stylar end rot of guava treatment. Guava diseases are among the most important factors in guava production or farming, which cause a major loss in guava fruit yield and vigor. Rev. The objective of this study was to identify the primary species of Botryosphaeriaceae that cause guava stylar-end rot and to evaluate the temperature and wetness. The stylar is the end of the fruit that we usually call the naval. When the stylar is cracked or damaged, an infection can get in that causes the damage and rot. Stylar end breakdown causes include a few different pathogens of Alternaria citri. Unhealthy or damaged fruit is susceptible to the infection. The infection may occur while the fruit. The paper deals with investigations on the stylar end rot of guava fruits. Fruits in the orchard as well as in storage suffer with this disease, which is, however, of rare occurrence. The symptoms of the disease have been described in detail. A species ofPhomopsis was constantly associated with this rot and later pathogenicity tests proved this fungus to be the causal organism

Cross of Psidium mallex P. guajava has been found free from wilt and this material can be used as resistant root stock.  Eco-friendly approach of guava wilt control is suggested where biological control, soil amendment and intercropping are effective.  Biological control by Aspergillus niger strain AN-17 is found effective Stylar end rot - spraying 0.3% of copper oxychloride with a 15 day interval. Wilt - supplying FYM mixed with Aspergillus Niger strain AN17 @ 5 kg/pit. Guava rust - controlled by spraying 0.1% of Bordeaux mixture.

  1. Guava wilt. Disease symptoms: First symptoms start with the onset of monsoon. Appearance of light yellow foliage with loss of turgidity and epinasty. Plants, at a later stage, show unthriftyness. Subsequently, premature shedding and defoliation. Some of the twigs become bare and fail to bring forth new leaves or flowers and eventually dry up
  2. Stylar-end breakdown is a common disorder of 'Tahiti' lime that is exacerbated by increasing temperatures but it can also be induced by postharvest hot water treatments or exposure to the sun before or after harvest (Davenport and Campbell, 1977)
  3. Stylar-end breakdown can be a significant problem with lemons. Stylar-end breakdown begins as an apparent breakdown of tissues at the stylar end of the fruit. Typically the stylar-end takes on a wet appearance. Large, mature fruit are more susceptible. The incidence of the disorder can be aggravated by high field heat and rough handling
  4. For instance, 1-MCP treatment has been reported to reduce the decay incidence in guava fruit (Singh and Pal, 2008b). Similarly, exposure of mature unripe guava fruit to gamma irradiation (0.25-0.5 kGy) has potential to reduce fruit decay (Singh and Pal, 2009). Maximizing storage life of most tropical fruits requires treatment with a fungicide
  5. Stylar-end breakdown (stylar end rot) More of a concern with 'Tahiti' lime than Key lime, stylar-end breakdown appears as a breakdown of tissues at the stylar ends of fruit. It eventually causes decay of the entire fruit (Browning et al. 1995; Davenport et al. 1976)

Characterization of the guava farms-This study considered five guava varieties (see Table 5): Paluma, Pedro Sato, Século 21, Tailandesa and Cascão.

The vitamin C contents of guava fruit are four times higher than those of citrus. The leaves of guava have been used for curing diarrhoea and dysentery Thus, guava crop is known to be suffering from various fungal diseases, i.e. seed rot, anthracnose, Cercospora spot, stylar end rot, wilt and sooty mould (Younis et al., 2004; Ismail et al., 2010 and Dwivedi and Neetu, 2012). Fruit drop disease is one of the major problems on guava crop, when leads to substantial loss in guava yield production dihydrate (ethanol+chlorine)] and hot water treatment, singly and in combination of two treatments, on the occurrence of stylar-end rot and on the skin color and pulp firmness characteristics of 'Pedro Sato' guava. The treatments were evaluated in naturally infected guavas at three maturity stages and stored at 22ºC for 8 days In Kensington and Mulgoa fruit, mesocarp at the stylar end of the fruit was softer than at the pedicel end. In all cultivars, the inner mesocarp had significantly higher total soluble solids and pH, and a lower titratable acidity than the outer mesocarp In Navel oranges, fungal conidia may be located at the stylar end. Alternaria black rot of citrus may occur in the field before harvest. The disease is a common problem in Mediterranean climates due to cool, moist winters and hot dry summers [21]

anthracnose, styler-end rot and stem-end rot are some of the primary factors responsible for fruit drop. Application of 2,4-D 10ppm combined with aureofungin 20ppm in the first week of September provides excellent check against physiological and pathological pre-harvest fruit drop in citrus Guava fruit borers/ pomegranate butterfly. Biology: Eggs: Eggs are laid singly on tender leaves, stalks and flower buds. Larvae - Dark brown, short and stout, covered with short hairs, larval period lasts for 18-47 days. Pupa: Development occurs either inside the damaged fruits or on the stalk holding it. Pupal period lasts for 7-34 days Diachasmimorpha longicaudata or Opius longicaudatus var. malaiaensis (Fullaway), O. vandenboschi (Fullaway), and O. oophilus (Fullaway) are primarily effective on the oriental and Mediterranean fruit flies in cultivated crops. O. longicaudatus is a parasite of the second and third instar fruit fly larvae; O. vandenboschi is a parasite of the first instar fruit larvae; and O. oophilus is an egg. some treatments: 1- control (sprayed with water only). 2- Calcium chloride at 1%. 3- Calcium nitrate at 0.6%. 4- Paclobutrazol at 150 ppm.
