A state of emergency has been declared in the tomato sector in Kaduna state, northern Nigeria, local media report.
A moth called the Tomato Leaf Miner or Tuta Absoluta has ravaged 80% of tomato farms, Commissioner of Agriculture Daniel Manzo Maigar told the press.
He calculated a loss of at least 1bn naira ($5.1m; £3.5m).
The price of a basket of tomatoes has increased from $1.20 less than three months ago to more than $40 today.
A tomato paste manufacturing business owned by Africa’s richest man, Aliko Dangote, suspended production earlier in the month due to the lack of tomatoes, reports Forbes.
Mr Maigar was reported as saying officials from the ministry of agriculture have gone to Kenya to meet experts on the Tomato Leaf Miner.
