How to protect gladioluses from diseases and wreckers?
From all variety of cultivated flowers enjoy wide popularity gladioluses.
It is a sort of klubnelukovichny perennials of family kasatikovy, including about 200 types.
Was considered that gladioluses are a little subject to diseases. However, as well as all bulbous, they can get sick too.
The most dangerous zabolevaniyay are fusariosis.
At fusariosis on bulbs appear it is red - brown oval spots. There are they in places of an attachment of scales and are as if pressed inside. It is visually possible to determine an illness at an initial stage by yellowing of tips of leaves. If to pass this moment, then yellowness extends from top to down on all leaves, roots die off and the plant perishes.
Too fungal disease.“ It is possible to catch“ it in rainy and not really warm weather. It is shown in a look darkly - brown spots and a bulb softening. A bulb it becomes black - brown and dries out. At other types of decay on leaves and stalks there are brown spots increasing in sizes and the leaves leading to drying up. Then the illness passes to a bulb.
It is characterized by emergence of small it is red - brown spots at the basis of leaves. Leaves and stalks at strong defeat by an illness become brown, and on bulbs brilliant yazvochka are formed. The disease develops on alkaline soils.
As prevention from various diseases gladioluses it is necessary to spray 2 - 3 times during the season “HOMOM“ or 1% potassium permanganate solution (1gr on 100 ml of water).
A good way of fight against diseases of gladioluses is processing of bulbs before landing.
Bulbs before landing are pickled 1 - 2 hour in warm darkly - pink solution of potassium permanganate or in solution of a copper vitriol (5 gr. on 1 liter of hot water, solution to cool), or we keep 2 hours in garlic solution (juice from 0,5 kg of garlic on 5 liters of water).
For fight against a bacterial scab if bulbs have no sprouts yet, it would be quite good to process them hot water (50 - 55*C) within 15 minutes.
After these procedures of a bulb night, on the eve of landing, are kept in infusion of wood ashes.
Coming back to fusariosis, I want to tell that in recent years receipt of sick bulbs, not only gladioluses, but also other bulbous, goes from Holland. This country is the main supplier of bulbous cultures and tries to convince buyers that these diseases are not dangerous. However, it not so! Similar diseases can destroy all landings easily. So what upon purchase of bulbs I advise more attentively to examine them.
And now to “favourite“ wreckers.
One of the most dangerous enemies of gladioluses - trips , the small insect is black - brown color with an orange paunch. Nesmotryana the scanty size, only 1,2 - 1,4 mm, it is quite prolific and gluttonous. Adult individuals and their larvae eat juice of plants why leaves turn yellow, and flowers and buds are deformed and perish. After “lunch“ on leaves they pass to a bulb. Broths of plants do not act on them.
For fight it is possible to try several ways.
Processing of bulbs the preparation “Karate“ (1 - 2 ml on 10 liters of water), “Fitoverm“ (4 ml on 0,5 liters of water), “Fufanon“ (according to the instruction). Any of these preparations processes bulbs of gladioluses. Previously to place them in a package, to inject there any of preparations and to stick. To leave tied for 2 - 3 days. Then bulbs to pull out and put in soil, or to send for storage. It is possible to carry out by these preparations processing from a trips and bulbs, and vegetiruyushchy plants.
Well, and fight against a plant louse to all of us is well-known.
Perfectly! With diseases and wreckers coped! Smart gladioluses!
