Neem Oil is being used worldwide to control pests of standing food crops in fields, tea gardens, stored grains / crop roots and tubers, rice paddy, horticulture fields and green houses.
It is the General Purpose Botanical Pesticide of choice for Organic Agriculture. Neem Oil is widely used in several countries around the world today either singly or in Integrated Pest Managment or in conjunction with synthetic pesticides. Amongst the other known botanical pesticides such as Rotenone and Pyrethrins, Neem Oil is superior due to reasons cited below. Research has shown that neem extracts can influence nearly 200 species of insects. It is significant that some of these pests are resistant to pesticides, or are inherently difficult to control with conventional pesticides (floral thrips, diamond back moth & several leaf miners). Neem Oil belongs to the category of medium to broad spectrum pesticides. It works by intervening at several stages of the life of an insect. It does not kill the pests instantaneously but incapacitates it in several other ways. |

Being anti bacterial and anti fungal, suppresses trichophyton (responsible for athletes food infection) helps keep kitchen garden / lawn naturally free from flies, grasshoppers etc. Highly effective on pets, cows, cattle, sheep and other live stock by making them naturally free from ticks, scabs-mites, blowflies, hornflies, bitingflies (blood sucking fly), mosquitoes etc. |

Mansha’s Neem Oil (Emulsifiable Concentrate) is well suited for an “Integrated Pest Management” (IPM) Program because of the following salient features: |
|
1. Neem Pesticide is a natural product, absolutely non-toxic, 100% biodegradable and environmentally friendly.
2. If required, it can be mixed with other synthetic pesticides ( in fact it enhances their action) .Gradually, the ratio of Neem content in the mixture can be increased and synthetics reduced till you reach a stage where synthetics become redundant.
3. Several synthetic pesticides being single chemical compounds cause easy development of resistant species of pests. Neem consists of several compounds hence development of resistance is impossible.
4. Neem does not destroy natural predators and parasites of pests thereby allowing these natural enemies to keep a check on the pest population.
5. Neem also has a systemic action and seedlings can absorb and accumulate the neem compounds to make the whole plant pest resistant.
6. Neem is harmless to non-target and beneficial organisms like pollinators, honey bees, mammals and other vertebrates.
7. Neem has a broad spectrum of action active on more than 200 species of pests( see list below)

Oil cakes and Oil meals find use as food, feed stuff and as organic nitrogeneous fertilizers. Apart from their contribution to N,P,K, as shown in table below, they have a number of benefits in agriculture, which none of the synthetic fertilizers or pesticides can offer. They bring in the wonderful molecules that nature has designed to help the plants flourish naturally. They provide slow and steady nourishment, stimulation, protection from soil nematodes and insects, improve yields, and quality of product like taste, flavour, amino acid composition etc. |
|
|
These oil cakes are slow in mineralising and hence compliment quicker acting inorganic fertilizers whenever they are applied together. Gaseous Nitrogen losses from oil cakes applied to the plough layer are much smaller than from Nitrate Fertilizers. Some of these oil cakes retard nitrification of the soil/urea and thereby increase Nitrogen uptake by the plants. Phosporous uptake from oil cakes is higher than that from Superphospate in maize plants. |

Oil cakes containing 2 – 7% protien Nirtogen applied at rates 4 – 10% supress soil nimatodes thereby controlling fungal diseases of plants. The above oil cakes in powder or pellet form supress parasitic nematodes, particularly, Meloidogyne Javanica, and those associated with wheat, pulses, potato and betel leaf. They also improve plant health and thereby offer greater resistence to infection.
Also, combination of two or more oil cakes result in synergic effect and help in soil reclamation and revive the natural properties of the soil.
