Agriculture is still the most important source of income and the largest economic sector in the world. In particular on the African continent, small scale farmers and subsistence farmers produce a large part of all the food that the population eats. They face the challenge of cultivating their land with rudimentary tools in the most effective way and often reach the limits of their livelihood. In addition, there is often little knowledge about agricultural land use and the use of crop protection products. For DVA as a company, assuming social responsibility means not only providing suitable products, but also ensuring that they are used correctly. This means correct dosage, compliance with safety regulations and application. To this end, we carry out field trials and product demonstrations on a regular basis in which farmers and distributors take part in order to share our knowledge with them.

Edwin Inziani from DVA East Africa is part of our Team and offers technical support and solutions to farmers with the aim to reduce their costs, improve quality and increase the output.

Efficiency and sensitivity evaluation after the use of herbicides for coffee

During our field trials we test the effects of our herbicides on unwanted plants such as grasses, sedges and broadleaf weeds that compete with the plants for nutrient and water. These include weeds such as black jack, stargrass, cormelina, hyperenium and others.

For an optimal evaluation of the test results, the initial situation is recorded such as:

• • When was the crop planted?
  • Which irrigation system was used to irrigate the field?
  • When was the experiment last watered?
  • How much precipitation was there in this time.
  • Average temperature.
  • How large was the area?
  • What equipment was used.

After the experiment has been carried out, a toxicity assessment will be made, documenting the effects on the culture, among others:

• • Peak burns
  • Leaf distortion
  • Arrears
  • Bud burning

The square metre method is used to evaluate bio-efficiency, which is achieved by looking at the decline of weeds after each application. The sensitivity of the coffee plant is also taken into account. We use appropriate statistical methods and a simple graphical representation to ensure a scientific interpretation of the results.

The results of the DVA trials form the basis for recommendations to farmers on appropriate application quantities and techniques and contribute to sustainable production.
