Boron Deficiency in Florida Citrus Groves
chlorosis, but the addition of urea to the solu tion appeared to enhance the effect of the biuret. Experiment 4. When different amounts of commercial urea and crystalline urea were ap plied to the soil, 10 weeks were necessary for the chlorosis to appear on the trees which had received 60 and 80 grams of the commercial urea. No chlorosis resulted from the crystal line urea. Experiment 5. As a r...
متن کاملMathematical modeling of citrus groves infected by huanglongbing.
Huanglongbing (citrus greening) is a bacterial disease that is significantly impacting the citrus industry in Florida and poses a risk to the remaining citrus-producing regions of the United States. A mathematical model of a grove infected by citrus greening is developed. An equilibrium stability analysis is presented. The basic reproductive number and its relation to the persistence of the dis...
متن کاملAcoustic surveying of subterranean insect populations in citrus groves.
Subterranean insect pests cause considerable economic damage but their concealment makes detection difficult. A portable acoustic system was developed and tested for its potential to rate the likelihood that trees in citrus groves were infested with Diaprepes abbreviatus (L.) larvae. The likelihood was rated independently by a computer program and an experienced listener that distinguished inse...
متن کاملIFAS Citrus Initiative Annual Research and Extension Progress Report 2008-09 Mechanical Harvesting and Abscission
Detailed Accomplishments in 2008-09: Processors are concerned about peel integrity of CMNP-treated fruit. We conducted 2 trials in March and April with Valencia oranges to determine the postharvest effect of CMNP applied to canopies for the purpose of loosening fruit on fruit crush force, peel puncture resistance, and peel puncture depth. Fruit were collected during our harvesting trial studies...
متن کاملMechanical Harvesting Has Little Effect on Water Status and Leaf Gas Exchange in Citrus Trees
Mechanical harvesting of citrus trees can cause physical injuries, such as shedding of leaves, exposing roots, and scuffi ng bark. Although mechanical harvesting usually has not reduced yield, physiological consequences to the tree from these visible injuries have not been investigated. We hypothesized that physical injuries to tree canopies and root systems from a properly operated trunk shake...
