(CDC) - Due to the low groove through the North Central combined with strong Southwest wind caused heavy rain in many places in the Central Highlands provinces. The day-long rains incessantly caused rising moisture, fast-growing foliage, low light photosynthesis, is favorable condition to black fungus parasitic on the coffee stem grow and the coffee trees are hard to supply nutrients to provide coffee fruit, it is the cause of dropping premature fruit in hundreds hectares coffee.
Dropping premature coffee fruit
Observed in many coffee plantations, between the green fruit bunches leftover are blackened stalks - traces of dropped fruit. In many trees, all of the fruit have fallen off only the bare branches and leaves, dropped rate up to 5-10%.
In addition, the flowering period of coffee trees suffered drought. Drought lasted from early June to the end of June has also created favorable conditions for aphids thrive on coffee trees.
In total 1,077 ha coffee in Tam Bo (Di Linh district, Lam Dong province) has 150 hectares infected by aphids at average level with the rate of 11.5% (some trees damaged heavily); although the remaining area is still infected by aphids but the damaged rate is insignificantly (only 7.5% or less).
The Central Highlands has about 561,500 ha coffee. In the next 10 years, more than 100,000 hectares coffee in the Central Highlands will be agging, when ending business cycles they need to be recultivation or cut to recovery, select bud to regeneration, connect to "rejuvenate" coffee plantations.
Thus, in the flowering period, coffee platation suffered prolonged drought and then on fruiting period, coffee tree continued to suffer black fungus infection in stem and fall, hundreds of coffee growers have to face with a failures season, along with low productivity due to high rate of old coffee, the coffee production in 2014/15 crop year is estimated lower than the previous years.
