movement, disrupt the nervous system, cause disruption
of receptors regulating cell function and/or create
physiological changes that result in pest mortality. As
efficacy data are not required to commercialize a 25(b)
product, access to new data can be limited. Reputable
companies, however, do generate quality data to support
their 25(b) products and make this information available
to their customers.
Benefits of using 25(b) products include great safety
profiles due to minimum risk ingredients, little to no
residue, exemption from food tolerance requirement
(no maximum residue limits), fewer personal protective
equipment requirements, no restricted entry interval
(REI) or preharvest intervals, good tank mix partners,
excellent resistance management tools, and high efficacy
against target pests. Disadvantages include possible
crop tolerance, limited residual activity, volatility creating
fragrance, availability due to supply challenges and cost.
Regardless of the oil product chosen, there are
application considerations. It is important to make sure
the plant is dry within two hours after an application.
The longer a plant is wet, the more likely the oil will
start to degrade the waxy cuticle of the leaf and cause
phytotoxicity. Applications should be made when
relative humidity is less than 85%. Additionally, ambient
temperatures should be below 90° F with applications
ideally in the morning or afternoon.
Now that we have all the information on the types of
oils, how do you choose? What is best for your operation
and situation? It doesn't have to be either/or; have both
HMOs and 25(b)s on hand and use them in rotation.
Choose which product(s) to use based on the pest and
the current circumstance. For instance, use HMOs when
you can observe the REI and 25(b) when you need
earlier access to the treated greenhouse, and 25(b)
products can offer the flexibility in treatment timing you
have been missing.
