“…Differences were observed in the rates of infection over the 6 month period with respect to the treatments. Calcium nutrition has been linked to the resistance of many plant species to fungal and bacterial diseases (Muchovej et al 1980;Yamazaki et al 1999;Sugimoto et al 2005). Calcium plays a key role in development of plant cell walls (Epstein 1972;Mengel et al 2001) and studies suggest that disease severity is reduced due to increased Ca concentrations in cell walls (Muchovej et al 1980;Conway et al 1992;Sugimoto 2005).…”

“…For example, calcium applications have been shown to reduce the impacts of fungal disease on soybeans (Glycine max (L.) Merr.) and bacterial wilt on tomato (Lycopersicon esculentum L.) seedlings (Muchovej et al 1980;Sugimoto et al 2005;Yamazaki et al 1999). Other cations, particularly potassium (K) and magnesium (Mg), have also been linked to disease resistance in plants.…”

“…Calcium strengthens plant cell walls, which may help in disease resistance (Muchovej et al 1980;Conway et al 1992;Sugimoto 2005). Potassium and Mg are essential for many plant metabolic functions (Epstein 1972;Mengel et al 2001).…”

Influence of calcium, potassium, and magnesium on Cornus florida L. density and resistance to dogwood anthracnose

Dogwood anthracnose, a major disease of Cornus florida L., has caused heavy mortality of C. florida in eastern United States forests. Disease severity and rate of infection have been shown to vary with several environmental factors, but the link between soil cation availability and anthracnose has not been examined. We hypothesized that soil cation availability, particularly calcium (Ca), potassium (K), and magnesium (Mg), would influence dogwood survival from anthracnose. In forested stands, positive correlations between soil Ca, K, and Mg saturation and C. florida stem density and basal area were found. The effect of these cations at four levels (0, 50, 100, and 200%) of a standard nursery fertilization rate on C. florida seedling survival and resistance to dogwood anthracnose was tested. Although most of the seedlings died after one season of exposure to dogwood anthracnose, seedlings that had lower inputs of Ca and K cations showed higher levels of disease severity sooner than seedlings in other treatments, suggesting that these nutrients play a role in C. florida survival from anthracnose. Magnesium treatment levels did not appear to have an effect on C. florida disease severity or mortality.

“…Calcium sulphate + magnesium sulphate treated palms reduced the positive reaction in ELISA, but Ganoderma infection was detected in the PCR test; this treatment may thus take a few more months to give complete control. The reason for the reduction in disease intensity was attributed to strengthening the cell wall by calcium and thus enhancing resistance to Ganoderma attack (MUCHOREJ et al 1980;SPIEGEL et al 1987). KOMMEDAHL and WINDELS (1981) suggested another reason for the reduction in disease severity by calcium application.…”

Molecular and immunological methods were applied for detecting the Ganoderma disease of coconut. Polyclonal antibodies (PAbs) raised against basidiocarp protein of Ganoderma were used. For the polymerase chain reaction (PCR) tests, the primer generated from the internal transcribed spacer region one (ITS 1) of ribosomal DNA gene of Ganoderma, which produced a PCR product of 167 bp in size, was used. Apparently healthy palms in two coconut gardens were tested for Ganoderma disease by ELISA test using basidiocarp protein antiserum. Field trials were laid out in these early-diagnosed palms for the management of the disease. Based on the ELISA results, Pseudomonas fluorescens + Trichoderma viride with chitin amended treatments arrested the multiplication of the pathogen and within 6 months showed an optical density (OD) below the level of infected plants. Integrated Disease Management (IDM) and fungicide tridemorph treated palms showed OD values below infection level within 7 months, and T. harzianum and P. fluorescens + T. viride treated palms showed OD values below infection level in 8 months.

“…Increased calcium content in plant tissues inhibits development of some diseases. Fertilizing with calcium reduced Fusarium wih of tomato (CORDEN 1965) and muskmelon (SPIEGEL et al 1987) and also the susceptibility of bean hypocotyls to Rhizoctonia solani (BATEMAN and LUMSDEN 1965) and of soybean to Colletotrichum dematium (MUCHOVEJ et al 1980). Liming of low calcic soils caused a reduction of tomato grey mould incidence (STALL 1963).…”

Fertilization of bean plants grown in perlite with 1 and 3 mM CaCl2 or Ca(NO3)2 reduced severity of grey mould as compared with control plants or plants fertilized with 5 mM of the compounds. Fertilization with Ca(NO3)2 reduced severity leaf grey mould and fruit ghost spots of tomato plants grown in perlite by 70 and 45%, respectively. The rate of decrease varied with the position of the fruits on the plants. Leaves from plants treated with calcium or otherwise [KNO3, (NH4)2SO4] produced less ethylene than leaves of nontreated plants. Rate of growth of B. cinerea was lower on growth medium prepared from washings from leaves of calcium fertilized plants than from leaves from other treatments. The fertilizer combination Ca(H2PO4)2+ CaSO4 (1 and 3 g/kg soil) applied once to tomato plants grown in soil reduced severity of leaf grey mould by 80 % (significant at P = 0.05) but 1–3 g CaSO4/kg soil only tended to reduce disease severity (30–40 %, not significant) as compared with the control. The compounds CaCl2 and Ca(NO3)2 increased significantly (P = 0.05) the growth of B. cinerea on synthetic medium when applied at rates of 1 0–10.0 mM whereas reduction of growth was observed with 0.1 mM of the compounds and of CaSO4.
