AbstractIrrigation water is produced within the irrigation subprocess of a farm. Water supply is identified for effective field water, which sets the upper bound on water available for plant use. Georgescu-Roegen process analysis concepts are merged with the neoclassical theory of cost as the underlying framework. The approach is illustrated for a permanent overhead system used in a Florida citrus grove. The marginal cost for the 2.54 centimeters application depth dominates all other depths for the higher water levels. Process analysis is an important analytical tool for increasing understanding of the features of irrigation water supply.

Population density of citrus leafminer, Phyllocnistis citrella Stainton (Lepidoptera: Gracillariidae), was monitored in a Florida citrus grove for 5 years by scouting weekly for larval-induced mines (leafminer-created tunnels in the leaves) in a replicated citrus plot treated with seven insect control regimes: Admire (imidacloprid) applied at 12, 6, 3, or 2-month intervals; Temik (aldicarb) applied annually; Metasystox-R (oxydemeton-methyl) applied annually; or no insect control. Leafminer populations were highest during the warmer months (April to September) and lowest during the cooler months (November to March). Populations peaked during June in all 5 years monitored. Trees treated with Temik or Metasystox-R had the same number of mines as the untreated controls. A biannual treatment with Admire reduced leafminer damage (number of mines) all 5 years compared with the controls. Additional Admire applications further reduced damage during some, but not all, years. A single application of Admire significantly reduced mines in 3 of the 5 years.

Florida Citrus

Florida citrus (Citrus spp.) producers must improve water and nutrient use efficiency to remain sustainable as they face increasing urbanization, plant disease, and environmental awareness. Producers have traditionally used water-soluble nitrogen (N) and phosphorus fertilizer sources with calendar-based irrigation, but they are slowly integrating enhanced efficiency fertilizers into nutrient management plans and converting to sensor or evapotranspiration-based irrigation scheduling. Recent research has improved the understanding of the citrus grove N budget, which has led to development of appropriate best management practices (BMPs) that will maintain production while protecting the environment. BMPs that have been shown to decrease N loss to groundwater include applying the appropriate fertilizer rate, splitting fertilizer applications, converting to fertigation, and improving irrigation scheduling.

Orange Trees

An 8-ha block of 9-year-old Valencia orange trees, surrounded on three sides by drainage ditches, was divided into four equal-sized plots. A 4-m deep sampling well was drilled in the middle of each plot and a short piece of perforated pipe was placed above the water level in the bank of one of the drainage ditches to intercept seepage water. Water from the well in the third plot and the corresponding seepage pipe contained consistently NO3-N in the 20-ppm range, in contrast to the other sampling points, ranging from 0.1 to 9 ppm. Electrical conductivity was higher in plots 3 and 4, downstream from plots 1 and 2, in the ground water flow. Sodium in the water followed the same pattern P and K were the same, and pH was higher in plots 1 and 2 than in 3 and 4. Soil pH (5.2–5.8) and water-extractable NO3-N showed no patterns, organic matter (0.79% to 0.12%) and soil moisture (5.5% to 6.3%) were higher in plots 3 and 4. Leaf nitrogen (2.60% to 2.90%) was highest in the high-nitrate plot 3. The soil on the east side of this plot showed a higher nitrate-holding capacity compared to the other plots in an anion-exchange capacity procedure.

Insecticide Control

Asian citrus psyllid, Diaphorina citri Kuwayama, populations were monitored in a ‘Valencia’ sweet orange on sour orange rootstock plot planted in 1997. The plot was scouted weekly and the number of psyllids, percent trees infested, and the percentage of flush infested per tree were recorded over a 3-year period. The plot was treated with 7 insect control treatments: Admire (imidacloprid) applied at 12-, 6-, 3-, or 2-month intervals; Temik applied annually; Meta-Systox R applied annually; or no insecticide control using a randomized complete block design. Psyllid infestations persisted throughout the year. The lowest populations occurred during the winter (November-January) with peaks in the spring and fall. Annual applications of Temik, Meta-Systox R, or Admire did not reduce psyllid populations. Biannual or more frequent applications of Admire significantly reduced psyllid numbers, percentage of trees with psyllid infestations, and the percentage of flushes infested with psyllids.

Heavy Infestation

In Florida, clustered pellitory is becoming a troublesome weed for citrus, especially from the winter through early summer. Inadequate management of this weed can result in its heavy infestation in tree rows and can interrupt the spray pattern of low-volume drip irrigation systems. This new 3-page publication of the UF/IFAS Horticultural Sciences Department will assist Florida citrus growers with proper identification of clustered pellitory and with adoption of adequate and timely strategies to manage this weed in their groves.
