As many of you know, the window of opportunity is opening up for foliar applications on mesquite. Typically, mesquite can be sprayed starting in the spring once the soil temperature reaches 75 degrees at 12-18 inches deep and the leaves change from a pea green color to dark green. It’s important that the plants have a full, healthy leaf crop to be able to move enough herbicide into the bud zone. In our part of the state, spraying can continue throughout June and July.
- Foliar Applications – The best option is a herbicide called Sendero. Works well on mesquite that is 4-5 foot tall with plenty of foliage. When the plants get much taller, the challenge becomes getting good uniform coverage over the plant.
- Basal Applications – The best option is a mixture of 25% Remedy and 75% Diesel. This approach can be done anytime of the year under good growing conditions. Works well on plants with one or two basal stems.
The video below gives a good illustration of the proper techniques associated with foliar and basal applications.
