Trasco Neemazin
Trasco Neemazin Dust (Azadirachtin based pure Neem cake Powder)

Introduction
The key insecticidal ingredient found in the neem tree is azadirachtin, a naturally occurring substance that belongs to an organic molecule class called tetranortriterpenoids. It is structurally similar to insect hormones called "ecdysones," which control the process of metamorphosis as the insects pass from larva to pupa to adult. Metamorphosis requires the careful synchrony of many hormones and other physiological changes to be successful, and azadirachtin seems to be an "ecdysone blocker." It blocks the insect's production and release of these vital hormones. Insects then will not molt, thus breaking their life cycle. Azadirachtin may also serve as a feeding deterrent for some insects. Depending on the stage of life-cycle, insect death may not occur for several days. However, upon ingestion of minute quantities, insects become quiescent and stop feeding. Residual insecticidal activity is evident for 7 to 10 days or longer, depending on insect and application rate. Azadirachtin is used to control whiteflies, aphids, thrips, fungus gnats, caterpillars, beetles, mushroom flies, mealybugs, leafminers, gypsy moths and others on food, greenhouse crops, ornamentals and turf.

Target crops: Cereals,Pulses,Plantation crops like Tea ,Coffee,Vegetables,Fruit crops,Medicinal plants, Flowers of all types ,Orchids etc

Classification and mode of action: TRASCO Neemazin Dust is a potential Neem based powder used as a urea coating agent, Also has soil based systemic insecticidal properties.

Product Potential: Farmers can use Trasco Neemazin dust as urea coating agent.

Farmers apply urea to their fields in large quantities forgetting that this applied urea is not fully utilized by the plant. On an average about 30% of the applied Nitrogen is lost due to leaching in the fields due to non absorption. The conversion rate of amide nitrogen to nitrate nitrogen is so high that the plants cannot assimilate the same quickly.

The application of Neemazin dust to urea by coating the same at a proper rate ensures that the urea is slowly converted to nitrate nitrogen for complete uptake by the plant.

The nitrifying bacterias action slows down due to application of neem to urea. The urea thus is slowly converted to available nitrogen for the plants. Thus the fertilizer use efficiency is brought upto 100%.

Ecological Effects

Effects on Birds: No significant effects on other wildlife were reported.
Effects on Aquatic Organisms: The LC50 for rainbow trout exposed to azadirachtin is 0.48 ppm It may cause significant fish kill if large concentrations reach waterways. It breaks down rapidly (in 50-100 hours) in water or light, and is not likely to accumulate or cause long-term effects
Effects on Other Animals (Nontarget species): Azadirachtin is relatively harmless to spiders, butterflies, and insects such as bees that pollinate crops and trees, ladybugs that consume aphids, and wasps that act as parasites on various crop pests. This is because neem products must be ingested to be effective. Thus, insects that feed on plant tissue succumb, while those that feed on nectar or other insects rarely contact significant concentrations of neem products. Another study found that only after repeated spraying of highly concentrated neem products onto plants in flower were worker bees at all affected. Under these extreme conditions, the workers carried contaminated pollen or nectar to the hives and fed it to the brood. Small hives then showed insect-growth-regulating effects; however, medium-sized and large bee populations were unaffected. A study of neem products and their effect on mortality, growth and reproduction of earthworms in soils was conducted. Positive effects on weight and survival were found in soil treated with ground neem leaves and ground seed kernels under greenhouse conditions. Reproduction was slightly favored over a period of 13 weeks in a neem-enriched substrate in rearing cages. Various neem products were incorporated in the upper 10-cm soil layer of tomato plots. None of the materials had negative side effects on seven species of earthworms. No significant effects on other wildlife were reported.

Environmental Fate

Breakdown of Chemical in Soil and Groundwater: Accumulation in the environment is not expected.
Breakdown of Chemical in Surface Water: It breaks down rapidly (in 100 hours) in water or light, and will not cause long-term effects.
Breakdown of Chemical in Vegetation: Azadirachtin is considered non-phytotoxic when used as directed
