Pine Bark Beetle Control with Monty’s Plant Food Products

The Pine Beetle continues to be a problem for residents across a broad swath of the country. Below is a control method that one ID arborist has used for the past several years for help controlling the pest for his customers.

Those who are now also dealing with the Emerald Ash Borer may also consider a similar treatment for their trees.  Though we have no evidence that this program will provide definitive results for the Ash Borer our experience with the Pine Beetle lead us to believe it may be worth a try in your area.

Monty’s Protocol for Treating Infested Trees
 
The following is a protocol which Drew Andrew developed in his business as an Arborist in Idaho over the past four years. This is the sole treatment he uses on his customers trees and woodlands. He does not use insecticides which require strict licensing requirements and can further harm the environment. While this treatment has not been validated by replicated academic trials, anecdotal evidence would support his success in a variety of settings.
Again, this treatment will not treat nor destroy the insects themselves but has shown promise in preventing attack and saving trees already infested with pine beetles. For complete treatment, we advise that you consult with an arborist, your local county extension or other professional for insecticides approved for use in your area for treatment of pine beetles.
 
As a rescue treatment follow the below guidelines two to three times per year. As a preventative, or to discourage re-infestation of previously affected trees apply annually in the spring as the trees break dormancy.
  • Prepare 18-24 ounces of Monty’s 2-15-15 Formula in 25 gallons of water in a spray tank suitable for spraying trees.  
  • Set PSI to 35 lbs of pressure on spray tank.  
  • Thoroughly saturate the trunk of the tree from the base to as high as you can reach. 
  • Spray mixture into any visible holes where possible. 
  • Combine bark treatment with a foliar application to the needles, or crown, of the tree when possible.

 For heavy infestations and if the tree is already showing significant signs of browning at the crown,combine all above steps with the following:

  • Root drench the above mixture with a deep feeder from the base of the tree to the edge of the drip line. 
  • Additionally, drill small ¼ inch holes into the trunk of the tree just past the outer bark layer and inject 1-2 ounces of solution per hole.

 Additional results may be noticed by adding 16 ounces of Monty’s Liquid Carbon or by using this as a tank-mix with your insecticide of choice.  Always read and follow label directions on any insecticide you may use.

Spring is coming; time to prepare for the emerald ash borer

Below is an article released by the cooperative extension service of the University of KY.  The information is new for KY residents and maybe helpful to other states where the Emerald Ash Borer already exists, or for places where it may migrate this season.

If you suspect EAB infestation, you might consider using Monty’s products as part of a treatment program.   You can see a description of that treatment program here.   While we have no definitive evidence that this program will help with EAB control, our program has shown success in ID in control of Pine Bark Beetles and would tend to indicate at least some help may be available in preventing outbreaks on your property. 

LEXINGTON, Ky., (Feb. 24, 2010) – In 2009, the emerald ash borer

turned up in Kentucky. Bluegrass state residents knew they probably couldn’t dodge the bullet forever but still hoped to keep the devastating insect pest at bay for as long as possible.

“Now that the EAB is in Kentucky, it’s likely here to stay,” said Amy Fulcher, University of Kentucky College of Agriculture extension associate for nursery crops. “Entomologists anticipate that seedling ash trees in unmaintained areas in and near infested urban areas will sustain EAB populations.”

So with the emerald ash borer a seemingly permanent resident, Kentuckians must decide how to care for ash trees in home landscapes and municipalities. Fulcher and UK Consumer Horticulture Specialist Rick Durham believe that residents and city planners can help maintain healthy urban forests by removing ash trees and replacing them with other species or treating their existing trees to control the insect.

“It’s not too early to begin considering which strategy to pursue,” Durham said.

Durham said that landscape contractors and arborists often provide ash removal and replacement as well as emerald ash borer treatment services for preserving ash trees.

“You have to consider many factors before choosing an EAB management strategy,” he said. “The health, location and size of the ash tree will have an impact on the value of the tree.  A tree with mower or trimmer damage, existing pest damage, poor location (under power lines or too close to a structure), poor planting (too deep, nylon twine intact), previous topping, or dieback or other defects would be less valued than a tree with proper placement and healthy roots, trunk and branches.”

Fulcher added that a tree in poor health would be less able to take up the pesticide and thus, tree health will impact treatment success.

“Sentimental value, tree size, presence of other tree species and significance of an ash tree can also impact the value of the tree and will vary from person to person,” she said.

Fulcher said trees larger than 22 inches in diameter often cannot take up sufficient quantities of pesticide to adequately protect the tree, although future products may make that possible.

“Large trees are expensive to remove and replace but also the most costly to protect,” she said. “Small ash trees are less expensive than larger trees to remove and replace but also the least expensive to treat. Because a small tree can be removed and replaced relatively inexpensively and eliminate the need for protracted EAB treatments, small trees are ideal candidates for removal and replacement.”

Durham said homeowners and landscapers can purchase replacement trees relatively inexpensively.

“The weak housing market and generally poor economy have led to decreased trees sales and, as a consequence, prices have substantially dropped,” he said. “These savings at the wholesale price level are often passed down to the consumer, which means homeowners are having an unprecedented opportunity to purchase trees inexpensively.”

Once a homeowner or landscaper makes the decision to replace an ash tree, it’s often difficult to choose what species will take its place. Fulcher emphasized that while it may seem easy to suggest a list of trees for possible replacement, landscapers should take care to ensure the replacement tree is right for the individual site.

“A local arborist or nursery professional can help you make this decision,” Fulcher said.  “Some things to consider include the potential mature height of the tree being planted, particular soil conditions (wet, dry, alkaline, heavy clay), whether or not you hope to grow grass under the tree, desired fall foliage color, or desired spring flowers.”

Fulcher recommended landscapers also consider whether the selected replacement has resistance to particular pests and keep in mind that the selection must be adapted for Kentucky’s climate. 

If the tree produces fruit, such as crabapples, consider whether it is a good match for the site. Crabapples planted near sidewalks and driveways may result in slippery surfaces once fruit begin to fall, she said. A brochure that lists acceptable street trees for Lexington can be found by entering the term “street tree” at http://www.lexingtonky.gov. City or county governments may have similar information available.

“When considering management strategies, be sure to ask for a Certified Arborist or a Kentucky Certified Nurseryman,” Durham added. “Ask about how the treatment will be applied, by drenching or injecting the tree; the consequences of each application technique and how long the pesticide application is expected to last. And, if your new replacement tree was grown in Kentucky, ask for the Kentucky Proud logo.”

Fulcher and Durham stressed that people need to remember not to move firewood that comes from ash trees.

Gentlemen (and ladies) Start Your Engines

I have a confession to make.  I hate the sound of vacuum cleaners.  Don’t know what it is.  Maybe it is some fear from my childhood tied in to the fact that vacuuming the house was always my job, but if you want to chase me from a building, fire up the vacuum. 

Oddly, as much as I hate the sound of a vacuum I love the sound of a lawnmower.  Even at 6 am on Saturday Mornings that familiar putta-putta-putta of a mower engine gets me in a good mood.  I am waiting for these late winter clouds to dissipate so my neighbors and I can join the cacophony of spring time with our mower symphony.  Till then, all I can do is wait.

However to make usre your mower sings rather than sputters, check out this article from acreage life e- magazine.  It will guide you step by step on the maintenance that you need to do now, so you will be ready to assault those first few blades of grass.

Pruning Roses for Winter Dormancy

Monty Justice Applies Liquid Carbon to his Roses

Want to know when to Prune your Roses?  Well me, too.  And when I need to know ANYTHING about roses, I check with Monty Justice.    He is one of the co-founders of Monty’s Plant Food Company, a frequent rose judge, columnist, and owner of his own rose care company. Oh, and did I mention that he is an octogenarian?!  So, when he speaks…I listen.

Here is his advice on pruning roses.  (note:  He lives in Kentucky.  You may need to modify your schedule slightly to accomodate your particular growth zone)  Just bear in mind that pruning should be done between the FIRST blooom cycle and before NEW SPRING growth appears.

In the fall, crowns and bud unions should be just below ground.  You can do what I call “pre-pruning” after a frost or temperatures in the 30 degree F. range before the plants are dormant.  Remove damaged, twiggy, crossover stems and foliage, a foot or more from the ground.  Also open up the congested middle by taking out one cane to the ground.  You can do this when temperatures are moderate.  Do nothing to the length of remaining stems or leaves.  Continue to add Monty’s 2-15-15 every time you spray.

 Before the soil warms and new growth begins, (March) do a final pruning – remaining leaves and buds, and tiny laterals at the top of each rose plant.  Seek a uniform height by shortening stems above five feet.

 Begin spraying with your accustomed fungicide and insecticide when the buds are pea size and or the “purplish-red” leaves are turning green.  Disease and insects will not attack until this change takes place.  Add one tablespoon of both vinegar and epsom salts plus one half teaspoon Monty’s 2-15-15 to each gallon of spray material.  No need to add a spreader sticker if Monty’s is added.  The humics in Monty’s takes the pesticides and nutrients into the plant effectively through the leaves and buffers the potential for burn or other damage. The vinegar acidifies the solution making the pesticides retain their viability for an extra day or two.

            Magnesium is significantly important and provides three specific benefits.  

  • It boosts the efficiency of photosynthesis and makes the process of turning sunshine into energy more effective. 
  • It also keeps the lower leaves darker green at least until they are shaded by the foliage above
  • It helps the plant metabolize other nutrients.

 Using the spray nozzle apply Monty’s Liquid Carbon soil conditioner on the rose bed four times at a rate of 2 ounces per 1,000 square feet.  Allow one month between each application for any source of water to take the humic material into the soil.  This treatment is most effective on clay soils.  Do not use if soil has already been conditioned more than six inches deep with compost etc.

 At the end of the first bloom cycle, (May-June) remove all lateral stems that did not bloom and cut back all canes to a desired thickness (one quarter inch).

             In summary, your larger plant size will have increased roots.  The abundance of leaves will increase the energy and vigor of the plant.  Removing a goodly percentage (25 to 40 percent) of the stem and foliage creates an imbalance between roots and the top growth.  This will result in increased vigor, new larger canes, and more blooms for the remaining season.

             Although I’ve not done this with Fortuniana rooted roses, I can see no reason it will not do as well as other root stock.
