Veggie Gardening 101: Integrated Pest Management (IPM)

Practices like mulching, using protective netting, and selecting disease resistant plants are called Integrative Pest Management and can help reduce the probability that your garden will suffer from diseases and insects.

If your garden does suffer from diseases or insects there are several options for managing the issues to slow down the spread or save the plant. Gardeners can use organic or conventional treatment options to deal with most issues. Knowing what to use and when to use it can help keep gardens healthy and productive throughout the season.

Chemical measures may be undesired in a home garden, but there are many options available to the home gardener that can be incorporated as part of an integrated approach. Correctly identify whether the signs and symptoms that you are noticing in your plants are the results of an insect or disease.

Pesticides are classified based on whether they kill, repel, or control either insects, weeds, or fungi, and choosing the wrong product will be ineffective and waste time and money. Read the pesticide label before you purchase the product, and make sure the pest and vegetable are listed. The label has instructions on how to mix, apply, and optimally treat for the pests. There are likely multiple products and formulations that may be labeled for what you need, but it’s best to consider using the least toxic, yet most effective options. Least toxic options include insecticidal soap, horticultural oil, botanical products like neem oil, and biological insecticides like bacillius thuringiensis. Many of these products have a zero-day preharvest interval, meaning there are no days to wait between the last application and harvest date. These products require complete coverage to protect the plant and repeat applications, which is the trade-off for using an organic product.

Regardless of whether you choose an organic or conventional product, it is important to reduce exposure to people, children, and pets during and after the application. Protect the environment by preventing the movement of chemicals from the treatment area, as it can damage other plants and kill beneficial insects like bees and other pollinators. It may also have the potential to enter waterways and aquatic habitats, causing harm to fish, birds, and other wildlife.
