Most of the rice and corn fields are infested with Flies Infestation and several herbicides and insecticides are used to exterminate the Flies Infestation in the fields. Mostly, the paddy and corn fields are the most infested with Flies Infestation and about 5 years back in Australia, the corn fields had experienced severe Flies Infestation in the form of grass hoppers which had hit the entire world like a storm and in all TV news channels, this was the hot story about Flies Infestation and the Australians used helicopters to spray the insecticide to exterminate the grass hoppers. In the Asian crop fields, the most common form of Flies Infestation will be from the worms and SPIC DAP and Urea are used as insecticides to exterminate the insects. Flies Infestation is a major problem in many crop fields and the farmers have to extreme care in spraying the insecticides on the crops to prevent from getting infected but there are insects that can benefit the crop growth and these also get killed by the insecticides sprayed. Grass hoppers create big menace in the corn fields and eat the flakes and most of the corn gets damaged because of Flies Infestation and the farmers incur heavy losses because of this problem. Government gives loans and subsidies to the farmers to cultivate their lands and do agriculture but these entire amount go wasted as a result of the Flies Infestation and the insecticides are available free of cost to the farmers to protect their crops. There is no doubt that the agricultural yield is very much affected and will be reduced as a result of the Flies Infestation. In order to protect the crops from the Flies Infestation, farmers use harmful insecticides and pesticides on the crops and these are very harmful when consumed by the humans and hence care must be taken in washing all the crops cleanly to remove the strains of these harmful insecticides in the crops that are used against Flies Infestation. The food gets poisoned resulting in dysentery and various other problems for the humans due to this treatment against Flies Infestation and the farmers are advised to use the insect and fly killers minimally to avoid the problem of crops getting over exposed to the harmful chemicals spoiling the nutrients and the natural characteristics of the crop and is a sign of artificial chemicals dominating the nature obviously resulting in adverse effects.
