Signs of the disease
Phylostictosis, or brown spot, is also called a dangerous fungal infection. The first visual signs appear on the crown of fruit trees in the second half of spring. On infected trees, the leaves are covered with brown spots with a yellowish rim. Later, they increase in size, at the same time changing their color to a darker one.
If the development of the infection is not stopped, then after a while, cone-shaped bulges of a rusty hue are formed on the reverse side of the leaf plates. They contain fungal spores, which are easily spread throughout the area by rain and gusts of wind.
Infected leaves begin to wilt and fall off prematurely. Deformed (thickened) shoots covered with red spots slow down development. A weakened plant stops bearing fruit, and sometimes dries up completely.
Methods for combating phylostictosis
Treatment of fruit trees affected by brown spot begins in late autumn (after leaf fall). Infected shoots, even with a small area of damage, are cut off. In this case, the tools: garden shears, delimber, hacksaw - are disinfected before starting work.
Plant residues (fruits, foliage, cut shoots) are taken outside the garden and burned. The branches remaining on the trees are treated with fungicidal preparations. Places of cuts are disinfected with antiseptics, and then they are covered with garden varnish or a muddler made of clay.
Chemical treatment
For prophylaxis, at the beginning of the season, pears are treated with fungicidal preparations against phylostictosis: Horus, Revus, Skor, etc. Spraying is carried out in early spring, even before the start of the sap flow process.
Secondarily, trees are processed during the flowering period. And at the end of the season, shortly before frost, pears are sprayed again.
Attention! Experts recommend alternating chemical preparations so that the pathogenic microflora does not have time to adapt to one of them.
Folk remedies
For prevention and at the initial stage of plant infection, you can use safe folk remedies.
Horsetail decoction
To prepare the composition, use fresh (200 g) or dried horsetail (75 g). The grass is poured with 1 liter of hot water and put on fire. After 30 minutes after boiling, the container with the broth is removed from the stove.
The finished composition is used for spraying pears, diluting it with water in a ratio of 1:10. Processing is carried out twice, with an interval of 7-10 days.
Wood ash infusion
Wood ash (1 kg) and laundry soap (50 g) are added to a bucket of hot water. The composition is left to infuse for 24 hours. After a day, the finished product is filtered and diluted with water in a ratio of 1: 5. Plants are sprayed twice, with an interval of 10 days between treatments.
Soda solution
Baking soda or soda ash (5 tbsp. l.) and shavings of laundry soap (4 tbsp. l.) is added to a bucket (10 l) of warm water. When the components are completely dissolved, the solution is ready for use. Trees are processed 2 times, maintaining an interval of 1 week.
Attention! Processing pears from brown spotting is carried out on cloudy, windless days or at hours when there is no exposure to bright sunlight.
Treatment of fruit trees against phyllostictosis requires additional efforts from summer residents. Careful care and preventive measures that prevent the development of fungal infections will help to save the garden.
