Treating bush encroachment restores grazing land by allowing grass to recover, giving livestock access to better-quality feed. This leads to healthier animals, improved weight gain and milk production, and a higher carrying capacity without overgrazing. Open veld also improves airflow and sunlight, which helps reduce ticks, parasites, and disease pressure in herds.
Encroaching species use large amounts of groundwater, so controlling them supports better water availability for both livestock and farming operations. Over time, restored veld improves farm management, lowers supplementary feeding costs, reduces fire risk, and increases long-term productivity and the overall value of the land.
Terravusa is proud to offer a range of tailor-made herbicide solutions to help livestock and game farmers manage encroaching species in their pastures. Two of the latest products in the Terravusa range are Mevazue 250 EW and Sendero 336 SL.

1. Aminopyralid
A selective active ingredient used for control of broadleaf weeds.
It is in the picolinic acid family of herbicides which also includes clopyralid, picloram and triclopyr.
It does not affect grass species.
Aminopyralid disrupts plant growth metabolic pathways, affecting the growth process of the plant.
Non-bio-accumulative in animals, no carcinogenic carry-over to humans through meat and milk.
Keep away from any irrigation water body / river / canals.
Keep away from cultivated fields / orchards.
Aerial application of a liquid, rather than a granule, is more selective as the product is only taken up by the leaves where it is applied. No target damage is done due to product leaching or uptake through the roots.
It is very selective, and the active ingredients only control specific tree species (mainly leguminous trees) such as Sickle bush, Black thorn and Sweet thorn (predominantly encroacher species).
The active ingredients are not harmful to people or animals.
2. Chlopyralid
a) A selective herbicide used for control of broadleaf weeds.
b) In the picolinic acid family of herbicides which includes aminopyralid, picloram, triclopyr.
c) It does not affect grass species.
d) Known for its ability to persist in dead plants and compost.
e) Mimics a plant growth hormone and causes uncontrolled and disorganized plant growth that leads to plant death.
f) Non-bio-accumulative in animals, no carcinogenic carry-over to humans through meat and milk.
g) Keep away from any irrigation water body / river / canals.
h) Keep away from cultivated fields / orchards.
The active ingredients are not harmful to people or animals.
It is a liquid formulation applied by air by means of a fixed-wing aircraft or helicopter at a spray mix rate of 40 liters per hectare. Drone applications are also gaining increased popularity.
Aerial application of a liquid rather than a granule ensures more even and effective distribution of the active ingredients to reach the target plants.
The product’s efficacy is not influenced by soil clay content.
It can be applied with much greater accuracy to smaller areas by helicopter and even drones.
It has no negative impact on grass species, so natural grazing is not affected. Good grazing grasses return very quickly after application, as the dead trees do not use the available water and nutrients in the soil anymore.
Where good grazing grasses establish, it suppresses free seedlings that germinates from the seedbank from taking over the target area again.
The dead tree material can be harvested two years after application – therefore work creation is stimulated in rural areas through guaranteed harvesting of safe firewood for resale.
The active ingredients are not harmful to people or animals, since they only contain synthetic plant hormones.
Cattle and game in the areas of application do not need to be removed prior to application.
The product’s characteristics means that very large areas can be treated in a short time.
Trees that remain in peripheral infestation areas that is not feasible to treat aerially, can easily be controlled by means of knapsack sprayer application of Sendero 336 SL, ensuring further work creation for rural communities.
In South Africa, the primary focus is the effective control of Opuntia species within the Cacti family. This includes addressing concerns related to jointed cactus, prickly pear, queen of the night cactus, and various others.
Notably, Mezavue 250 EW stands out for its benign impact on grass species, ensuring that natural grazing remains unaffected by its application. It also provides a much safer alternative to the current standard, M.S.M.A. 720 SL, which can be extremely harmful to grazing animals.
Mezavue 250 EW is registered for use in South Africa (limited), Namibia, and Botswana. The product has been meticulously designed to be very effective in controlling a wide range of species with a reduced rate of picloram, limiting risk of leaching and off target movement.
Its selectivity towards grass species underscores our commitment to sustainable agricultural practices and environmental compatibility.
Mezavue 250 EW can be applied through fixed-wing aircraft or helicopter at a spray mix rate of 40 liters per hectare.

d) Mode of action:
i) Acidify the plant cell walls.
ii) Plant cell walls tear loose.
iii) Causes uncontrolled growth.
