If squash has been exposed to chilling injury it should be marketed first and not selected for long-term storage. Remove squash from the field if temperatures likely to drop below fifty degrees for any length of time. After curing, move squash or pumpkins to a dry, well-ventilated storage area. Pressure bruises can also reduce storage life, so avoid rough handling, tight packing, or piling fruit too high. Alternaria citri is an ascomycete fungal plant pathogen that causes black rot in citrus plants. Specifically, certain lemon, lime, orange, mandarin and grapefruit species are susceptible hosts for this : Pleosporaceae.
Alternaria alternata is the predominant fungus involved in moldy core and core rot of Red Delicious apples. The effects of environmental conditions during bloom on moldy core and core rot, and on the need for fungicide application, were examined in 10 experiments carried out in Alternaria species are common saprophytes or pathogens of a wide range of plants pre- and post-harvest. This review considers the relative importance of Alternaria species, their ecology, competitiveness, production of mycotoxins and the prevalence of the predominant mycotoxins in different food products. The available toxicity data on these toxins and the potential future impacts of Cited by:
Pumpkins and Winter Squash; Harvest mature fruit with hard rinds before frost. Leave the stem on when cutting from the plants to prevent decay organisms from entering. Pumpkins and winter squash will keep best if they are cured for 10 days at °F. Acorn squash, however, should not be cured but stored at 45°F to prevent stringiness.

The rot on musk-melon and cucumber fruit is often associated with sunscald injury or over-ripeness. DISEASE CYCLE The mycelium of Alternaria cucumerina is dark. InFile Size: KB. Chilling Sensitivity: Both pumpkins and Winter squashes develop chilling injury at inhibits yellowing, but causes sunken pits on the fruit.
Infection can occur through the flowers, or following insect injury, mechanical damage, chilling injury, sunburn, or blossom- end rot The black mold indicative of Alternaria fruit rot appears most often on mature red peppers either before or after harvest.
Red Chile peppers harvested during wet periods. Alternaria rot often develops by mid-season during cold storage of apples showing injuries such as delayed sunscald, bruising, or chemical injury. In apples held late in storage, the rot may develop at skin checks, as in the ‘York Imperial’ variety, or even at enlarged, ruptured lenticels over by: the spots become covered with a dark olive to black mold, the spores (conidia) of the Alternaria fungus (Figure 4).
Affected fruit may rot. On summer squash, rot starts at the blossom end. Fruit turn brown and shrink, later becoming black and mummified. The rot on muskmelon and cucumber fruit is often associated with sunscald injury or Size: KB. Alternaria radicina is seedborne and may be spread on carrot seed.
It also survives in carrot debris and in the soil for several years. Black rot is important only in certain areas or regions in California. It is common in coastal mountain valleys, e.g., the Cuyama Valley. MANAGEMENT Cultural Control.

Fruit infected with Alternaria change color prematurely. The decay is softer on lemons. Once a crop is harvested, it is almost impossible to improve its quality.
Losses of horticultural crops due to improper storage and handling can range from 10 to 40 percent. Proper storage conditions—temperature and humidity—are needed to lengthen storage life and maintain quality once the crop has been cooled to the optimum storage temperature.
The severity of chilling injury in zucchini squash stored at 5°C and then transferred to 20°C was reduced by a prestorage treatment with hot water of 42°C for 30 min. The chilling injury was further reduced when zucchini squash were preconditioned at 15°C for 2 days after hot water treatment but before the 5°C by: Alternaria rot following chilling injury of acorn squashes.

Black rot, Although chilling injury may not be visible during storage at lower temperatures, the symptoms appear later after warming (usually during transit) as sunken pits in the surface where tissue has been weakened or killed by cold.
Basic requirements Squash is a warm-season crop, requiring lots of sun and good drainage to develop optimally and growing best at temperatures between 18 and 25°C (65–75°F).
Squash will yield best if grown in a fertile, well-draining soil, rich in organic matter and with a pH between and Squash should be planted in full sun and provided with ample soil moisture due to their.

The effects of chilling injury are cumulative in some crops. Low temperatures in transit, or even in the field shortly before harvest, add to the total effects of chilling that might occur in storage (7).
Crops such as basil, cucumbers, eggplants, pumpkins, summer squash, okra, and sweet potatoes are highly sensitive to chilling injury. The following management practices will help you care for your lawn throughout the year. Location, terrain, soil type and condition, age of the lawn, previous lawn care, and other factors affect turf performance, so adjust these management practices and dates to suit your particular lawn.
