Mites can be some of the most destructive pests in a vineyard. When it comes to achieving effective control, it all starts with coverage.
Dr. Darin Allred, Technical Sales Support Representative for Arysta LifeScience, advises growers to not only select the right crop protection product but also focus on the best IPM practices in their vineyard. And that includes getting the best coverage with miticide applications when pest populations reach the treatment threshold level.
“Since mites populate underneath the leaves, they’re often shielded from the sprays,” he says.
Allred adds that applying miticides before the canopy gets too dense is one way to get around this.
“Nothing can replace being proactive by diligently scouting the crop, determining your treatment threshold level and getting in early with your miticide treatment before a spider mite population explodes,” Allred adds.
Early sprays are key, and getting the timing right – early rather than later – is critical. Lowering the speed of the sprayer will help ensure better coverage – 2 mph is ideal. This will help reduce inadequate coverage resulting from the “leaf flagging” issue often experienced in spraying grapes, where the leaves are blown parallel to the miticide spray stream, like a flag in the wind, which can reduce the amount of product adhering to the bottom surfaces of the leaves. Also, pay special attention to applying selective miticides to maintain populations of beneficial insects and predator mites which will help control spider mites later in the season.
“It’s always difficult to predict mites in any given year,” Allred says. “A good predictor will be what insecticides growers are using early in the season to control other insects, such as grape vine mealybug, and how those treatments are affecting the predator mites, sixspotted thrips and other predators of spider mites.”
For miticide applications, maintaining good IPM practices and the populations of beneficials is important. Arysta LifeScience provides miticides with the flexibility that growers need, with quick knockdown, long-lasting control, and selectivity on beneficial insects and predator mites, for excellent IPM compatibility.
VIGILANT® and ACRAMITE® Miticides provide the flexibility of controlling spider mites at all life stages while going easy on beneficial insects and predator mites. And since resistance management is a critical part of any IPM program, KANEMITE® Miticide offers a unique chemical subgroup for fast knockdown of all stages of spider mites while also being easy on beneficial insects and predator mites.
