class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p><strong>Oidium is a fungus of the Erisifaceae family,<\/strong> which is increasingly common in <strong>cannabis crops<\/strong>. It manifests as a kind of white powder on the leaves and <em>at first sight can be confused with mildew<\/em>. It usually appears in indoor crops and greenhouses rather than outdoors, as <em>it arises when a certain heat is accompanied by sudden changes in humidity.<\/em><\/p>\n<p>The spores of the Powdery mildew rest on the top of the leaves, and when the conditions are met they produce a kind of root that is responsible for sucking nutrients. Little by little it expands over the entire surface of the leaf and passes to others, and then<em> the leaves turn yellow and fall off.<\/em><\/p>\n<p>&nbsp;<\/p>\n<h3><span class=\"ez-toc-section\" id=\"How_can_I_prevent_or_eliminate_Powdery_mildew\"><\/span>How can I prevent or eliminate Powdery mildew?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>&nbsp;<\/p>\n<p>The best thing is to prevent it from appearing and to do so you need several things. The first thing to do is to keep the growing space as clean as possible. Also keep the humidity as constant as possible, and a temperature that does not rise above 27 \u00ba C. nor under 18 \u00ba C. And spray the plants with <strong><a href=\"https:\/\/pevgrow.com\/en\/4963-trabe-propolix-bio-stimulator-fungicide.html\">propolis<\/a><\/strong> weekly from the second week of growth.<\/p>\n<p>If you have to<strong> fight against Powdery mildew<\/strong> fortunately there are enough effective products on the market, such as <a href=\"https:\/\/pevgrow.com\/en\/5378-oidioprot-ecoprotec.html\"><strong>OidioProt<\/strong><\/a>, <a href=\"https:\/\/pevgrow.com\/en\/4784-oidio-killer.html\"><strong>Oidio Killer<\/strong><\/a> or <strong>Flower&#8217;s powdery mildew fungicide<\/strong>.<\/p>\n<p>&nbsp;<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Are_there_homemade_remedies_to_fight_powdery_mildew\"><\/span>Are there homemade remedies to fight powdery mildew?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>&nbsp;<\/p>\n<p>Yes, there are, and also quite effective if handled in time. Sodium bicarbonate has antiseptic, antibacterial and fungicidal properties among others.<\/p>\n<p>To eliminate oidium with bicarbonate it is necessary to mix water, oil and sodium bicarbonate in these proportions: 1 litre of water, 2 tablespoons of olive oil and 2 tablespoons of sodium bicarbonate. We mix everything well and with this solution we pulverize all the plants properly, with special emphasis on areas where we see oidium sprouts.<\/p>\n<p>&nbsp;<\/p>\n<figure id=\"attachment_30850\" aria-describedby=\"caption-attachment-30850\" style=\"width: 565px\" class=\"wp-caption aligncenter\"><img decoding=\"async\" class=\"wp-image-30850 size-full\" title=\"Effects of Powdery Mildew on cannabis\" src=\"https:\/\/pevgrow.com\/blog\/wp-content\/uploads\/2019\/11\/effects-of-Powdery-mildew-on-cannabis.jpg\" alt=\"Effects of Powdery Mildew on cannabis\" width=\"575\" height=\"760\" srcset=\"https:\/\/pevgrow.com\/blog\/wp-content\/uploads\/2019\/11\/effects-of-Powdery-mildew-on-cannabis.jpg 575w, https:\/\/pevgrow.com\/blog\/wp-content\/uploads\/2019\/11\/effects-of-Powdery-mildew-on-cannabis-227x300.jpg 227w\" sizes=\"(max-width: 575px) 100vw, 575px\" \/><figcaption id=\"caption-attachment-30850\" class=\"wp-caption-text\">Effects of Powdery Mildew on cannabis<\/figcaption><\/figure>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<h2><span class=\"ez-toc-section\" id=\"%F0%9F%92%BB_Botrytis_What_is_it_and_how_do_I_detect_it\"><\/span>\ud83d\udcbb Botrytis, What is it and how do I detect it?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p><strong>Botrytis is one of the worst fungi that can attack cannabis plants<\/strong>, once we see it has already caused damage. Also called <strong>grey mould<\/strong>, it is more common in outdoor crops than indoors, especially when the buds formed are wet.<\/p>\n<p>It is a<strong> parasitic fungus<\/strong>, as<em> is powdery mildew<\/em>, since it needs a host plant that it feeds on. But it also generates toxins that destroy coatings of our plants, leaving them unusable for consumption.<\/p>\n<p>Although Botrytis can appear in any stage of plants (even dead) it is more common to see it in the flowering and ripening phase. The first symptoms that can be seen are leaves with yellow tips or directly dry on the buds, as the first damage occurs inside them. If you look closer you can see a <em>kind of cotton in the flowers<\/em>, that bud would be to throw away.<\/p>\n<p>&nbsp;<\/p>\n<h3><span class=\"ez-toc-section\" id=\"How_can_I_fight_Botrytis_in_cannabis_crops\"><\/span>How can I fight Botrytis in cannabis crops?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>&nbsp;<\/p>\n<p>As always, the best thing to do in these cases is to <strong>prevent Botrytis from appearing<\/strong>. In indoor growing <em>control humidity and ventilation<\/em> to ensure that air circulates throughout the growing space. Outdoors try not to get the buds wet since they start to form.<\/p>\n<p>There are also effective natural fungicides that help prevent the appearance of Botrytis, in this case <strong><a href=\"https:\/\/pevgrow.com\/en\/5407-horsetail-agrobeta.html\">horsetail<\/a> or propolis<\/strong>. Another important thing is to <em>close wounds on branches and stems with healing products<\/em> to prevent external agents from entering.<\/p>\n<p><strong>Eliminating Botrytis<\/strong> is a very complicated task, it is best to cut the affected areas carefully so as not to spread the spores. There are products like <a href=\"https:\/\/pevgrow.com\/en\/5377-botryprot-ecoprotec.html\"><strong>Botryprot<\/strong><\/a> that are formulated for this mission, but it is a difficult problem to eradicate.<\/p>\n<p>&nbsp;<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Which_homemade_remedy_can_I_use_to_end_Botrytis\"><\/span>Which homemade remedy can I use to end Botrytis?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>&nbsp;<\/p>\n<p>There are no<strong> homemade tricks to completely eliminate botrytis<\/strong>. But there is a home remedy to prevent the attack of this fungus. <strong>Mixing skimmed milk, sodium bicarbonate and distilled water<\/strong> with a ratio of 4 parts water to each part milk, and 20 grams of baking soda to each liter of mixture.<\/p>\n<p>For example, if we want to make half a litre of product we have to mix 400 ml. of distilled water with 100 ml. of skimmed milk, stir well and then add 10 grams of bicarbonate.
