Mosquitos Appearing Soon

The recent bout of heavy but very needed rain will likely trigger a significant increase in mosquito activity in about 10-14 days. In residential areas in particular, now is the time for homeowners to take the initiative to reduce the likelihood of serious mosquito problems around your property before they become reality. Before resorting to insecticide applications, consider a few other critical tasks:

Standing water is the critical item because mosquitoes will not be able breed without it. Permanent bodies of water can pose a more formidable impediment but most of our problems in residential areas are the result of MMOs or "Man-Made Objects" (yes... we guys will take the blame).

Natural low-lying areas will begin to dry slowly but make sure you're not contributing to the problem with clogged drainage ditches, tire ruts, etc.

Other water-collecting items such as empty buckets, tires, dishes under outdoor potted plants, the tarps over boats, equipment, etc. need to be emptied, inverted, discarded or whatever is workable to remove the water.

Have birdbaths? They make great observation posts for watching mosquito larvae in the water. There's no need to add chemicals. Do yourself and the birds a favor and flush out the birdbath. Same thing applies to pet water bowls outdoors (livestock water troughs out in pastures are another issue since they're not always as easily flushed out or routinely maintained).

Excuse time is over - get out the ladder and climb up there and unclog those rain gutters. The decaying leaf material and other debris actually attract mosquitoes. If you're planning home improvements, consider gutter guards to divert the debris. Also, make sure that your downspouts direct the water away from the house and not simply create a big puddle along the side of the house. If you have those concrete or plastic splash blocks, make sure they're directing water *away* from the foundation.

Finally, if you're using rain barrels to collect that precious rain runoff, make sure you have them screened, which helps keep out the junk and the mosquitoes as well.

And while you're at it, get your neighbors to do the same. Mosquito control "takes a village" but it only takes one village idiot to make life miserable for the rest of the neighborhood.

Question: How Do Make a Plant Pathologist's Day?

Answer: Bring in a sample of the spore horns (or telial horns) of the Cedar Apple Rust pathogen. This sample was brought in today from a Henderson County homeowner.

The fungus that causes the disease, Gymnosporangium juniperi-virginianae, is unusual because it must spend a phase of its life cycle as a parasite on Juniperus species, such as red cedar or ornamental junipers and a part of its life cycle on apple or crabapple trees.

Cedar-apple rust can be severe on apple, therefore Henderson County apple growers are more aware of this disease than most homeowners. Infections of apple fruit result in lower fruit quality and early fruit drop. Leaf spots may cause early defoliation, especially during dry summers. If trees are defoliated several years in a row, they become weakened and stressed. Fruit bud formation may be reduced after one year. The disease is not as harmful to juniper, causing galls but not severely affecting plant vigor.

Entertaining Video form Utah State Extension

I got a great chuckle out of this video produced by Utah State University Extension. Take a few minutes and enjoy the hard work put into this video of "Gnome Control in the Garden".

Henderson County residents can dispose of expired medication at four Ingles locations Saturday, March 20th.

Operation Medicine Drop takes place from 10 a.m. to 4 p.m. at the Howard Gap Road and Highland Lake Road Ingles in Hendersonville, as well as the Fletcher and Etowah locations.

See my previous post from November 13th for more information on the importance of keeping medicines out of our waterways.

Wood Ashes as Soil Amendment

Wood ashes are often used as a soil amendment. They contain potash (potassium), phosphate, boron, and other elements. Wood ashes can be used to raise soil pH; use twice as much wood ash as limestone for the same effect as lime. Ashes should not come into contact with germinating seedlings or plant roots as they may cause root damage. Spread a thin layer during the winter and incorporate into the soil in the spring. Check pH yearly if you use wood ashes. Never use coal ashes or large amounts of wood ash (no more than 20 pounds per 1,000 square feet), as toxicity problems may occur.

Time to Think about Preemergent Herbicides

It is time to think about preemergent herbicide applications for summer annual weed control in turfgrass environments. Preemergent herbicides offer a great option for select annual grass and broadleaf weed control in warm- and cool-season turf. Preemergent herbicides are commonly used for crabgrass and goosegrass control but also control other grass and broadleaf weeds propagated from seed. As with any herbicide, one must be mindful of the herbicide mode of action. Specifically, with preemergent herbicides, application timing, application coverage, and single versus split applications among other factors are crucial to the results obtained.

Preemergent herbicides are typically applied late winter for control of many summer annual weeds, particularly annual grasses including crabgrass and goosegrass species. Application timing is critical with these products to obtain desired results. Specifically, smooth and large crabgrass germinate when 24 hour mean soil temperatures (four inch depth) reach 55 degrees F whereas goosegrass germinates when 24 hour mean soil temperatures reach 60 degrees F. Since these herbicides control susceptible species as they grow through the herbicide treated zone, the herbicide barrier must be established prior to weed seed germination. In most areas in NC, this occurs in mid- to late-March. If you are not able to track 24 hour mean soil temperatures on-site, you can visit this site and find a site in your geographic region to track 24 hour mean soil temperatures.
