Insect Create Great Loss to Crops

In developing countries, damage by agricultural crops by pests can cause economic loss and starvation to farmers. As a precaution, it is harmful to human health, and as many customers do not want to eat it, farmers use a variety of insecticides to kill insects. Also, in the case of heavy rain, chemical pesticides may flow into the water supply system and lead to an unsanitary environment. An example of elimination of pesticide use in the market and reduction of crop cost is the corn Bacillus thuringiensis (B. t) gene.

Viral diseases of plants often destroy the whole crop. Most plant viruses diffuse by biting insects and sucking. Traditionally, farmers sprayed wide area pesticides to reduce crop losses. There is a better way. Scientists have developed a way to immunize crops against viral diseases. It is called interfering RNA or RNAi. As with animal vaccines, placing a small portion of the viral genes (in RNA form) in plants protects against virus attacks. The first antiviral transgenic crop is papaya

Plant virus causes serious yield and quality degradation in most crops. Loss is 5 to 90%. Loss of large amounts of crops occurs due to attack by pests and microbial pathogens. Little is known about how to obtain the genetic mechanism of plant disease resistance. Genetic engineering is expected to greatly affect crop breed improvement. It has been suggested to develop new genes for disease resistance and expand the use of existing disease resistance genes using genetic engineering techniques. Genetic transformation can promote plant breeding efforts to develop disease resistant varieties. Cloning of plant genes responsible for pest resistance is useful for elucidating several biological mechanisms of resistance

Planting insect-resistant and herbicide tolerant crops allows farmers to grow with less growth. More than a third of the world's potential crops such as weeds, insects, diseases are cut down every year. Biotechnologies such as genetically modified soybeans and genetically modified cotton and genetically modified crops help farmers reduce the loss of pest production and cultivate more food without increasing land production. Pest-resistant Bt crops provide targeted pest control that allows breeding of unimportant insects such as bees, butterflies, crickets, ladybugs and so on. In addition, herbicide-tolerant crops help farmers reduce the use of pesticides to protect beneficial organisms. Improving water management with drought and herbicide tolerant crops can protect dependent resources and ecosystems that depend on it
