FIELD OF INVENTION
The invention relates to an insecticidal combination for effective control of insects.

BACKGROUND OF THE INVENTION
In recent times the trend of growing resistance to all kinds of Insecticides, formation of residues are great concern and utmost challenge to the scientist community as a whole. With rapid urbanization there is a constant erosion of farming land and at the same time increasing population has created a growing demand of farm products resulted increasing trend of intensive cultivations of crops which favours numerous disease attack on crop plant.

The diversity of insects and their potential for causing serious loss of crop yield in combination or singly has resulted in the need for broad-spectrum insect control. There are numerous chemical compounds (insecticides), which aid in preventing insects of crop plants, however most of them have practical deficiencies, which restricts their application. The inability of any one insecticide to control all of the potentially serious insects on one-crop makes the use of combinations or mixtures of insecticides a part of normal control practice. Further, continuous uses of insecticide, which has one way mode of action, always lead the resistance (development in target insects. There.is one of the many sufferings of the prior art.

OBJECTS OF INVENTION
The main object is to use a combination or mixture of insecticide which has a different mode of action on target insect and can prevent resistance development in harmful pests.

The main objective of the invention is to provide a broad spectrum insecticidal composition. Another objective of the present invention is to provide a synergistic insecticide combination, the bio-efficacy of which is superior to the mixture of the individual formulations at reduced rate of application of individual active in combination which will prevent accumulations of residue in plant and its harvests.

Another objective of the present invention is to provide an improved, stable and ready to use insecticidal composition effective against a wide spectrum of insects such as multiple species of thrips, corn rootworms, wireworms, phyto-phagous mites, their eggs & larvae (particularly Panonychus, Tetranvchus and Eotetranvch_u_s_ spp.). termites, boll weevils, cotton bugs, DiamondBag Moth, Colorado beetle, stem borer, leaf miners, plant hoppers, leaf roller in dates, strawberries, corn, rice, cabbage, chilli, sugarcane, cotton Citrus fruits and vegetables etc.

Another objective of the present inventions is to prevent resistant development in insects, more particularly in crop like dates, strawberries rice, cabbage, chilli, sugarcane, cotton, corn, vegetables and fruits. Yet another objective of the present invention is to provide an insecticidal composition which is non-phytotoxic and results in high yield of various economically important crops such as dates, strawberries rice, cabbage, chilli, sugarcane, cotton, corn, vegetables and fruits.

Still further objective of the present invention is to provide an insecticidal composition in a Suspension Concentrate (SC) form.
.
Still further objective of the present invention is to provide an insecticidal composition containing lower concentration of a phenylpyrazole derivative insecticide as compared to tbe known insecticide formulations containing individual ingredients
.
Still further objective of the present invention is to provide an insecticidal composition containing lower concentration of a thiazolidinone derivative insecticide as compared to the known insecticide formulations containing individual ingredients.

Still further objective of the present invention is to provide better plant growth and yield by using eco-friendly formulations.

Still further objective of the present invention is to provide an insecticidal composition of Hexithiazox to overcome the problems faced by the farmers of physically mixing the individual, commercially available formulations at the field.

Still further objective of the invention to load less actives and more efficacy in a single formulation. Still further objective is to check out the physical compatibility of the actives. Still further objective is to check out the chemical compatibility of the actives.

Still further objective is to select the type of formulation for such a combination of actives for optimum result and process development. Still further objective is to develop the stable recipe of the actives using water despite of solvents. Still further objective is to combine actives of two mode of actions. Still further objective is to minimize the chances of resistance develop in crop pests.

SUMMARY OF INVENTION
One possibility for overcoming such difficulties is to alternate the active compounds used, so that the development of resistance can be prevented or atleast slowed down. However, this requires the continual development of new active compounds, so as to avoid selection to the particular mechanism of action.

In contrast, it is more sensible to be able to employ combination which has proven sufficiently effective and able to control multiple insects for as long as possible, especially when it has shown itself to be environmentally compatible to a particularly high degree and to possess only minimal side-effects.

The present invention relates to novel crop-protecting active ingredients mixture having synergistically enhanced action, comprising atleast two active ingredients component together with a suitable carrier, wherein component I is Hexithiazox, a thiazolidinone compound as active ingredient is known insecticidal compound and have been found to be effective against many insects in dates, strawberries rice, cabbage, chilli, sugarcane, cotton etc. Also shows control of eggs and larvae of many phytophagous mites (particularly Panonychus, Tetranychus and Eotetranychus spp.) on fruit, citrus, vegetables, vines and cotton. The activity of this compound is good; however, it is sometimes unsatisfactory a low application rates and take care of selective insects only. The preparation of this compound is likewise known.

Fipronil, a phenylpyrazolecompound as active ingredient is known insecticidal compound and have been found to be effective against broad range of insects like multiple species of Thrips on a broad range of crops by foliar, soil or seed treatment, Corn rootworms, Wireworms and Termites by soil treatment in maize, boll weevils and plant bugs on cotton, Diamond-back moths on crucifers, and Colorado beetle on potatoes, by foliar application, Stem borers, Leaf miners, Plant hoppers, leaf folders/rollers and Weevils in riee. The activity of this compound is good at Higher application dose which some time led the accumulation of residue resulted harmful for human consumptions; however, at lower application dose, it is sometimes unsatisfactory to control the infestation and only take care few insects.
Some of the insecticidal compositions containing phenylpyrazole derivatives are disclosed in the prior art.Though the combinations in prior arts are effective, there is still a need to find an effective and synergistic insecticide to control many insects in a wide range of field crops, with reduced rate-of individual active in combination.

Efficacy of the combination formulations in present invention are depends upon the use Bf proper quantities of ingredients of individual aetive. There are practical pfobBTris in dispensing exact quantities of the individual insecticidal formulation as tank mix by the farmer in the field. Use of the higher quantities of the individual insecticide then recommended dose can result in phyto-toxicity, accumulation of residue in plant as well as lead wastage and hence higher cost. There are also possibilities of using insecticide with lower dose than recommended dosage, which can fead to fast resistance, incomplete insect control and crop yield loss.

Therefore, considering the importance of effective control of a wide spectrum of insects such as multiple species of thrips, corn rootworms, wireworms, phyto-phagous mites, their eggs & larvae (particularly Panonvchus. Tetranvchus and Eotetranvchus spp.), termites, boll weevils, cotton bugs, Diamond Bag Moth, Colorado beetle, stem borer, leaf miners, plant hoppers, leaf roller in dates, strawberries, corn, rice, cabbage, chilli, sugarcane, cotton Citrus fruits and vegetables etc., simultaneously need for a insecticidal composition which is stable, synergistic, broad spectrum, eco-friendly, ready to use and less expensivewas felt.
