Plan to Introduce a New Cashew Variety

The Tanzania Agricultural Research Institute, through the TARI-Naliendele Centre, is planning to introduce a new cashew variety that can resist leaf blight and other cashew diseases.

Dr. Fortunus Kapinga, Director of the TARI-Naliendele Centre, recently revealed that the new variety could be grown without the use of chemical pesticides.

He said: “We are in the final stage of introducing a new variety that can be grown and managed well without using chemical pesticides to control the disease.”

This development comes after complaints from cashew farmers in Tanzania about severe attacks of leaf blight disease on cashew trees. The disease has caused serious damage and significant yield losses in many cashew-growing areas.

Changing Weather Increases the Risk of Cashew Disease

According to Dr. Kapinga, cashew disease in Tanzania is mainly linked to changing weather patterns, especially rainfall and humidity.

He explained that recent cashew disease outbreaks in Tanzania have become more destructive than before. The disease can spread very quickly after rainfall, especially when humidity remains high.

Speaking to the press, he said: “In the past, the disease appeared after rain, but now the wet conditions are causing greater damage to crop yields.”

Tanzania’s Cashew Harvest Has Been Badly Affected

Cashew farmers said that cashew production has been heavily affected by several pests and diseases, including leaf blight, leading to poor harvest results.

Ms. Khadija Bakiri, an agricultural consultant in the Lindi Region, said the region has been seriously affected by pests and diseases caused by climate change.

She explained: “The Lindi Region has been heavily affected by pests and diseases, especially in cashew farming. Several diseases have limited cashew production in this area.”

Ms. Bakiri also said the region had expected to harvest more than 100,000 tons of raw cashew nuts in the 2022/2023 season. However, this target may not be achieved because pests and diseases have damaged the crop.

In the 2021/2022 season, the Lindi Region harvested more than 65,000 tons of raw cashew nuts.

She added: “In the 2022/2023 season, we do not expect to harvest less than the 65,000 tons of raw cashew nuts that we harvested in the previous 2021/2022 season.”
