“…On the other hand, one pathogen could be inhibited by various salts. These results are consistent with many other reports [17,27,[70][71][72]. In fact, these salts possess wide-spectrum antimicrobial properties and have been demonstrated to inhibit the growth of several fungal pathogens infecting stored fruits, vegetables, and ornamental species [17,[19][20][21][22].…”

“…Other inorganic products, as alternatives to fungicides, include the fertiliser monopotassium phosphate that was tested on pepper. Reuveni et al (1998) claimed that it induced local and systemic resistance against L. taurica and was as effective as a sterol-inhibiting fungicide (DMI). Diop-Bruckler and Molot (1987) tested hyperparasites, with yeast as a nutrient, against L. taurica on tomato, but results obtained showed no differences between the fungi and the yeast (control).…”

The efficacy of Milsana Ò VP 1999 and 2000 (a formulated plant extract of Reynoutria sachalinensis), known to induce resistance to powdery mildew on cucumbers, was tested against Leveillula taurica (Le´v.) Arn. on greenhouse tomato. In four out of five trials, Milsana Ò achieved a disease reduction ranging from 42.2 to 64.6%. In one trial only, its efficacy was exceptionally low (23%). Application rates and disease pressure proved to be the main factors affecting the level of control. Milsana Ò was significantly less effective than fungicides (alternated DMIs and penconazole) in situ. In contrast, Milsana Ò was equally effective to wettable sulphur indicating that its effect was rather preventive than curative. The level of efficacy achieved by either Milsana Ò or fungicides did not result in a significant increase of yield. Laboratory tests showed that Milsana Ò (VP 1999) had a direct effect on conidial germination. Whether this effect significantly contributes to its field efficacy, remains to be elucidated. Overall, results indicate that Milsana Ò could play an important role in disease management of powdery mildew in organic and low input tomato production.

Plant analysis is an approved method to assess the nutrient status of crops. Diverging values for critical nutrient values for one crop species are related among others to growth stage, sampled plant part and interpretation method. This makes it difficult for scientists and farmers alike to decide on correct values. A metadata analysis of existing symptomatological, critical nutrient, no effect and toxicological values for phosphorus with respect to different crop plants has been carried out. Values have been clustered in different groups of crops based on morphogenetic and physiological characteristics and phosphorus concentrations have been agglomerated in three major categories: severely deficient, sufficient and toxic. A total P concentration of 0.175-0.25 % proved to denote severe P deficiency in all crops. Phosphorus contents between 0.30 and 0.34 % P indicate a sufficient P supply of graminoids, legumes and oil crops. Toxic effects may occur if the phosphorus content exceeds 1 % P. Factors which affect the phosphorus uptake of crop plants such as root architecture and features which are closely related to the phosphorus status, for example resistance against diseases are outlined.
