Fungicide Application Timing Essential for the Management of Leaf Spot and Fruit Rot on Pomegranate (Punica granatum L.) in Florida For resistance management, treated culled fruit should not be returned to pomegranate orchards or other fruit crops orchards where fludioxonil is applied postharvest. Management of guava diseases Wilt An intergated approach using Aspergillius niger strain AN17 and resistant root stock ( P.molle x P.guajava) Intercropping with marigold or turmeric Anthracnose Carbendazim-mancozeb combination (2g/l) Canker and Phytophthora fruit rot Bordeaux mixture (1%) Damping off Raised beds Drench copper oxychloride In Sri Lanka, there are several fungus diseases which are economically important in pomegranate cultivation and are detailed below as follows: Anthracnose fruit rot caused by Sphaceloma punica, Aspergillious fruit rot caused by Aspergillus sp. Fruit: Pomegranate Disease: Fungal Pathogen: Phytophthora sp. Spraying 2 grams per litre mancozeb during monsoon would take care of leaf spot. Fruit rot: Phytophthora spp., Aspergillus foetidus Thom & Raper; IPM for Pomegranate. Abstract. The fruit surface starts to turn brown, with the rot progressing into the rinds and to the arils. Spots on fruits are brown to dark brown, first circular, then irregular as they expand. Pomegranates (Punica granatum L.) include more than 500 known cultivars and produce medium-sized, leathery fruits … has previously been reported in USA, Mexico (Farr et al., 2007), and as a postharvest disease in Greece (Pantidou, 1973). Leaf spot and fruit rot are the main diseases affecting pomegranate crops. Commonly called black spot and fruit heart rot, they are often dependent on the variety of pomegranate. Alternaria fruit rot infections commonly begin in the orchard following rain during flowering and early fruit development. © 1996–2020 Statewide IPM Program, Agriculture and Natural Resources, University of California Regents of the University of California unless otherwise noted. Not all registered pesticides are listed. Fruit rot management. production in Florida. Petrak and Sydow, and the disease has resulted in substantial losses and is threatening the upcoming pomegranate cultivation in Himachal Pradesh. Pomegranate (Punica granatum) is a rapidly developing crop grown for its fruits all over Greece.In autumn 2006 a fruit rot was observed in six pomegranate orchards in the area of Serres (Northern Greece, Central Macedonia). Harvesting Pomegranate. Sharma, R.K. Tegta: Keywords: Coniella granati, management, plant extracts, pomegranate, pre-harvest: DOI: 10.17660/ActaHortic.2011.890.69: Abstract: Pomegranate is highly susceptible to dry fruit rot caused by Coniella granati (Sacc.) (Lepidoptera: Noctuidae) Diseases. Decay can also start from the stem end wound, especially if the stem is entirely removed. COMMENTS: A chitin biosynthesis inhibitor, which has medium resistance potential. In addition to fruit rots caused by Colletotrichum spp. 48 Fruit rot: 1. All the affected fruits should be collected and destroyed. Anthracnose also can attack twigs and branches and results in cankers, which are … Alternaria fruit rot – Alternaria is also called black rot and causes damage to the fruit in the form of wounds and rot on the interior of the fruit. If storing for longer than three months, a controlled atmosphere of 5% oxygen plus 15% carbon dioxide is suggested. Use good orchard management practices, such as dust control and sanitation (removal of old fruit and dead branches), to reduce the incidence of the disease. Crown rot decay caused by the gray mold Botrytis cinerea and Penicillium sp. In 2010, the fi rst report on black spot disease of pomegranate caused by A. alternata on pomegranates in Israel has been published as a new disease. One or two mealybugs on a fruit are not serious, but when many cluster in the flower ends, or between fruit, they may lead to rot. and D. punicae, a third fungal pathogen, Pilidiella granati, is often isolated from rotten fruit. Fruit Rot and Mummification Fruit rot is a serious problem of pomegranate and can result in more than 80% fruit loss in Florida. Aspergillus fruit rot – Aspergillus has similar timing and effects as Alternaria fungal issues. The fruit later softens and rot develops in the arils which turn dark gray or black but are not watery. The pathogen sporulates on the flower parts and the typical grayish coating of spores develops. Botrytis spores reside in or on the soil and on previously infected plant tissue, weeds, and old fruit left on the tree or on the orchard floor (mummies). Application of 2 grams per litre Kavach during September and October months would prevent fruit rot. They do not produce a lot of wet honeydew. Infected fruit generally are lighter in weight and the rind may be slightly off-color, such as a paler red, and may show some brownish-red discoloration. Decay develops quickly when shelf temperature is about 65° to 75°F (18°–24°C). Abstract Shoot dieback and necrotic black lesions were observed on pomegranate trees ( Punica granatum ) in commercial orchards in South Africa near Ladismith and Malmesbury in 2011. Literature on pomegranates in California is not extensive. Exploring new methods to reduce dependency on use of agrochemicals is a worldwide trend. M.sc (Agri) thesis, Uni. Eventually the crown tissue will be colonized, and the fungus will grow into the fruit tissue. diseases of pomegranate fruit (Michailides et al., 2012). Sci. Petrak and Sydow, and the disease has resulted in substantial losses and is threatening the upcoming pomegranate cultivation in Himachal Pradesh. (See photograph of similar rind rot in aphid section.) At maturity, the fruits turn yellowish-red and get suppressed on sides. Corpus ID: 86235102. The optimal postharvest storage temperature for pomegranates is 41°F (5°C) for up to two months and 45°F (7°C) for longer than two months. and Aspergillus sp. (2012) explained that, Black heart, which has also known as “heart rot”, is a major pomegranate disease impacting production in California. and Cercospora sp. and Penicillium fruit rot caused by Penicillium sp. Gray mold is one of the most important causes of postharvest decay in pomegranates. In addition to fruit rots caused by Colletotrichum spp. Symptoms first appeared as small circular spots on the fruits which later increased in size and developed into expanded brown lesions. In advanced stages of internal decay, the fruit's exterior shows some shriveling. Estimated losses are usually less than 1% but can be up to 6%. The fungus may grow inside the fruit without external symptoms, but external decay symptoms are more commonly seen with Aspergillus fruit rot than with Alternaria fruit rot.
