Tropical Fruit

In southern Florida, most tropical fruit crops between Biscayne and Everglades National Parks are irrigated at rates and frequencies based on experience and observations of tree growth and fruit yield rather than on reliable quantitative information of actual water use. This approach suggests that irrigation rates may be excessive and could lead to leaching of agricultural chemicals into the groundwater in this environmentally sensitive area. Therefore, a study is being conducted to increase water use efficiency and optimize irrigation by accurately scheduling irrigation using a very effective management tool (EnviroScan, Sentek Environmental Innovations, Pty., Kent, Australia) that continuously monitors soil water content with highly accurate capacitance multi-sensor probes installed at several depths within the soil profile. The system measures crop water use by monitoring soil water depletion rates and allows the maintenance of soil water content within the optimum range (below field capacity and well above the onset of plant water stress). The study is being conducted in growers' orchards with three tropical fruit crops (avocado, carambola, and `Tahiti' lime) to facilitate rapid adoption and utilization of research results.

In tropical fruit crops, anthracnose is mainly caused by species belonging to the fungal genus, Colletotrichum. These phytopathogens can infect several parts of the fruit crops; however, infection during postharvest or ripening stages is responsible for major economic losses. Due to the formation of black to dark brown sunken lesions on the fruit surface, anthracnose reduces fruit quality and marketability. Among the most common tropical fruit crops susceptible to anthracnose are mango, papaya, banana, avocado, guava, and dragon fruit; these are economically relevant products in many developing countries. It is important to document that the newly recorded Colletotrichum spp. associated with fruit anthracnose can infect multiple hosts, but some species may be host-specific. By using multiple markers, many phylogenetic species of Colletotrichum have been reported as anthracnose-causing pathogens. Taking into account that disease management strategies strongly rely on adequate knowledge of the causative agents, updated information on Colletotrichum species and the hazard posed by the most recently identified species in tropical fruit plantations and harvested fruits becomes vital. Besides, the newly recorded species may be important for biosecurity and should be listed as quarantine pathogens, considering that tropical fruits are traded worldwide.

Background: Salak is one of Indonesia's native tropical fruit crops and is one of the interesting commodities to be developed to meet domestic and export needs. Salak can be processed foods such as salak jam. Method: This research was conducted on March 8-16, 2016. This research use descriptive research type. The parameters measured and observed are the color, texture, taste, and level of fondness. Results: The results showed that the higher the sugar addition, the higher the organoleptic value, the highest degree of the sensitivity to the color, texture, and taste was on the 100 gram sugar treatment and the lowest on the 0 gram sugar treatment. Conclusion: Based on the results of the study can be concluded that the addition of sugar has an effect on organoleptic quality of fruit jam.

New Pest

The IR4 Specialty Crops Program was established to assist in the registration of pest control products for minor uses. The national program, headquartered at Rutgers University and operating through four regions with a network of scientists in every state develops lists of grower needs, prioritizes projects and develops protocols to secure EPA tolerances that lead to labels. Every year IR4 works on pest control products needed by the fruit industry. Pest control products being researched for 2006 include: Insect and disease control in tropical fruit crops: Lepadopterous larvae control in peaches with Avaunt, Danitol, and Spintor: Mite and raspberry crown borer control in blackberry: Weed control in blueberry with Sandea and Spartan: Botrytis and anthracnose control in strawberry.
