ORGANIC THRIPS PEST CONTROL IN OUTDOOR CANNABIS GROWS
Unlike in indoor grow spaces where a cannabis cultivator has the free-hand in controlling and manipulating factors that affect pest populations such as temperature, light, humidity and airflow, outdoor growers are at the mercy of nature when dealing with these environmental conditions. For this reason, pest control for a thrips problem in outdoor cannabis grows may be more of a challenge compared to indoor grows. Luckily, these particular pests don’t invade outdoor cannabis crops as much as indoor grows and greenhouses. Still, outdoor cannabis growers need to keep watch as an infestation can significantly reduce yields if not eliminated early.
Much of my experience on thrips pest control has been with indoor cannabis grows, so I reached out to Nicholas Martin, the driving force behind Pest Control Hacks. Nicolas is professional pest fighter like I am—he is also an entomologist who has worked with several large cannabis growing companies and has dealt with thrips issues more than any other pests in outdoor cannabis grows. Here are his recommendations.
First, verify if you really have thrips in cannabis and not any other type of pests.
Why? Because at first, a thrips problem may resemble two-spotted spider mite damage. To check for both larvae and adult thrips on cannabis, hold a white piece of paper under an area of the plant and tap the plant several times. If the pests are present on the plant, this will dislodge the bugs onto the paper where they can then be seen more easily.>
Use yellow or blue sticky traps to monitor for adults. These same yellow or blue sticky traps will also work well for mass trapping if thrips pest populations are high. Special pheromones for thrips are available and can be used in conjunction with sticky traps.
When it comes to pesticides, recommended formulations should include the active ingredient, Beauveria bassiana. ANT & GARDEN ORGANIC PEST CONTROL also recommends any Spinosad-based pesticide if the use of this ingredient isn’t banned in your state.
Biological control is also another safe and organic option for addressing a thrips problem in cannabis. For the young larval stages of this pest, the predatory mites Amblyseius cucumeris and Amblyseius swirskii can be used. The minute pirate bug, Orius insidious, also works very well for adult thrips. For thrips that pupate in the soil, Stratiolaelaps scimitus (Hypoaspis miles) and Dalotia coriaria (Atheta coriaria) can be introduced to the grow area. Nematodes (Steinernema feltiae) can also be drenched into the soil to help control thrips pupae.
