The five main methods to reduce strawberry leaf scorch include: irrigation techniques, crop rotation, planting resistant and disease-free seeds, fungicide use, and sanitation measures.

[1] Losses range from negligible to severe depending on numerous epidemiological factors including cultivar susceptibility, type of cropping system, and weather conditions [2] The host of Diplocarpon earliana is the strawberry plant.

The disease is characterized by numerous small, purplish to brownish lesions (from 1/16 to 3/16 of an inch in diameter) with undefined borders on the upper surface of the leaf.

The survival fruiting body structures, acervuli, can continue to develop in foliage beneath snow cover.

Conidia can escape from a small opening at the top of the acervulus and are dispersed mainly by splashing water or rain.

[citation needed] Optimal temperature for conidia production is between 20 and 25 degrees Celsius with free water present (commonly occurring during midsummer in many regions).

[6] Disease increase of Diplocarpon earliana is favored by long periods of leaf wetness (12 hours or more) between 15 and 25 degrees Celsius and frequent rain.

[7] The disease is prevalent in temperate, subtropical, and tropical regions because of the constant warm temperatures and heavy rainfall.

During early spring, infection may be most severe due to more precipitation creating adequate conditions for the development of this disease.

Lastly, burning the plant debris left after harvest decreases the amount of the D. earliana inoculum present in the subsequent season of production.

Crop rotation gives various nutrients a chance to accumulate in the soil, such as nitrogen, as well as the mitigation of pests or in the case of D. earliana, pathogens.

Since the rotated crop is not a host for D. earliana, the pathogen has a severely decreased chance of survival in structures such as endospores.

Some common crops in this rotation include corn and legumes, which can increase soil quality, suppress the strawberry leaf scorch pathogen, and reduce the amount of weeds.

Generally, an annual strawberry system will not need further disease management action and economic losses are not of heavy concern.

These fungicides are applied a variety of ways, at intervals ranging from one to two weeks when the strawberry plants are in early bloom.

[14] While the fruit of diseased plants are still edible, the market value decreases greatly because of consumer demand for the perfect, unblemished strawberry.
