phytoiatric

Nelle agriculture in the industrialized countries and those emergrnti combating biological adversity was the winning strategy to protect crops.
The chemistry in this field has made great progress. The use of these products in large quantities has created several prloblemi as sterilization environments;
destroyed the shelters of predators / pests
were intro new exotic plants and their pests crand new diseases in environments where there are predattori natural. In the experimental field have discovered new methods of struggle, in fact, studying the life cycle of parasites has discovered a chemical communication (pheromones), and has been used to combat pests. Yes sono scoperti e allevati predatori fitofagi (lotta biologica).
L'utilizzo della fitoiatria può avvenire in due momenti:
PROFILASSI: consiste nell'agire preventivamente, cioè quando la malattia non ha ancora agito, in modo da impedire il processo infettivo.
TERAPIA: consiste nell'agire quando la malattia è già in atto.
i mezzi che vengono utilizzati in fitoiatria rispettano alcuni concetti:
mirano nei confronti del patogeno;
intervengono sull'ambiente redendolo più idoneo alla coltivazione e meno ai patogeni.
i mezzi usati in fitoiatria sono: mazzi agronomici, mezzi fisici e meccanici, mezzi biologivi, mezzi chimici, mezzi legislativi.
care of normal agronomic practices are being carried out in the detterminati moments, following the growth of plants and the cycle of the parasites. Some treatments may include: the choice of selected seeds, fertilizers with manure mature, hydraulic systems and pruning the fruit trees. Using seed
selezionatesi limits the possibility of sem inated infested plants. The
sistemazioniidrauliche and processing can eliminate the water much too avoid root rot.
pruning damage forms suitable for sunburn and Ariege,
Maccanico a physical act and creating obstacles to the life of the pathogen. Some strategies are: the sterilization of loam, cover the wounds adequate co mastics, and burn the branches screw. The fire may be better to eliminate the defoliators. Another practice is the sunburn, that are being made of transparent plastic sheets on the ground, the sun's heat eliminate all the parasites on the ground. The means are those
legislative action to prevent new pests. one of these means was to regulate the trade of plants, monitoring crops.
