Adjuvant Helps Lock Out Insect Pressure

Darrin Holder
Agronomist, WinField
Summer brings a range of damaging insects to corn, soybeans, cotton, grain sorghum and many other crops in your fields, making diligent scouting critical. Controlling insects as soon as possible will help put them out of commission before they’ve achieved multiple lifecycles and larger populations, and before your plants reach the critical reproductive stages. This could have a positive effect on yield potential. 

Applying the appropriate insecticide can help minimize crop damage and yield loss. But don’t forget that adding an adjuvant can help increase the effectiveness of your insecticide applications.

Technologies that double-team insects
MasterLock® adjuvant by WinField United combines InterLock® and DropTight™ technologies in one crop-based adjuvant to enhance spray coverage. InterLock® adjuvant, contained in the mix, helps ensure that droplets are the right size, which reduces the amount of fine particles in the spray pattern and helps drive droplets deeper into the canopy for better deposition.

DropTight™ technology, unique to MasterLock® adjuvant, helps droplets stick to the target: the plant you are trying to protect. Together, these technologies give you a one-plus-one-equals-three benefit. They enable deposition to help insecticides stay on target, reach the pest and optimize performance.

Get pests where they live
In the heat of the day when the majority of insecticide applications are made, MasterLock® adjuvant is effective at getting deep into the crop canopy where insects are thriving — and feeding — in cooler temperatures and more humid conditions than on the surface of the crop. Be sure to determine insect pressure through not only observing the top of the crop, but also by working with your agronomist to do sweeps into the canopy. Doing both will help you get a more complete picture of your insect population and if the economic threshold that justifies an insecticide application is being met.

Ascertain the economic threshold
Work with your agronomist to determine the optimal time to do an insecticide application. Make sure you are working with the most current commodity price information to determine when you’ve reached the appropriate economic threshold for each species of pest and each type of crop. Sources for this information include your agronomist, as well as local universities and extension offices.

Make sure equipment is ready
When application timing is determined, be sure to achieve optimal product performance by working with your agronomist to select the right boom height, as well as the right nozzle type, size and pressure — so you can adjust your own sprayer or inform your applicator about these specifications.

Northern States Win the Planting Race

Agronomy Team
Mother Nature blessed much of northern Illinois, Iowa, Minnesota, South Dakota and Wisconsin with favorable planting conditions this season, helping many farmers complete corn and soybean planting on or before average planting dates.
Meanwhile, some farmers in southern Illinois, Indiana, Michigan and Ohio and are still racing to complete planting due to cool, wet weather, which delayed planting progress. Spotty frosts throughout most of the Midwest have caused concern for early crop damage, but no widespread replanting has been reported.
The Triple Threat – Diseases, Pests and Weeds
In states with fluctuating temperatures and consistent wet conditions, farmers should be scouting for seedling diseases in corn and soybeans, especially in areas that experienced extended cool, wet soils and delayed emergence. Reports have already surfaced in Indiana about some cornfield replants due to disease-induced stand reduction. In Iowa, farmers are advised to scout cornfields for diseases such as anthracnose during V4 and V5.
Wet weather has also been conducive to insect development, including slugs, which have been reported in some Ohio fields. In Wisconsin, black cutworm larvae have recently been spotted and can be treated with an insecticide tank mixed with herbicide applications.
Weeds continue to be top of mind for all farmers, but especially in fields that did not receive a burndown or preemergence herbicide application. Farmers are encouraged to scout fields regularly and treat weeds when they are between 2 and 4 inches tall for easier control.
