We have recently posted an article on dry beans and how to increase their yields with plant nutrition and make it more profitable (if you haven’t read it yet, here is the link -link to “What you need to know about dry beans” article -. With an increased interest of farmers in growing dry beans, the importance of dedicating a whole article on its pests was noticed. Therefore, throughout this text, the major pests in each phenological state of the plant will be introduced, together with some inputs on how to prevent them.

Dry beans are also in the i-Plant Nutrition database and can be selected for the creation of fertilizer plans when using the software.

Seeds, seedlings and roots’ pests:


The occurrence of an underground pest population is related to the presence of host plants (usually weeds) near sowing time. The incidence of soil pests can be decreased by eliminating host plants, such as weeds or corn, at least three weeks before sowing. This will decrease the oviposition of moths in these areas thus avoiding the presence of large caterpillars (beyond 3rd instar), which cause greater damage to the crop in the initial development phases.

Pests that will scratch and suck:


Bug attractive traps might help monitoring the pest population as well as in their control. Getting rid of this kind of dry bean pest might implicate on the use of chemical pesticides or its combination with biological enemies, such as entomopathogenic fungi and egg predators.

Stalk and stem pests:


In order to control the pests in this stage, it is essential to integrate different control measures, such as crop rotation, chemical and mechanical control during soil preparation, sowing and also on the field’s surroundings. These insects need to feed off legumes once they emerge, therefore, rotating the plantation with maize, sorghum or sunflowers, for example, will force them to leave the field in search of food.

Pod pests:


The best way to control pod pests is by planning the whole season beforehand. Planning the best sowing date, when to apply pesticides according to the plant and pest stage, planning the harvest… Therefore, efficient pre-harvest planning will help you avoid unnecessary costs and yield loss in the future.

Just like the human body, healthy and well-nourished plants have greater resistance to pests and diseases, and in case of infestation, will have their productivity less affected.
