Control of Citrus Flush Timing Could Improve Psyllid Control
They say timing is everything in life, and that’s certainly true of the Asian citrus psyllid, which has devastated Florida agriculture for the past decade by transmitting citrus greening disease, also known as huanglongbing or HLB. To reproduce, this small, flying insect must lay eggs on citrus “flush” – the tender new leaves and shoots that citrus trees produce several …
New Florida Citrus Production Guide Debuts at Citrus Expo
Beginning this week, Florida citrus growers will have an updated resource to help them keep groves productive despite the ever-present threat of huanglongbing, the bacterial malady also known as HLB or citrus greening disease.
