The pesticides used however needs to be as specific as possible for the target.When the alternative methods are not properly used then the pesticides are used for pest control.IPM doesn’t totally avoid the use of the pesticides.Other non-chemical methods include biological, physical and ecological methods.Use of live natural enemies is one of the major non-chemical (biological) intervention method.Examples of non-chemical methods include soil-solarization or biological control.As chemical methods are often not sustainable and creates more pest problems, non-chemical methods are always preferred at first hand as they are more sustainable with less biological and environmental hazards.Non-chemical methods are prioritized over chemical methods if they can produce satisfactory results.We should also be aware that specific crops, pest life cycle, climatic condition, etc., should be considered before making any kind of decisions.However, threshold is difficult to define in most of the cases and in case of tolerant species, decision of intervention is based on the general observations.Threshold is the defined pest density, or population level, which when exceeded, management should occur. IPM focuses on threshold-based intervention in most of the cases.Decision making is done based on the results of the monitoring.Many countries like France, Denmark have adopted this monitoring and forecasting technique.Monitoring can be done through observations, use of scientifically sound warning, forecasting and early diagnosis systems, advice from professionally qualified advisers, etc.Harmful organisms must be monitored by adequate methods and tools, wherever available.Related Post: Advantages of Intercropping and Crop Rotation Principle 2: Monitoring stale seedbed technique, sowing dates and densities, under-sowing, conservation tillage, pruning and direct sowing) Prevention and suppression also include use of adequate cultivation techniques (e.g.One of the methods of prevention and suppression is crop rotation where it would break the life cycle of the pests.by regular cleansing of machinery and equipment) It is a method of preventing the spreading of harmful organisms by hygiene measures (e.g.Prevention and suppression can be done by applying the different techniques.Suppression is reducing the impact of the pests. Prevention is adoption of measures to reduce the chance of occurrence of pest.Principles of IPM: Integrated pest management Principle 1: Prevention and Suppression This information is then used to manage pest damage. IPM programs use information on the life cycles of pests and their interaction with the environment.IPM incorporates several biological, ecological, physical and chemical strategies for controlling the pests’ problems.Furthermore, IPM can also be considered as a pest control program that combines several methods for prevention from the pest and protection of the plants.It is an eco-friendly method of pest control.It is a method which is used to solve pest problems without or at low level of risk to the people and the environment.Under this method, pesticides are only used according to standard established guidelines and treatment is done with a goal of removing only the target organisms.It is an approach to control the pest in an integrated way.Integrated Pest Management (IPM) is an ecosystem-based strategy that focuses on long-term prevention of pests or their damage through a combination of techniques such as biological control, habitat manipulation, modification of cultural practices, and use of resistant varieties.What is Integrated Pest Management (IPM)? However, the problem still continues and use of pesticides further leads to other gigantic problems.Usually, lots of chemicals or pesticides are used to get rid of them.Pests are usually defined as the insects or other animals that attacks the crops and destroys the cultivation.
