Strawberry diseases can cause damage to flowers, fruit, leaves, and in some cases, collapse of the entire plant leading to severe economic losses. Strawberry (Fragaria ananassa Duchesne; family, Rosaceae) is a commercially important fruit crop [1]. See current recommendations for chemical control of this disease. During the last decades, the use of both pesticides and chemical fertilizers has represented a serious risk for human health and brought disorder of ecosystem equilibrium. Fungal pathogens can attack the crop in all cultivation systems and can cause strawberry fruit decay in post-harvest. Winter damage and poor cultural management predispose strawberry plants to diseases. vescareference genome.Fw1and 11 tightly linked GWAS-significant SNPs mapped to linkage group 2C in octoploid segregating populations. Powdery mildew infection reduced the number of operational taxonomic units (OTUs) and prokaryotic and fungal community richness/diversity indexes in the rhizosphere soils compared with those in healthy plant soils. It first establishes itself on a plant part that is weakened, damaged, dying, or older vegetation, especially on the dying petals of older flowers. However, the recent EU restriction on synthetic pesticides made the management of fungal plant pathogens difficult and greatly stimulated the research of alternative solutions to chemicals. In particular, for strawberry, the management of a number of serious diseases in open field and greenhouse in soil or soilless cultivation has become difficult due to recent restrictions in agrochemical use and the lack of effective alternatives. The results suggested that powdery mildew-infected strawberry fruits and plants cannot be consumed. Many important diseases that impact strawberry yield thrive in the cool, coastal environment of the major production areas in California. Aphids (greenfly) are sometimes troublesome; they can be checked by spraying with a nicotine and soft soap solution. Results showed that irradiated plants had a lower rates in comparison to the control plants for most of the studied characteristics, except for number of leaves, fruit sugar and anthocyanin. This fungal infection has the same symptoms as another fungal disease of strawberries, Fusarium wilt. The Cooperative Extension System does not guarantee or warrant the standard of any product referenced or imply approval of the product to the exclusion of others which also may be available. Consequently, algae for their biostimulant and antifungal effects may be considered useful tools to reduce the input of chemicals in integrated pest management strategies.

Extreme events, policy response and social action, Dr Husaini, Centre for Plant Biotechnology, Sher, Horticulture and Forestry, Solan, India. Strawberry is a delicious fruit with a special economic position in the fruit industry, because of its post-harvest processing and antioxidant functional value. A healthy fruit that is touching an infected fruit can become infected by the fungus growing directly from one to the other. Strawberry plants can fall victim to a number of diseases, especially when subjected to stress. Therefore, gamma ray intensity in the recommended limit could be used for the highest genetic diversity creation with the lowest plant mortality in strawberry breeding programs such as in fruit quality improvement.

Climate change and forecasting the impact on strawberry, 14.2. 2014;Koike and Gordon 2015; ... Several strawberry cultivars have been identified as resistant or susceptible to Fusarium wilt in previous studies conducted using a variety of screening protocols, pathogen isolates, and environments (Takahashi et al. A crop rotation of two to three years can be helpful in controlling this disease, as the fungus overwinters in plants and debris in the soil. Moreover, multifoliate and dwarfism were increased in the irradiated plants. Some varieties are less susceptible, but none are completely resistant. The leaf spot fungus produces microscopic spores from three different sources that infect new leaves in the spring. 2004;Takahashi et al. ,b, 2013Paynter et al. Lastly. He has several awards such as the CREST, biography was included in 27th edition of the Marquis Who’s Who. Microascus, Talaromyces, Zopfiella, and Cryptococcus were relatively more abundant in the powdery mildew-infected strawberry plant rhizosphere soils. tional, molecular and participatory plant breeding. It then can grow into the healthy parts of the plant, such as the fruit being produced from the flower with the dying petals. Since long time, algae are used in agriculture as soil amendment for their beneficial effects on plant health and productivity.

Pathogen incidence in strawberry production, 10.2. fragariae (Takahashi et al. See current recommendations for chemical control of this disease. The Main Breeding Programmes and Released Cultivars W, 4.2. The most famous and frequent diseases of strawberry garden are: rot: white, gray, black, root and late blight; powdery mildew; fusarium bushes; spotting: white, brown and black. The research for sustainable crop production is mandatory to face climate change and reduction of genetic biodiversity and soil fertility in farming systems and to increase food security, food safety and ecosystem services. 2002) requiring several fungicidal treatments (Romero et al. The fungus, Phytophthora cactorum, is in the soil, and can infect fruit after being splashed onto it by rain or by the fruit being in direct contact with the soil. Other molecular techniques used to study fungal pathogens, 10.3.6. Proteomics advances in strawberry fungal pathogens, 11.2. On immature fruit, brown to dark brown spots that remain firm appear. Professors Farooq A. Zaki and Riaz A. Shah for their support and encouragement. Quercetin, a avonoid contained in them, has been shown to reduce, the risk of atherosclerosis and to provide protection against the damage caused by, low-density lipoprotein cholesterol. dedicated exclusively to the subject of the strawberry. University of Massachusetts Cooperative Extension System. 1998. Picking and packing are also more costly when these diseases are present in the field. A neutral effect of tunnels was present for Lygus lineolaris density and weed biomass during both years, although damage by L. lineolaris decreased under UV-limiting plastics. 2012. These are of, medicinal importance. Schmeda-Hirschmann, G., Viveros-Valdez, E., Montenegro, R., Quispe, C., Simirgiotis, M.
