la prima vedere, par cosenile fainoase... cel putin asa arata in poza din cartea mea.
Combatere: desprindeti manual cosenilele pentru ca sunt protejate de insecticide de carapacea lor. frecati partile afectate cu un tampon de imbibat in alcool de 60 grade; dupa o jumatate de ora va fi usor sa le indepartati. (2 parti de alcool, una de apa adica)
tratament: inescticidelre pe baza de pitethrinoide de subteza (cipermethrina, deltamethrina, imidacloprida- care e sub forma de aerosoli) dau rezultate bune.

sfatul celor din carte: efectuati o taiere severa a plantelor atacate, eliminand partile acoperite de cosenile. tratati-le apoi pentru a evita o noua infestare.si stimulati crestrerea plantei prin aporturi regulate de ingrasamant diluat.

ia pana una alta un insecticid de spectru larg si da pe ea. si neaparat, izoleaz-o de celelalte plante. poate restul fetelor se pricep mai bine sa zica ce are plantuta ta...

e ciudat ca astea fainoase cica se dezvolta la temperaturi de 20-22 de grade. si acum sunt... dublu

Multumesc forte, sper sa o pot salva...Am spalat-o si am izolat-o..biata mea plantuta

Mama zice ca e Taphrina deformans, basicarea frunzelor. Uite aici info:

Peach leaf curl is a fungus disease called Taphrina deformans. It can cause defoliation and crop loss on nearly all varieties of peach and nectarine trees. The most common characteristic is the curling and crinkling of the leaves as they unfold in spring. Usually, the entire leaf is affected, but sometimes only small areas are involved. In addition to the curling, diseased leaves often turn red or purple. This disease also may occur on the fruit, blossoms, and young twigs. Diseased fruits will usually fall off of the tree prior to harvest. A diseased tree does not usually yield well do to blossom loss in the spring.
Luckily, peach leaf curl is one of the easiest fruit diseases to control. Leaf curl can normally be prevented with a single, well-timed fungicide application of an appropriate fungicide, either in the autumn after 90% of the leaves have fallen, or in the spring before bud swell. Remember, for effective disease control the fungicide must be applied at the proper time, and the tree must be thoroughly covered with the fungicide spray. When applying a fungicide, or any chemical for that matter, be sure to read the label and follow instructions to the letter. Be certain that you are using the correct product for the type of plant, as well as for the disease or pest you are using it to control. If leaf curl is severe, it is important to maintain tree vigor by thinning more fruit than usual, irrigation, and applying extra nitrogen fertilizer.
As far as the ants go, I doubt that they are causing to much of a problem to your tree, unless you also have a problem with aphids. Ants supposedly herd and protect aphids like cattle. Aphids tend to congregate on new plant growth. Salivary secretions cause a stunting of leaf and stem growth. If aphids appear to be a problem, there are many insecticides on the market, which will effectively control them, as well as the ants. A preferred and safer method would be to purchase a quantity of lady bugs next spring, and allow them to cure the aphid problem for you. The ants will just go about their own business, doing ant things.

Walpu (IMG:style_emoticons/default/kiss.gif) multumesc mult.

pesca pt solutie rupe o frunzulita doua si du-te la o sera, deci nu la magazine care vand si plante printre multe altele.
la sera sint specialisti (hopefully) si iti pot sugera exact ce sa cumperi. ba s-ar putea sa aiba si oameni sa vina sa ti-l stropeasca.

cleo, nici n-am stiut de asa ceva. mersi si tie. (IMG:style_emoticons/default/kiss.gif)
