Improve Water and Nutrient Retention With Compost and Biochar
By Tripti Vashisth, Abhishek Neupane and Taylor Livingston Florida citrus trees are under pressure from huanglongbing (HLB). The disease weakens root systems, reducing the tree’s ability to take up water and nutrients. Compounding this issue, most Florida groves sit on sandy soils with very little organic matter. These soils drain quickly, struggle to hold nutrients and allow both water and …

Match the PGR to the Purpose at the Proper Time
By Tripti Vashisth and Prudhvi Vulchi Plant growth regulators (PGRs) have become an important management tool for Florida citrus growers facing the challenges of huanglongbing (HLB). HLB disrupts the tree’s hormonal balance by reducing growth-promoting hormones like cytokinin and gibberellins and increasing stress-related hormones. This imbalance weakens carbohydrate transport, reduces sink strength and accelerates canopy decline. PGRs can help restore …

A New Step Before You Spray
By Matt Smith The pesticide label is going online — kind of. I’ll explain, but the main takeaway is that a new step before spraying is required from now on. It’s not particularly difficult, but it is going to add to your pre-spray paperwork and planning. Why is this happening? After multiple lawsuits, judges reaffirmed that the Federal Insecticide, Fungicide, …
Georgia Needs Management Plan for Citrus Greening
Citrus greening disease has yet to find its footing in Georgia’s commercial citrus. But if it does, Georgia’s growers need a plan in place to manage the disease.
