Product - PREV-AM

Share Article

ORO AGRI International has just released their latest Whitefly (Bemisia tabaci) Type Q results this week at the International Society For Horticultrual Science Symposium 2006. PREV-AM, a broad spectrum Fungicide & Insecticide in one product, has been proven to provide a technology knock-out punch to whitefly (Type Q). (Independent Research).

In the independent research, PREV-AM performed exceptionally well for control of Whitefly (Bemisia tabaci) Type Q on tomatoes and zucchini. On the tomato trials, PREV-AM was compared against lambda-cyhalothrin products and was able to attain a 48% initial higher efficacy rate than the lambda-cyhalothrin and a 25% better larvae efficacy rate over the duration of the study. The highest control rate attained on larvae was in excess of 90%.

PREV-AM also performed well against buprofezin products and was able to attain a 13% initial higher larvae kill rate than the buprofezin and a 12% better larvae efficacy kill rate over the study duration. When PREV-AM was applied on Zucchini, PREV-AM attained 31% initial higher larvae kill rate than the buprofezin and ultimately a 99.06% control on the final application.

According to Tomas Hoppe (Phd), an entomologist and presenter of the data "PREV-AM performs on contact with the insects or pathogens by attacking the exoskeletons of Egg-2-Adult™ and Spore-2-hyphae™ stages of insects and diseases, but has no residual effect making it an ideal IPM tool."

Tomas further states that PREV-AM can be used as either a stand-alone, alternating or in combination with other insecticides or fungicides. In other studies, when combined with other insecticide and fungicide products in tank mixes, the 2 Mode-Of-Action approach typically performed much better together than they do alone.

When PREV-AM is added to a tank-mix, PREV-AM provides the initial and immediate physical control effect on insects and fungi. The systemic and or translaminar product then has a physically weakened and smaller remaining population to attack.

Tomas further states that these multiple 100+ page studies (using GAP standards) are consistent with what we have seen in more than 200 independent studies across various vegetable, fruit, nut, and soybean crops. PREV-AM is an EPA registered product for control of such insects as Aphids, Mites, Thrips, Scale, Worms, Whitefly and more. PREV-AM is also, an EPA registered fungicide for control of Blights, Mildews, Rots, Rusts and more.

About Whitefly Type Q

Whiteflies (type B) resulted in US crop losses of more than $2 billion. [ http://news.ucanr.org/newsstorymain.cfm?story=342 . Globally, the number is much higher. With the advent of nicotinoids, the threat was minimized. Recently however, the newer pesticide resistant Whitefly Bemisia tabaci type Q has emerged and may pose the same initial treat to global crops as type B initially did.
