One of the methods for controlling pests is biological pest control and it is used by other organisms. It replies on parasite, herbivore, predation, or other natural mechanism and it is typically involved in the human management role. Ancient biological control involved in natural enemies of the pest that are in the laboratory and released from the environment. In another method, natural enemies occur in small areas by releasing more or small, single large scale release, repeated batches, breed from release organism and to provide long term control. The most important component to integrate pest programmed is biological control. For example- Bacillus were used to control mosquitoes, in local water the bacteria is to infect and kill the mosquito larvae. To expose insect pests to predators are by cultivation such as black-headed gulls.
Mechanical pest control is a simple thing and it is a hands-on technique. Between plants and insects are the protective barrier that provides mechanical pest control. It is one of the ancient methods of weed control and it is very useful for Pest control Southend . For newly plowed grassland, wireworms are a very destructive pest and its repeated cultivation exposes them to birds and also for other predators that feed on them. Crop rotation is used to help to control pests by host plants. It is a major trick to control corn rootworm and it reduced Colorado potato beetle in the early season by as much as 95%. A trap crop is a simple method to crop a plant that will attract pests, it diverts from nearest crops. Pest more aggregate in trap crops that can be controlled easily using pesticides or some other methods. Moreover, trap cropping is failed to cost-effectively and it reduces pest densities on more commercial scales. The pest possibility was dispersed into the main field without the use of pesticides.
These pesticides are applied to all crops with the help of crop sprayers, aerial spray, agriculture aircraft, or seed dressing to reduce pests. It is not easy to control pesticides, it is an easy process only when the right formulation is chosen at a crucial time. And also a method of application is important to adequate coverage and retention of crops is a must. Target pests will be minimized by killing natural enemies. In most of the countries, these are particularly important where they contain a reservoir of pests and enemies in surrounding plantation crops and it coexists in a delicate balance. In developing countries, in the local situation, the crops are well adapted and don’t need pesticides. By using fertilizer to grow various crop varieties, these are more impact in pest damage, but the indiscriminate of pesticides are in long term. Chemical pesticides are diminished over time due to efficiency because any organism that tends to survive the starting application that will pass the genes to offspring and the resistant strain will develop automatically. In this way, only most pesticides have developed the resistance and it is no longer to kill by pesticides that are to kill their ancestors. Chemical with higher concentrations and more frequent application leads to the expensive formulation. Moreover, pesticides are formulated to kill pests, but many effects on mon target species; honey bees are damaged on a particular concern. The date is more important at the time of spray applied to crops.
