Spraying is the most pest management practice that is needed to be integrated by the farmers in their successful farming. And in order to control pests and diseases from destroying their crops and preserving soil nutrients while increasing crops ‘health and harvest’.

It will match with the growing of plants which will be either bush or climbing plants and this will give the right way to spray your crops. As we all know, you may have best chemicals and pesticides but the spraying technique will enable the plants to make effective use of those chemicals. This will save your money and ensure effective systematic productivity.
The previous generation of Enable project of almost 822 participants from at least 250 groups in two sectors, Musha and Munyaga young adults supported by Uyisenga Ni Imanzi in tomato farming. These participants are being trained on the proper spraying technique, which is spraying underside of plants mostly under leaves of plants. This is where the pests are likely to hide themselves, like the fungal diseases which are mostly a challenge and they develop under leaves (www.farmersweekly.com.za 2017). This spraying technique gives good coverage of the top of the leaves rather than usual spraying on top of the plants where the chemical can be easily washed away in rainy season. Moreover, no pests are likely to be found on top of the leaves because they can be exposed to the sunshine that is not good for them. It will need a lot of time and a powerful sprayer unless you are using a curve shaped (u shaped) brass sprayer nozzle.
Initially the training was structured as TOT to all group leaders on spraying technique and other necessary practices, such as mixing chemicals and effective use of fertilizers. Almost all leaders provided the training on the above practices especially spraying. However, the immediate follow ups proved that the technique was less effective on both use of fertilizers and most especially on spraying chemicals which is so important of all which is being talked much in this article as a challenge. Some plots were visited in Munyaga and Musha, to observation the immediate actions taken and challenges of participants and to assess their level of understanding of spraying.

This is obvious that best practitioner come from new farmers of tomatoes who are curious to learn and mostly found in Musha. While those who used to plant tomatoes mostly in Munyaga think they have enough knowledge in planting, and sometimes ignore the acquired techniques recommended. Using examples, realities, observations to the particular plots, repetition of techniques and responding effectively to the questions of participants’ curiosity. That is one way to transform their ways of applying techniques. Observe effectively every land and every step with feedback that gives them the good image of what needed to be improved.
How this challenge addressed and easy way of improving farmer’s knowledge
The exchange visit was planned and completed for both farmers from Munyaga and Musha sectors in which Munyaga the tomato familiar farmers have to visit and learn from Musha new farmers on the chemical use and spraying technique. This was a mutual benefit for both farmers though because Musha were learning about disease phenomenon.
By identify the best practitioner and bad ones and use all examples of realities in the visited fields to help trained get the reality and the above objective of exchange knowledge from each other, it was a random selection of 10 participants from all groups of Munyaga to adapt the skills in this technique and learn from best adapters in Musha.
To sum up all, not only the spraying technique that is a challenge but it is among the big challenges in agriculture practices that gives a sign of better harvest and boost agriculture development.
