Guarding against resistance!

Learning Objective:

Participants should be able to understand managing resistance is critical and what their role is in supporting best practice

Pesticide resistance is a natural evolutionary process in which pests become less susceptible to the effects of pesticides over time. This happens when individuals with genetic traits that allow them to survive exposure to a pesticide reproduce and pass those traits on to their offspring, leading to a build-up of resistant individuals in the population.

Managing pesticide resistance is important for several reasons:

  • It helps to preserve the effectiveness of existing pesticides. When resistance develops, the same pesticide may no longer be effective against the target pest, which can result in increased use of pesticides, higher costs for farmers, and negative impacts on the environment and human health.

  • It can delay the onset of resistance, allowing for longer-term and more sustainable use of pesticides. This can be achieved through strategies such as rotating the use of different pesticides, using multiple modes of action, and reducing overall pesticide use.

  • It can help to prevent the spread of resistance to other regions or countries. When resistant pests are transported from one area to another, they can spread resistance traits to local populations, making control more difficult and costly.

  • It can support integrated pest management (IPM) approaches, which rely on a combination of methods, including biological control, cultural practices, and chemical control, to manage pests sustainably.

In summary, managing pesticide resistance is crucial to preserving the effectiveness of pesticides, promoting sustainable agriculture practices, and protecting the environment and human health.
