Frequently Asked Questions

Why did VIT decided to add NEEMAZAL®–T/S, an azadirachtin product, to it's product line?

VIT-Verim is distributing highest quality products for organic agriculture since 18 years. And Trifolio-M GmbH (Germany) is manufacturing a quality organic insecticide NeemAzal-T/S. The combined partnership of Trifolio-M and VIT-Verim ensures technical expertise and common-sense experience for the Turkish growers. VIT-Verim provides more then sales support to wide range people, from farmers to academic people in organic farming.

What is the mode of action of NEEMAZAL®–T/S?

NEEMAZAL®–T/S, protects plants by acting on the insect pest in multiple ways. Feeding deterrence, repellency, growth regulation, and contact toxicity are the primary means of managing pest insect populations. Of these methods, contact toxicity is the least expressed method of control.

Wouldn't one be better off buying the higher percent concentration products instead of NEEMAZAL®–T/S with %1 azadirachtin?

No. Higher concentration of technical is only one aspect of the product. Products derived from biological sources are often unstable. Storage stability can be compromised by the inclusion of fats, esters, water, and other ingredients in the technical material. Additionally, azadirachtin is quickly broken down in nature by UV light and other common elements.

What makes NEEMAZAL®–T/S a more effective formulation of azadirachtin?

The refined extraction process, the natural oil and food grade emulsifier in NEEMAZAL®–T/S not only enhance the stability of the product but also help in absorption into the leaf tissues resulting in translaminar activity which is especially important for control of such pests as dipteran leaf miners

Does NEEMAZAL®–T/S have any effect on adult insects?

Direct effects on adult insects include repellency and feeding deterrence. Some soft-bodied insects such as aphids may exhibit mortality from direct exposure to NEEMAZAL®–T/S. In order for growth regulation to manifest itself in insects, the insect must be in a juvenile stage (larva or nymph) and must ingest NEEMAZAL®–T/S.

NEEMAZAL®–T/S is touted as a superior azadirachtin formulation, but aren't all azadirachtin products alike?

Products registered as biological insecticides containing extracts from the neem tree must contain azadirachtin. Constituents of the neem seed include oil, azadirachtin (several analogues), and other bioactive limonoids. NEEMAZAL®–T/S is formulated with the highest quality technical grade azadirachtin available. The azadirachtin in NEEMAZAL®–T/S is extracted using an eco-friendly solvent in a patented process. The resulting technical material has low oil, ester, and water content resulting in a very stable product that exhibits long shelf life. Extremely low levels of impurities and the highest levels of bioactive molecules including azadirachtin, nimbin, salanin, and characterized and non-characterized limonoids result in a superior technical material.

But NEEMAZAL®–T/S is only a 1% product how can you say you have the highest purity technical and yet be only 27 to 40 percent of the azadirachtin concentration of competitive products?

It is not uncommon to confuse the concepts of purity and concentration. Purity refers to the quality of the individual components of the active ingredient and concentration refers to the quantity of the active ingredient that is diluted with carrier materials that allow practical use of the product. These carriers are often emulsifiers and oils that enhance the activity (act as synergists) of the active ingredient. If one compares the effective rates of NEEMAZAL®–T/S to competitive azadirachtin products, NEEMAZAL®–T/S exhibits equal or greater biological efficacy on a per pound azadirachtin-to-azadirachtin basis. The recommended rates of the NEEMAZAL®–T/S formulation are higher than competitive products to compensate for lower concentration of azadirachtin, but this increase use rate is offset because lesser or no quantity of additional crop oil is needed.
