Cut stumps of Prosopis juliflora treated with Triclon (René Eschen, CABI Switzerland)
The technology is highly relevant and effective for controlling the invasion of Prosopis spp. in both agricultural and grassland areas where the species is considered problematic. It is particularly suitable for dry regions prone to Prosopis invasions, especially those experiencing drought periods of more than four months, which allow the herbicide to take significant effect. To avoid chemical contamination, the technology should only be applied in areas located more than 200 meters away from water sources.
This method requires simple tools to cut trees efficiently, with a chainsaw being recommended for the task. However, in areas where infestations cover less than 20 percent of the land, simpler tools such as machetes can be used. Trees should be cut as close to the ground as possible (no more than 15 cm stump height), and herbicide should be applied to the stump within three minutes of cutting. The treatment should be carried out during the dry season, ensuring no rainfall is expected within a month to allow for complete absorption of the herbicide.
A minimum of two people equipped with proper protective clothing is required for this operation: one to cut the trees and another to apply the herbicide and clear the cut branches. The herbicide, typically Triclopyr, is often mixed with diesel at a 1:50 ratio. A follow-up application is crucial to target any trees that were not completely killed during the initial treatment.
Herbicides can be ordered from Arysta Co. Ltd in Tanzania at a cost of TZS 1,000,000 (USD 430) per 20 liters. The advantages of using this technology include its effectiveness in killing the trees and the ability to utilize the cut branches as fuelwood or for making Prosopis charcoal. However, the major drawbacks include limited information leading to scepticism among land users regarding the health risks and potential long-term effects on soil quality, as well as the limited availability of the herbicide in local agro-stores.
