A pest is any organism that spreads disease, causes destruction or is otherwise a nuisance. Some examples of pests are mosquitoes, rodents, and weeds. Not all insects are pests. Many different kinds of insects eat other insects and are beneficial species.
What do you mean by pest control?
Pest control, a process that maintains nuisance organisms below economic thresholds, is a complex ecological process often mediated by biodiversity. Agricultural intensification results in widespread losses of biodiversity, with important implications for pest control.
What is agricultural pest management?
U.S. farmers employ a range of pest management strategies to control weeds, insects, fungi, viruses, and bacteria. They till their soils, rotate their crops, scout their fields, and carefully consider factors such as plant density and planting dates. They also apply organic and synthetic pesticides.
What is the importance of pest and diseases?
Pest management is an important component of crop production. Pests can have a detrimental effect on horticultural operations by affecting the quantity, quality and ultimately, the marketability, of the crops grown. A pest is any animal, insect, weed or disease that attacks a crop.
How pest and diseases affect agricultural production?
Plant pests and pathogens interfere with the growth and cause damage to cultivated and naturally growing plants. The interference and damage result in the failure of plants to reach their genetic potential.
Why is pest control important in agriculture?
Without crop protection, including pesticides, more than half of the world’s crops would be lost to insects, diseases and weeds. Pesticides are important. They help farmers grow more food on less land by protecting crops from pests, diseases and weeds as well as raising productivity per hectare.
What is the importance of pest control?
Pest control is necessary because rodents and insects carry diseases, infest your kitchens and bedrooms, and bite you or your pets. The purpose of removing any kind of pest from your home, garage, or yard is to keep you safe and healthy. For example, rodents can leave feces on or near food they find in your kitchen.

Examples. Vertebrate Pests. Deer, raccoons, rabbits, birds, and other creatures can eat the corn crop at various stages of the growth of the corn. Invertebrate Pests. Cutworms are the larvae of what will eventually become a moth. In the larvae stage, the cutworms live near or below the soil surface.
What do cutworms eat?
In the larvae stage, the cutworms live near or below the soil surface. The cutworms feed on corn that has recently emerged from the ground, chewing off the small corn sprouts causing damage that often appears as if the corn has been “cut.”. Other invertebrate pests can attack corn at various stages of growth. Weeds.

How to control fungus on a tree?
The tender leaves of the tree during winter are more susceptible to the infection. Spreading the compost under the trees and preventing splash dispersal of the fungus is effective to control the disease. Irrigating the plant in the morning or early hours helps the leaves to dry, so that infection occurrence is lower.
What are the external conditions that cause diseases to grow?
While diseases grow within the plant, the external conditions like rain, wind, water, soil facilitate the spread of the disease to the neighbouring plant. Seasons and weather conditions are also responsible for the growth and spread of diseases in plants.

How do pests affect agriculture?
Pests are organisms that interfere with the yield of agricultural ventures in crop production or rearing of animals. They affect a farm’s productivity, which is why farmers over the years have come up with different methods of combating or controlling it. Pests are significantly harmful to man and his source of survival.
How to get rid of pests in a dirty environment?
Maintaining a clean environment – Most pests thrive in a dirty environment, so the best to get rid of them is to make it impossible for them to breed. Inter-cropping – This is a practice where different crops are planted on a piece of land. By inter-cropping, it will be difficult for the pest to survive.
How to get rid of macro pests?
Handpicking – this is practically picking and getting rid of pests. Setting Traps – this is most effective for macro pests. Building fences – to prevent the unwanted presence of the macro pest. Creating Scarecrows – setting up scarecrows will help prevents birds from eating up the crop.
What is the scale of agricultural production?
The scale of agricultural production. The effect on the product. For instance, if you are to use pesticides to control larvae pests in crops, you’ll need to take into consideration the effect of the chemical on the crop that will be consumed eventually. Pests can be divided into two main categories; Micro and Macro Pest.
Why is intercropping important?
By inter-cropping, it will be difficult for the pest to survive. Crop Spacing – When the crops are properly spaced, it will prevent the pests (especially micro pests) from traveling from one crop to the other. Cultural Pest Control is another natural and ecofriendly way of controlling the pest.
Why is macro pest control important?
On the other hand, MACRO PESTS are bigger; they also can cause monumental damage to agricultural produce. This is the reason why a pest control method must be adopted to eradicate pests or reduce their population to the barest minimum.
Why are organic pesticides added to soil?
Organic pesticides are added to soil or other environmental compartments deliberately to control pests and disease in agriculture. The increased sorption and decreased dissipation of pesticides in the presence of biochar may lower the risk of environmental contamination and human exposure from the perspective of ecosystem and human health. Furthermore, the decreased bioavailability and plant uptake may increase crop yield and reduce organic pesticide residues in agricultural crops. However, since a pesticide that is intended to control specific pests or weeds needs to be bioavailable to be effective, the decreased efficacy of organic pesticides because of application of biochar is undesirable ( Mesa and Spokas, 2011; Kookana et al., 2011 ).
What did the spread of animal manures in the field do to the soil?
Spreading animal manures in the field, as well as inclusion of leguminous crops, helped to add nitrogen, a principal nutrient, to the soil .
What are some alternatives to agrichemicals?
Pressure for sustainable practices, both through markets and regulatory bodies, and the increasing problem of pesticide resistance are pushing the industry to find alternatives to agrichemicals. Currently, such alternatives include plant-derived essential oils, plant defense stimulants, biopesticides, and conservation biological control techniques. At this time, conservation biological control and biopesticides are being used in narrow niches of agriculture and are generally effective with an understanding of the system and its limitations. Research is now underway to make both these techniques more effective under a wider range of environmental conditions, pest species, and cropping systems.
What is the role of algae in rice farming?
In the rice farming areas of Asia, the occurrence of blue-green algae (cyanobacteria) in the flooded rice paddies similarly helped to supply nitrogen to the soil, and the application of organic residues, including human wastes, further helped to maintain soil fertility.
How does soil contamination affect floods?
Soil contaminants can negatively impact flood regulation, if the vegetation growing on the affected area is hampered. However, in other cases, soil contaminations might have a positive feedback on the regulation of flood events (e.g., vegetation growth can be stimulated by N deposition).
What are the services that are needed for biodiversity?
There is now growing evidence that biodiversity conservation and critical ecosystem services, such as pollination, pest and disease control, decontamination, water infiltration, and supply to plants, need to be delivered at landscape scale. There is consequently a need to improve the design of landscapes for enhanced function through such means as biodiversity corridors and the creation of more natural ecosystems within which natural resource capital, such as trees and conserved water bodies, meets the needs of humanity and the environment. Further natural principles to be included are recycling and composting of organic waste using vermiculture and related techniques.
Do insecticides affect nontarget organisms?
This is the case of agricultural insecticides. While they are design to control specific pests, insecticides also affect nontarget organisms . This brings a specific concern on soil food webs and on the interspecific relations that control pest dissemination.
