Opis:: Silicon (Si) is the second most abundant element present in the lithosphere, and it constitutes one of the major inorganic nutrient elements of many plants. Although Si is a nonessential nutrient element, its beneficial role in stimulating the growth and development of many plant species has been generally recognized. Silicon is known to effectively reduce disease severity in many plant pathosystems. The key mechanisms of Si-mediated increased plant disease resistance involve improving mechanical properties of cell walls, activating multiple signaling pathways leading to the expression of defense responsive genes and producing antimicrobial compounds. This article highlights the importance and applicability of Si fertilizers in integrated disease management for crops.

Opis:: In the years 1993-1995 experiments on integrated pest management (IPM) were conducted. A three year experiment with winter wheat was performed to evaluate the effect of chemical control of diseases on their occurrence and grain yield, at various conditions of N fertilisation. The economical profit was analysed.
W latach 1993-1995 podjęto doświadczenia dotyczące stosowania Integrowanych Metod Ochrony Roślin (IPM). Doświadczenia przeprowadzono na pszenicy ozimej, oceniano efekt zwalczania chorób po zastosowaniu fungicydów przy różnych poziomach nawożenia azotowego. Nawożenia azotowe ustalono na poziomie dawki standardowej - zgodnie z analizą chemiczną. Określono efekt ekonomiczny i stwierdzono, że przy niskim porażeniu pszenicy przez choroby największy wpływ na plon miały wzrastające dawki azotu. Zastosowanie fungicydów było ekonomicznie uzasadnione tylko przy najniższym poziomie nawożenia N w warunkach niskiego porażenia pszenicy ozimej.

Opis:: Potato virus Y (PVY) is one of the most destructive viruses infecting potato in Egypt and worldwide. Recent research has shown that a necrotic PVY-NTN strain is infecting potato in Upper Egypt. Chemical control is not effective to control this viral pathogen. An alternative to control PVY infecting potato is using a mild PVY strain to elicit systemic cross protection in potato plants against infection with a severe necrotic strain of PVY. Results of this study showed that a PVY necrotic strain produced a significant lesser number of local lesions on diagnostic plants (Robinia pseudoacacia L.) when these plants were treated first with a mild PVY strain. Data obtained from greenhouse and field experiments indicated that treatment of potato plants (variety Burna) with a mild PVY strain significantly protected potato from infection with a severe necrotic PVY strain, and resulted in a significant increase in tuber yield compared with infected plants without prior treatment with a mild PVY strain. The highest increase in potato tuber yield was obtained when potato plants were inoculated with a mild PVY strain 3 days before challenging with the severe necrotic PVY strain. This study proved that using a mild strain of PVY can significantly protect potato plants from infection with a severe strain of this virus under both greenhouse and field conditions and can present a potential method to reduce losses due to infection of this virus in Assiut governorate and Upper Egypt.
