One or two germ tubes are formed and act as a penetration tool. The fungus directly penetrates the host cell wall through enzymatic activity and turgor pressure. After the breakdown, the fungus develops a haustorium to supply it with nutrition.<\/p><p><strong>Powdery mildews reproduce both asexually and sexually.<\/strong> Asexual reproduction starts within a few days of infection. Conidiophores emerge from vegetative hyphae and conidia are produced serially. Conidia are then dispersed through wind over relatively short distances.<\/p><p>When the asexual growing season ends, sexual reproduction occurs via chasmothecia, which are small, round fruiting bodies containing asci, specialized sacs where ascospores are produced. As the nucleus from the male gametangia moves to the female gametangia through plasmogamy, it results in a dikaryotic cell, from which asci develop. The number of ascospores per ascus varies among the species from two to eight. Under favorable conditions, chasmothecia open and release ascospores.<\/p><p><strong>Powdery mildew fungi overwinter in several forms<\/strong> &#8211; chasmothecia, bud perennation, and mycelium become active again when favorable conditions return in the spring.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-5917d4d elementor-widget-divider--view-line elementor-widget elementor-widget-divider\" data-id=\"5917d4d\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"divider.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-divider\">\n\t\t\t<span class=\"elementor-divider-separator\">\n\t\t\t\t\t\t<\/span>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-b0f90b9 elementor-widget elementor-widget-spacer\" data-id=\"b0f90b9\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"spacer.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-spacer\">\n\t\t\t<div class=\"elementor-spacer-inner\"><\/div>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-c61bdfb elementor-widget elementor-widget-text-editor\" data-id=\"c61bdfb\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<h3><b>HOW CAN METOS HELP YOU?<\/b><\/h3>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-554f7ac elementor-widget elementor-widget-text-editor\" data-id=\"554f7ac\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p><strong>Powdery mildew is a persistent threat to many crops, but with METOS solutions, you can track, and prevent outbreaks before they happen.<\/strong> Since powdery mildew fungi are largely affected by environmental conditions, it is important to precisely monitor the condition and disease risk.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-ebb467e elementor-widget-divider--view-line elementor-widget elementor-widget-divider\" data-id=\"ebb467e\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"divider.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-divider\">\n\t\t\t<span class=\"elementor-divider-separator\">\n\t\t\t\t\t\t<\/span>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-5a0aad8 elementor-widget elementor-widget-spacer\" data-id=\"5a0aad8\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"spacer.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-spacer\">\n\t\t\t<div class=\"elementor-spacer-inner\"><\/div>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-c8c3376 elementor-widget elementor-widget-text-editor\" data-id=\"c8c3376\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<h3><b>UNLOCK THE POWER OF TECHNOLOGY FOR FARMING<\/b><\/h3>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-b8ac671 elementor-widget elementor-widget-text-editor\" data-id=\"b8ac671\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>METOS has tools to alert the occurrence of various diseases, including powdery mildew, in different crops using different kinds of sensors.
