The interference and damage result in the failure of plants to reach their genetic potential. As a consequence, it is estimated that pre- and postharvest pests and diseases destroy at least 30–40% of global agricultural production. Cultural controls are one of the most common and effective ways to control pests and diseases in the garden. This involves using practices such as crop rotation, mulching, and companion planting to create an unfavorable environment for pests and diseases. Four common methods are used to control pests and diseases. They are: biological, cultural, chemical and integrated control. Biological control is the use of useful and beneficial living organisms, such as predators or parasites, to control pests. Predator insects feed on the pests and can control their numbers.

The best ways to protect crop damage are by incorporating integrated pest and insect management. Spraying insecticides, pesticides help to minimize the crop damage by controlling the insects and other pests. Among the crop protection techniques are tillage, crop rotation, organic and synthetic pesticide use, field monitoring, etc. Introducing efficient farming methods requires growers' appropriate plant protection strategy. A variety of chemicals are available that have been designed to control plant diseases by inhibiting the growth of or by killing the disease-causing pathogens. Chemicals used to control bacteria, fungi and nematodes may be applied to seeds, foliage, flowers, fruit, or soil. The insect pest cause on an average 15 –20% yield losses in food and cash crops. Due to heavy of Insecticides use in agricultural field, the natural biocontrol agent's numbers are drastically declined.

In the absence of crop protection, yield losses of up to 70% can occur across many major food crops, with weeds accounting for the highest losses at 30%, followed by animal pests and pathogens at 23% and 17%, respectively. On average, pests account for 20-40% of yield losses worldwide, costing the global economy a combined $290 billion, according to the FAO.

Among the crop protection techniques are tillage, crop rotation, organic and synthetic pesticide use, field monitoring, etc. Introducing efficient farming methods requires growers' appropriate plant protection strategy and training. For example, they must know how to process seeds and prepare fields for planting.

In agriculture, plowing and tillage of the soil might be used to control weeds and traps are also used for monitoring insects and catching pests. Biological controls are natural enemies of the pests, such as animals and other creatures. Among the crop protection techniques are tillage, crop rotation, organic and synthetic pesticide use, field monitoring, etc. Introducing efficient farming methods requires growers' appropriate plant protection strategy and training. For example, they must know how to process seeds and prepare fields for planting. Chemical pesticides are often used to control diseases, pests or weeds. Chemical control is based on substances that are toxic to the pests involved. When chemical pesticides are applied to protect plants from pests, diseases or overgrowth by weeds, we speak of plant protection products. The loss of agricultural productivity of crops due to insect pests was estimated to be 15.7% and a valuable tool for crop protection or pest management has been based on the biological control of pests via microbial pathogens, such as bacteria, nematodes, viruses, and fungi. Insects with chewing mouthparts, for example, grasshoppers, caterpillars, and beetles, cause feeding damage such as holes or notches in foliage and other plant parts, leaf skeletonizing leaf defoliation, cutting plants off at the soil surface, or consumption of roots.
