Sticky Sap

Posted by John Fulton -

People are beginning to complain about leaking sap coming from trees. Actually this has been going on for a week or so. What happens is a fine mist of sap coats things beneath a tree. This is actually called "honeydew," which is a secretion of sucking insects such as aphids and lace bugs. What makes matters worse is a fungus begins growing in the honeydew, making it turn black....

Fall Defoliators

Posted by John Fulton -

As we enter August, we usually don't think of fall - at least not quite yet. However, a quick trip through Southern Illinois this weekend showed the heat of the season has caused insects to develop faster than usual. The fall webworms are out in force, and they are one of the more visible fall defoliators. Let's begin by listing some of the culprits. Fall webworms, Eastern t...

Grub Control Options

Posted by John Fulton -

Questions are beginning to come in regarding grub control. As a reminder, the date should be early August for annual white grubs. Treatment times for Japanese beetle grubs should probably be late August this year. Knowing when to treat grubs is one thing, and knowing what product to use is another. Many grub control treatments are combined with fertilizer produc...

Anthracnose on maple

Anthracnose and Apple Scab

Posted by John Fulton -

As predicted earlier in the season, fungi have really kicked in on shade trees and ornamentals. Anthracnose is easily seen on good quality maples, and apple scab is rapidly defoliating both crabapples and production apples not in a regular spray program. Both diseases fall into the category of "preventable but not curable," but don't despair. Assuming the trees have enough stored energ...

Foundation Sprays

Posted by John Fulton -

The crickets, millipedes, earwigs, spiders, ants, and many others that find their way inside are a real nuisance. A foundation spray is the best line of defense, and you would select a material such as permethrin or bifenthrin to begin with. Then spray the foundation and the adjacent foot or two of soil or plant material with the spray mixture. Both these products are cleared on most types of p...

Green June Bug

Green June Bugs

Posted by John Fulton -

A large, green beetle which sounds like a bumblebee when it flies, has emerged in the last week. No, it isn't a Japanese beetle on steroids. It is a green June bug. These insects also have a grub stage, but are not usually pests. They tend to lay eggs in high organic matter places such as in flower beds, under shrubs, compost piles, gardens, and manure piles. The adult beetles can cause damage to...

Cicada killer wasp

Cicada Killer Wasp

Posted by John Fulton -

The cicada killer wasps will return shortly. They are actually considered beneficial insects because they control cicadas and katydids. This wasp gets its common name due to the fact that it hunts and supplies its nest chambers with a cicada, which becomes a food source for the young wasp. Cicada killers are a nuisance pest, especially when nesting in large numbers in a play area or near the ho...

Rust on Lawn Grass

Lawn Rust

Posted by John Fulton -

As grass growth slows, rust will be one of the lawn fungi we are dealing with. Rust appears as an orange or yellowish-orange powder (spores) on grass leaf blades, especially in late summer to early fall when the weather is dry. Rust typically develops on lawns growing very slowly. Overall, the turf may assume a yellow, red, or brown appearance. Rust spores can easily be tracked into homes. Othe...
