Pests and diseases are the major reasons why many agribusinesses fail. They increase the loss of cassava which should have contributed to your overall profit.
The major pests and diseases ofcassava are:
1.Thrips and Mites:
Can be controlled using arecommended miticide and Insect Growth Regulators.
These pests are prevalent duringdry periods and decreases as rainfall increases.
2.African cassava mosaic virus:
The African cassava mosaic viruscauses the leaves of the cassava plant to wither.
When such withering occurs, itlimits the growth of the root. The best control measure is to plantresistant varieties.
This causes a reduction ininter-node length of cassava stem. This pest can cause up to 80% croploss, which is extremely detrimental to the production of subsistencefarmers.
Some insects affect the plantdirectly. For instance, locusts feed on cassava leaves.
Ants and termites eat up cassavastems as soon as they are planted, or later in the season; thereforedestroying whole plants.
Others affect the plant indirectlyby the transferring virus into the plant. Use recommendedinsecticides and Insect Growth Regulators to control insects.
Grass-cutters, pigs, goats, andsheep frequently expose and eat up roots in the soil. The damage tothe roots can provide an entry for the microorganisms that causeroots to rot.
To prevent this, Keep the farm andits surroundings weed free. Use traps and poisoned grains to killthem or wire mesh fencing to prevent them from entering your field.
