Spraying the weed with herbicides while it is still young is another effective approach that can be taken. Alternatively, there is need to control the weed before it sets the seeds. This entails that the growers should strive to tackle the fleabane while it is still young. They should use the cultivators to bury the weed before it matures since it would become resistant with age. There are quite a number of benefits that can be derived from this action. For instance, the growers will not experience the recurrence of the problematic weed and this can also help to improve the yield. Persuasion channels like television can be used to appeal to the growers to follow the steps suggested above. On the other hand, Silverleaf whitefly (SLW) remains a potentially serious pest of coastal soya beans in the northern region. The main problem is that it quickly develops rapid pesticide resistance usually in a single season. It is also adaptive to high temperatures. The SLW cannot be managed by the use of pesticides alone and growers are not advised to use these since they kill the SLW parasites and predators allowing the pest to multiply unchallenged. Integrated pest management (IPM) is essential in order to combat this problem. There is the need for the growers to understand the basic tenets of this strategy as well as the measures that characterize it. The IPM strategy entails that the growers should ensure that there are natural predators in the crop that can suppress the pest’s population. The growers should try to maintain a natural balance in the ecosystem where the predators will feed on the SLW and this helps to ensure that the SLW does not multiply in numbers. The benefits that can be achieved by the growers of beans is that their crop will not be destroyed by the pests.
