To avoid pests in beans, plant early to ensure that the little rain you get will help you and that is why those who plant beans this season are reaping better than those who planted maize.
Pests attack beans in the dry season and they are usually planted late thus affected by the sunrays. This calls for watering of beans. You plant pest resistant crops. Resistant does not mean that you do not get affected, you get affected but it means nothing to your productivity. For commercial farmers, you apply judicial chemicals to avoid a loss because in most cases we advise not to use pesticides.

How can we control pests from spreading?

While you are rotating your crops, it is better you rotate with different crops that do not harbor or share diseases with each other. If you plant beans this season do not plant beans next season because if they have a disease it will be easily spread, and do not even allow volunteers (crops growing emerging on their own) however much nice looking they may be because they carry the disease to another season.
