Best management practices (BMPs) started in Florida citrus (Citrus spp.) in the 1990s and have evolved to play a major role in production practices today. One of the earliest BMPs in Florida arose from concerns over nitrate-nitrogen concentrations in some surfi cial groundwater aquifers exceeding the 10 mg·L–1 drinking water standard. This occurred in an area of well-drained sandy soils known a...

Huanglongbing (HLB), or citrus greening, is a global citrus disease occurring in almost all citrus growing regions. It causes substantial economic burdens to individual growers, citrus industries and governments. Successful management strategies to reduce disease burden are desperately needed but with so many possible interventions and combinations thereof it is difficult to know which are wort...

Citrus canker is an important bacterial disease of citrus in several regions of the world. Strains of Xanthomonas citri type-A (Xc-A) group are the primary pathogen where citrus canker occurs. After Xc-A entered the Northeast of Argentina in 1974, the disease spread rapidly from 1977 to 1980 and then slowed down and remained moving at slow pace until 1990 when it became endemic. Citrus canker w...

This flowchart is intended to help both commercial citrus growers and home gardeners in properly identifying common diseases on fruit, leaves, stems. Proper identification will determine the appropriate management strategy. Written by Amit Levy, Jamie D. Burrow, Megan M.

Horticultural oils are an important component of integrated management programs of several phytophagous arthropods and pathogens affecting fruit, ornamentals and vegetables in greenhouse and field production systems. Although effective against the target pest, their incompatibility with biological control agents can compromise efforts to develop eco-friendly management programs for important ag...

Abstract. Detecting immature green citrus at an early stage for yield forecasting can help growers expect how many fruit they can harvest at the end of the year. Also, it can provide an in-field spatial variability of fruit that can be used for providing site-specific management of citrus trees to increase yield and profit. Yield forecasting using the machine vision technology has been a promis...

The application of insecticides to control Diaphorina citri Kuwayama (Hemiptera: Psyllidae) is a principal component of the current management for citrus greening disease or Huanglongbing. It is recommended that growers apply systemic insecticides such as imidacloprid and thiamethoxam every 2 mo after seedling planting, but this practice renders the seedlings insecticide-free and vulnerable to ...
