CHEMICAL UPDATE: FERTILIZER/PESTICIDE COMBINATIONS
As an extension of our
Turfgrass Chemical Updates, Grounds Maintenance publishes additional
Chemical Updates throughout the year. Extensive information about chemical
characteristics and pests controlled is found in the first three Updates,
published in January, February and March. However, these Updates cover only
straight chemical products. Therefore, to provide a reference for those of you
who rely on combination products, we’ve compiled a listing of
pesticide/fertilizer combinations.
Unlike our previous
updates, these tables do not cross reference chemicals with pests controlled or
other information, which can be found in prior Updates. These lists provide an
overview of available products, including fertilizer analysis, percent active
ingredient and available brands. “Various” under fertilizer analysis means the
supplier formulates the active ingredient with numerous fertilizer analyses, or
custom blends the combination.
An obvious advantage of
combination products is that you can fertilize and control pests with a single
application. This is a great labor saver, but it requires you to carefully
formulate your management strategy. Combination products require appropriate
timing for both the fertilizer and the chemical.
Because the rates of
the fertilizer and the pesticide are linked, you sacrifice some flexibility.
For example, you could not put the product down a little heavier for some extra
fertility, because doing so would probably violate the label instructions.
However, when timing and rates mesh properly, there’s no way to beat the
economy of one granular application to make two treatments.
The fertilizer
component of combination products varies widely. It may include fast- or
slow-release fertilizers (usually some of both) and the analyses cover the
entire fertilizer spectrum. For more specific information about the fertilizer
content of a product, you must consult with the supplier.
Pre-emergence herbicides dominate the available combination products. This makes sense, because turf managers typically apply pre-emergents at about the same time as fertilizers (in spring, for example) and in a similar manner (by spreader). That’s why most major pre-emergents are available in combination with fertilizers.
Post-emergence
herbicides also are available with fertilizers. These, of course, are the
popular “weed-and-feed” products that have been around for many years. Though
perhaps more popular in the retail market, these products also are available to
commercial operators.
Insecticides comprise a
much smaller number of combination products. However, if you’re looking for
grub controls, you’ll find no shortage of options. Dursban, a staple product
for many pest-control programs, also is available. Finally, though relatively
few in number, several valuable fungicides are available in combination with
fertilizer.
When you use combination products, don’t forget that you are working with pesticides, and you must follow all label instructions. This listing is not a recommendation or substitute for application instructions. If you would like more information about a product, you can contact the supplier via the information in the box below. They will provide you with additional information, including labels, and help you locate a distributor near you.
