Providing Two-Spotted Spider Mite Repellent for Greenhouse Crops
As spider mites develop resistance to an increasing number of pesticides, the need for new products is a pressing concern for growers. For Kemin, the answer lies in the plants themselves, more specifically, in the rosemary plant.
It’s been known for centuries that rosemary oil has insecticidal properties, and it has been used with varied results for controlling spider mites. The active ingredient in rosemary oil targets octopamine receptors in insects, disrupting their nervous system. All Rosemary is not the same, however, and the amount of the active molecules will differ depending on variety, soil, climate and other factors. But Kemin has refined the growing, extraction and formulation processes to obtain oil with a consistent and effective chemical profile.
TetraCURB is derived from oil produced by more than 1,200 acres of proprietary rosemary plants. The importance of this is the rosemary essential oil will be the same every time. We can assure the consistency and performance of our product because of all the research we’ve done on rosemary – and not just with two-spotted spider mites. We know rosemary very well, because of we have used it for years in our food, pet and personal care divisions. The rosemary oil in TetraCURB is tested with gas chromatography to identify the chemical profile of each batch, and if it doesn’t meet specifications, the oil is rejected.
A Safe, Botanically-Based Spider Mite Control Solution
Spider mites are a major pest on many ornamental crops, from azalea to zinnia, and the yellow speckling (stippling) they cause by feeding on the foliage lasts for weeks even after the mites are controlled. Preventing that damage before it occurs is key. Numerous real-world efficacy trials show TetraCURB reduces mite populations by more than 90 percent, without harming plants. TetraCURB has multiple modes of action, which is why it is effective and why it fits so well into an IPM program. The active ingredient (50% in the concentrate) in TetraCURB targets octopamine receptors in mites – receptors humans and animals do not have. TetraCURB offers a number of advantages, including a zero reentry interval (REI) and for those selling edible plants, a zero pre-harvest interval (PHI), meaning there’s no downtime after application. Rosemary oil is exempt from tolerances, so residue levels are not a concern.
TetraCURB kills mites on contact and volatilizes quickly. You can spray and still work with your plants, either harvesting, shipping or watering. But unlike many synthetic chemistries, TetraCURB contains one active that provides multiple modes of action. The combination of the different modes of action results in weakened mites, therefore, not allowing them to metabolize the active and survive. As a result, growers will experience increased efficacy and reduce the likelihood of developing resistance.
Rosemary oil is made up of a complex set of molecules, and the synergy between them works better against mites than one of them does alone. The oil is also a suffocant, and emulsifiers and wetting agents, which can act as desiccants, are part of the formulation. There also is some repellent activity for one or two days after application.
What Sets TetraCURB Concentrate Apart from the Rest
For growers who lay out their spray programs by IRAC code, TetraCURB, because of its unique modes of action, offers an additional tool in managing resistance and extending the use of synthetic chemistries.
TetraCURB can be sprayed at any time during the season, but we recommend using it at the beginning of the crop cycle. Spray five to seven days apart, typically two times in a row, and switch to another mode of action. The first time kills the current population, along with its egg-laying capability, and the second application kills any mites that hatch afterward. To follow good resistance management practices use two – a maximum of three – times in a row and then switch to another mode of action. After that chemical is used according to its label, you can use TetraCURB again.
