SO YOU THINK YOU HAVE A PEST PROBLEM?
The proper identification of insect pests, their life cycles and how their mouthparts damage plants are critical for successful management using both biocontrols and chemical insecticides. Many biocontrols are host specific, meaning that they attack only certain insect pests. Many biocontrols are only sucessful by managing certain stages of  the insect's life cycle at certain stages of their own life cycle. The same is true for insecticides where on the label it will tell you what life cycle stage the chemical is the most effective at managing that particular pest. Identifying what insect damage looks like on plants is essential for knowing that a pest infestation is on the rise. Knowing which crops your growing that are susceptible to certain pests (and diseases) is also a key component for sucessful pest management so they can be routinely scouted for infestations. Below you will find a variety of common greenhouse pests and their biological control agents with information on their life cycles.

FREE BIOLOGICAL CONTROL !!!

Not all insects that venture onto your crops are the bad guys. There are many naturally occurring biological control agents that work just as well if not better than commercial brands. Click here to learn more about free biological controls!

PLANT-MEDIATED IPM SYSTEMS

Plant-mediated IPM systems use plants in combination with other suppression tactics to manage arthropod pests. They offer a cost-effective, innovative approach to sustainably managing pests in protected environments. These systems are developed to:

1) Improve early pest detection (indicator or sentinel plants);

2) Attract pests off the crop where they’re targeted for management with bio- control, chemical insecticides or by removing and destroying them (trap crop), or

3) Provide habitat, food and shelter for biological control agents (habitat, insectary/banker or guardian plants).

PESTICIDE COMPATIBILITY 

If pesticides must be applied due to unanticipated disease or pest problems it is important to choose the ones that are the most compatible with your biological controls. Pesticides are the most harmful to biological control through direct contact, but the residuals also make it difficult for them to find prey by interfering with their behavior. The Koppert Side Effects List , Biobest Side Effects Manual and Syngenta Compatibility Chart provide the most up to date compatibilities of pesticides with biological controls. Biobest also offers a smartphone app available for Apple, Android & Blackberry. All you need to know is the name of the biological control and the pesticide active ingredient. We have also compiled lists of pesticide-biological control compatibilities. List A , List B 2005, last updated 2013. Always remember though, your best source of up to date information is directly from your biological control supplier!!
