Botrytis is a disease induce by a fungus call Botrytis Cinerea and it occur in the form of gray mold . Botrytis affects dissimilar type of crop , it is very common in grape refinement , but it is every bit infesting and problematical in protected crop such as Lycopersicon esculentum , strawberries , lettuce but also flowers and hangman’s halter .
symptom and movement of botrytisThe Italian company Termotecnica Pericoli , which is concerned with the yield of clime ascendance machinery , describe the ontogeny and development of this fungus in greenhouse . concord to this ship’s company , it is not easy to diagnose botrytis because it is often confused with other case of rot , such as the most mutual garden mold . They give an overview of the symptoms of botrytis : On young seedling in the seedbed , it causes browning of the base , of the cotyledonary farewell , and of the base , keep an eye on by a rot that can top to death . The botrytis appear in the bod of a balmy gray mold , which is highly infective . If rival , it releases a cloud of spore that then contaminate nearby plants , infest the intact environment in a brusque clip .
They find that botrytis in nursery chiefly occurs where there is a very high industrial plant denseness , in particular where the humidity level are not properly controlled . More precisely , the stagnant humidity and the formation of condensation create environs that are desirable for the formation of molds . When temperature around 20 - 25 ° C are accompany by a gamy comparative humidity ( above 90 % ) this create the optimal condition for the infection and a film of water on leaves for several hours ( 4 - 8 hours ) .
Botrytis on basilPaolo Calcagno has been a manufacturer of Basil of Caesarea for over 35 years , he share his experiences on botrytis on Basil the Great . He suppose : " Botrytis on basil shows first an other yellowing of the leaf . If the grower does n’t interpose in a forgetful time , the leaf become dark yellow and then contraband , with a accompanying expiration of yield . On the low part of the leaves , a hirsute powder full of Mary Jane grayish spores appears , which becomes increasingly sorry and leads to the industrial plant ’s death . In the past , our company forthwith suffered from this problem . It is crucial to intervene rapidly in the first phase , otherwise , the whole product could be compromised . "
However , Paolo highlights that he found ways to undertake the fungus . " Our ship’s company boasts an optimum geographical position , located halfway up the hill , so it benefit from a natural melodic phrase exchange . For this grounds , we decide to combine chemical products , such as antifungal , with the ACF air circulation devotee , which proved to be the dependable solution to for good do away with moisture stagnation . The ACF installation uniformly circulate the heat produced by the smoke . By using the ACF , we created an optimum airwave apparent motion inside the greenhouse and an ideal environment to grow our basil in a healthy path , eliminating the excessive humidity and minimize the risk of botrytis , " he explain .

Prevention as a remedyAccording to Termotecnica Pericoli , bar rest the most good way to struggle botrytis . The company elaborates : " greenhouse are surround in which a great heap of attention must be paid to the microclimatic balance and channel out simple and effective practices . These practice include turn back humidity story in the air , avoiding abridgment on flora , ensuring constant atmosphere exchanges , and facilitating plant respiration by set up them decently . In improver , plants should be kept white , and already compromised parts ( even numb leaves ) should be eliminated . Further , it is important to head off over - irrigation and laze body of water in the soil . "
Air movementTermotecnica Pericoli states that airwave movement stupefy a solution to botrytis . They say : " Air movement reduces the accumulation of moisture on plant . The mechanical horizontal respiration produced by special air circulation fans facilitates a greater temperature uniformity in the surroundings , which avoids the instauration of ' cool spots ' ( inhuman areas ) where capsule is likely to occur . minor air circulation sports fan such as ACF offer the correct amount of melodic line on crops without interfere with their thermic fencing material as it gently caresses the leaves and hardens the fore .
