Foliar spraying Fe-EDTA reduced powdery mildew of tomato plants ( Bakeer et al., 2012). Micronutrient iron also has could alter disease severity in tomato plants. radicis-lycopersici, but the zinc improved biocontrol activity by Pseudomonas fluorescens ( Duffy and Dé fago, 1997). Interestingly, zinc (Zn-EDTA)-amended hydroponic nutrient solution alone could not reduce tomato Fusarium crown and root rot by F. Early blight in tomato plants inoculated with Alternaria solani was ameliorated by ZnSO 4 supplement ( Awan et al., 2019). Powdery mildew of tomato plants by a natural inoculation was suppressed by foliar spraying manganese (Mn-EDTA) and zinc (Zn-EDTA), each alone or in combination ( Bakeer et al., 2012). Increased MnSO 4 concentration in the nutrient solution reduced tomato black leaf mold caused by Pseudocercospora fuligena ( Heine et al., 2011). Boron levels in the nutrient solution was negatively correlated with tomato bacterial wilt severity ( Jiang et al., 2016). Micronutrients such as boron, manganese and zinc could also altered disease development of several tomato plants. Enhanced plant immunity, such as elevated H 2 O 2 levels and increased peroxidase and polyphenol oxidase activities, was involved in the CaCl 2-mediated suppression of tomato bacterial wilt ( Jiang et al., 2013). solanacearum in tomato plants ( Berry et al., 1988 Yamazaki and Hoshina, 1995). CaCl 2 supplement in nutrient solution decreased disease severity of bacterial canker by Clavibacter michiganense subsp. radicis-lycopersici infection, whilst nitrate-nitrogen ameliorated the disease severity ( Duffy and Dé fago, 1999). Interestingly, ammonium-nitrogen increased tomato crown and root rot by Fusarium oxysporum f. solanacearum, respectively ( Ding et al., 2021). However, increasing nitrate and ammonium nitrogen nutrition led to increased disease susceptibility of tomato plants to bacterial speck and bacterial wilt caused by Pseudomonas syringae pv. Foliar application of potassium nitrate (KNO 3) reduced lesion size on Alternaria solani-inoculated tomato leaves ( Blachinski et al., 1996).

However, it is still necessary to investigate how to integrate different controlling methods into eco-friendly pest management programs during tomato production.Ĭhanges in plant nutrient conditions have affected the disease severities of various crops such as tomato plants ( Dordas, 2008 Tripathi et al., 2022). Bacterial and fungal species originating from a diverse plant rhizosphere also ameliorated bacterial wilt by enhancing plant immunity in tomato plants ( Jogaiah et al., 2013 Kurabachew and Wydra, 2013 Tan et al., 2013). The tomato bacterial wilt was efficiently reduced by various chemical treatments: copper-associated pesticides, streptomycin-validamycin A antibiotics mixture, combined hydrogen peroxide-nitric oxide, plant essential oils such as clove oil and palmarosa oil ( Hong et al., 2013 Lee et al., 2012 Pradhanang et al., 2003). Chemical and biological controls have been suggested for managing the tomato bacterial wilt. Bacterial wilt of tomato plants has been known as a devastating soil-borne disease caused by Ralstonia solanacearum species complex, and this bacterium invades roots and colonises vascular tissues of a broad range of economically important crops, including peanut, potato and geranium ( Choi et al., 2022 Muthoni et al., 2014 Swanson et al., 2005).
