Using chemicals on shrubs to get rid of or avoid insects and diseases requires attention to detail when it comes to diluting and program prices. When using Spectracide to get rid of insects, the particular amount for each shrub rides on the entire height of the shrub. Treating fungal issues with Spectracide is not as precise but the right dilution rate is important to avoid damaging the leaves.
Ounces According to Height
Spectracide Tree Shrub Insect Control Concentrate Drench Spray is intended to penetrate shrub roots to treat and prevent borers, various species of beetles aphids and scale insects. Measure how tall — at feet — the shrub is in the soil to the peak of the canopy. Multiply the height of the shrub by 3 then translate the resulting amount into ounces. For instance, you’d use 15 ounces of Spectracide tree shrub insect control concentrate on a 5-foot-tall shrub. For a 1-foot-tall tree, then you only need 3 ounces of the goods.
Ounces per Second
The insecticide bottle comes with an attachment to the hose and you measure the program in seconds. Multiply the ounces you intend to apply by 5 to get the program time. For the 5-foot-tall tree, then multiply the 15 ounces you intend to apply by 5. Spray the soil around the trunk for 75 seconds to distribute 15 ounces of Spectracide. For a small 1-foot-shrub, spray for 15 seconds to distribute 3 ounces around the base. Use a timer or a stopwatch to help determine the application rate correctly. The chemicals work by penetrating the soil and also functioning at the main level so that it’s only effective when the ground isn’t frozen or muddy from heavy rain or watering.
Combating Fungal Problems
For fungal issues, like rust, leaf spot and powdery mildew, Spectracide makes Spectracide Immunox Multi-Purpose Fungicide Spray Concentrate For Gardens that functions on shrubs. Rather than measuring an exact application rate for each shrub, dilute the concentrated substance at a rate of 1 ounce for each gallon of water. With a backpack or hand-held sprayer, you use the diluted fungicide directly on the leaves until they are wet, but not quite dripping. Follow up every a couple of weeks before the issue goes away.
Always allow places around shrubs to dry completely before you allow kids, pets or people into the area. When you consume a container which has included fungicides or pesticides, poke a hole at the bottom. This keeps anybody from filling it with a consumable liquid. Wind picks up and distributes moisture particles, so work on a windless day to safeguard yourself and your neighbors. Put on a mask, long protective clothing and masks while you work and clean all your clothing thoroughly after finishing the task. If kids, pets or adults consume the product, get them to the hospital straight away. Always double-check the instructions on the label because products fluctuate and the dilution rates may change over time, too.
