Late-season `Valencia' Orange Mechanical Harvesting with an Abscission Agent and Low-frequency Harvesting

  title={Late-season `Valencia' Orange Mechanical Harvesting with an Abscission Agent and Low-frequency Harvesting},
  author={Jacqueline K. Burns and F. M. Roka and Kuo-Tan Li and Luis Pozo and Richard S. Buker},
An abscission agent (5-chloro-3-methyl-4-nitro-1H-pyrazole [CMNP]) at 300 mg·L -1 in a volume of 2810 L·ha -1 was applied to Valencia orange trees [Citrus sinensis (L.) Osb.] on 22 May 2004. At this time, immature and mature fruit were present on the tree simultaneously. Three days after application, fruit were mechanically harvested using a trunk-shake-and-catch system. The power to the shaker head was operated at full- or half-throttle (FT or HT, respectively), and the duration of trunk…

Abscission Agent Application and Canopy Shaker Frequency Effects on Mechanical Harvest Efficiency of Sweet Orange
The amount of loosening by CMNP was concentration-dependent and facilitated removal, especially with lower canopy shaker frequencies, which indicates that the percent of the total crop harvested should use the actual weight of fruit removed in determining efficacy of CMNP and harvest efficiency of the mechanical harvesters.
Organ Loss and Yield Impacts of ‘Valencia’ Sweet Orange in Response to Fruit Abscission Agents
The use of the abscission agent 5-chloro- 3-methyl-4-nitro-1H-pyrazole (CMNP) in combination with mechanical harvesting increases mature sweet orange fruit removal without causing phytotoxicity to leaves and young developing fruit through most of the harvesting season.
Application of the Abscission Agent 5-Chloro-3-methyl-4-nitro-1H-pyrazole Does Not Affect Peel Integrity or Postharvest Decay of Mechanically Harvested Late-season Fruit of ‘Valencia’ Orange during the Normal Commercial Harvest-to-processing Period
The results indicate that CMNP can be safely used in combination with late-season mechanical harvesting under the conditions described in this study without losses resulting from fruit crushing or decay for at least 3 days, a time period well within the normal commercial harvest-to-processing time of ’36 h.
Better spray coverage can improve efficacy of abscission sprays for mechanically harvested oranges
The selective fruit abscission compound 5-chloro-3methyl-4-nitro-1H-pyrazole (CMNP) improves mature fruit removal of mechanically harvested orange trees in Florida. Uniform fruit removal depends on

Benefits of an Abscission Agent in Mechanical Harvesting of Citrus1
An abscission agent is a chemical compound that when sprayed prior to harvest will induce physiological changes that reduce the picking force to remove mature citrus fruit from the tree. In the
Incorporation of air temperature into a model that predicts loosening of sweet oranges by the abscission agent CMNP
CMNP (5-chloro-3-methyl-4-nitro-1H-pyrazole) is an abscission agent that is in the process of being labeled as an aid for mechanical harvesting. A mathematical model that incorporates the most
Effect of harvesting with a trunk shaker and an abscission chemical on fruit detachment and defoliation of citrus grown under Mediterranean conditions.
It is demonstrated that mechanical harvesting with trunk shakers may be a feasible solution for citrus cultivated in Spain for fresh market.
Effects of Short-term Drought Stress of 'Hamlin' and 'Valencia' Trees and CMNP Application on Fruit Detachment Force, Fruit Drop, and Fruit Quality
Two studies, one on ‘Hamlin’ and the other on ‘Valencia’ trees, were conducted to determine if short-term drought stress affects efficacy of 5-chloro-3-methyl-4-nitro-1H-pyrazole (CMNP) for loosening
Effects of Short-term Drought Stress and Mechanical Harvesting on Sweet Orange Tree Health, Water Uptake, and Yield
. One of the primary reasons for the slow adoption of mechanical harvesting by Florida citrus growers is the physical injuries associated with it, including loss of leaves, twigs,flowers, andyoung


Mechanical Harvesting Capacity in Sweet Orange Is Increased with an Abscission Agent
It is demonstrated that CMNP application increases harvesting capacity of trunk and canopy shakers by reducing time necessary to harvest each tree while maintaining high percent mature fruit removal.

Mechanical Harvesting Has Little Effect on Water Status and Leaf Gas Exchange in Citrus Trees
Long-term studies revealed that fruit yield of citrus trees was affected little by mechanical harvesting, and mechanical harvesting did not reduce CO2 assimilation, transpiration, stomatal conductance, water use effiency, or photosystem II effi ciency as measured by chlorophyll fl uorescence.
Using Molecular Biology Tools to Identify Abscission Materials for Citrus
Two major objectives of the abscission research program at the Citrus Research and Education Center in Lake Alfred are to define changes that occur during the ab scission process in citrus fruit and leaves and translate this information into viable abscissions agents for the Florida citrus industry.
Trunk Shakers for Citrus Harvesting—Part I: Measured Trunk Shaker and Tree Trunk Motion
The motions of shaker and trunk were measured in 'Hamlin' and 'Valencia' oranges for two harvest seasons on linear and mulidirectional shaking patterns to study the effects of shaking patterns on fruit removal and trunk amplitude.
Guanfacine and Clonidine Reduce Defoliation and Phytotoxicity Associated with Abscission Agents
