Mojave 70 EG should not be applied where the chemical may contact the roots of desirable trees or other plants. Roots of trees and shrubs may extend a considerable distance beyond the branch extremities; i.e., drip line.
Mojave 70 EG is a professional vegetation management product which should only be used by an experienced applicator, as it can leach to surrounding areas and cause unintended ground sterilization. The general application rate for Mojave 70 EG is 0.5 - 1 lb. per gallon of water, and you should refer to the manufacturer's product label for complete application instructions, and only use as directed.
Because privet is very tough to control, we would suggest cutting the privet and then applying a product with the active ingredient Triclopyr like Fertilome Brush Killer and Stump Killer by brushing the undiluted product onto the freshly cut stumps, which will work to kill the entire root system in 1-6 weeks. You can refer to the manufacturer's product label, and use as directed.
Mojave 70 EG absolutely has the potential risk for migration or movement in the soil with heavy rains if the product is applied to a slope. We would not recommend using Mojave for that area to avoid impacting plants downhill or nearby the treatment zone.
Avoid applications of Alligare Mojave 70 EG to powdery-dry soil or sand soils when there is little likelihood of rainfall soon after treatment, since subsequent off-target movement of treated soil by water and/or wind may cause damage to adjacent desirable plants or crops. Please review the full label prior to application for full details on rainfall, irrigation etc. Mojave is known leacher so best to apply when there is not a lot of rain fall expected within about a week or 2 of application
