Successful cultivation of a fig is interfered by many wreckers and diseases. From wreckers the most essential harm is caused by an inzhirovy ognevka, an inzhirvy listobloshka and an inzhirovy plant louse. From diseases – antraknoz, fuzarioz fruits and gray decay.
The Inzhirovy ognevka develops in three generations. Caterpillars skeletiruyut leaves, and in maturing of fruits eat their pulp, causing deformation and rotting.
The Inzhirovy listobloshka within a year gives one generation. Larvae, nymphs and adult insects eat cellular juice of leaves, and at high number occupy young escapes and fruits. As a result of mass defeat escapes lag behind in growth, leaves dry up and fall down. The damaged fruits are wrinkled and also fall down. Listobloshka is a carrier of a virus disease – mosaics of leaves, and on its sweet vydeleniye the sazhisty fungus reducing commodity qualities of fruits settles.
The Inzhirovy plant louse settles down, generally from the bottom party of leaves colonies, mainly, along the main vein of a leaf, further passes to escapes. Leaves and fruits. Meets ochagovo.
Antraknoz strikes leaves and fruits. Dark brown spots (their middle pressed) appear on fruits in the middle of June. Fruits rot, become wrinkled and fall down. The mushroom winters in fallen leaves and fruits.
Fuzarioz of fruits is shown in maturing though infection occurs during pollination. Having got in an inflorescence, the mushroom causes rotting of internal fabrics a soplodiya.
Gray decay strikes both escapes, and fruits. On fruits brown spots are formed, gradually increase and grasp all fruit. On a surface of the struck fabrics there is a grayish fluffy raid. The fruit decreases in the sizes, is mummified and remains in such look on branches for the winter.
For prevention of mass development of all these wreckers and diseases it is necessary to carry out to a winter time (December-February) fytosanitory to a scrap of the struck branches, to bring together them and in to burn. Fallen-down foliage and the mummified fruits is also necessary for destroying.
Further the main system of protective measures on a fig is reduced to carrying out processings in fenofazy a razdvizheniye cheshuj and prior to the beginning of maturing against an ognevka, a listobloshka and a plant louse.
The first spraying against these wreckers it is necessary to carry out in fenofazu a razdvizheniye cheshuj (roughly, it is the end of March). During this period good results give emulsions of mineral oils – preparations No. 30, 30S and 30V (concentration of a preparation of 2,5-3,0 %), obespechivashchy practically elimination of the wintered wreckers and causative agents of diseases.
In fenofazu emergence of leaves is used (April) against wreckers by fororganichesky preparations: for example, Aktellik (0,2 %) or Zolon (0,2 %), and against diseases to preparations it is necessary to add medsoderzhashchiya fungicid (The champion, Kuproksat, Ridomil Gold, Ordan – in the concentration recommended by producer companies (are usually specified on preparation packing).
The subsequent processings carry out in fenofazy cultural development a full oblistveniye (May) and emergence summer soplody (June) the same preparations.
In years with damp summer at the beginning of maturing of early grades one more spraying against gray decay with use specific fungicidov, capable to prevent development of this dangerous disease is necessary to spend (July-August). Are recommended: Topsin of M (concentration of a preparation of 0,1 %), Horus (0,02 % or Teldor (0,8 %).
