In article recommendations about pest control and peach diseases are made: kurchavost of leaves, mealy dew, east plodozhorka, fruit striped moth and peach plant louse.
Peach – the main kosyotochkovy fruit poroda the South of Ukraine. For a poluyocheniye of its big and stabilyyony crops it is necessary not only accurate observance of all agrotechnical receptions of cultivation, but also a svoyevreyomenny and qualitative primeyoneniye of pesticides for zashhity plantings from a complex of wreckers and diseases.
In system of protective meyoropriyatiya on a peach the osnovyony attention should be given to fight with kurchavostyu leaves, mealy royosy, east plodozhoryoky, fruit striped moth and a peach plant louse.
To begin protection of a peach it is necessary in autumn and winter period about scraps and destructions zayosokhshy and damaged by vrediyotel and diseases of branches. It is desirable to clear also shtamby and skeletal branches of the died-off bark, to remove and burn the mummified fruits.
Every two years early in the spring (it is possible in February windows, at tvozduxa aren’t lower +4 °C), before blooming of kidneys, for the purpose of destruction of pereziyomovavshy stages of shchitovka, lozhnoshchitovka, plant louses, pincers, and also causative agents of mushroom diseases, it is necessary to carry out processing DNOKom (concentration of a preparation 0,5 %) with addition of mineralyyono-oil emulsions (preparat 30; 30 In, etc., a kontsentrayotsiya of a preparation 1-2 %).
The beginning of blooming of kidneys – the main term of fight against a kuryochavost of leaves. Here efyofektivno use as medsoderzhashchy preparations (The champion, to Bla of a Bordeaux, xlorokis copper), such fungicidov as Horus, Is fast (concentration of a preparation 0,02-0,03 %), and combinations of Strobi (0,02 %) with Delan (0,7-1,0 %). In 7-10 days, especially if passed a rain, processing is necessary for repeating.
Protective measures on fight against mealy dew and klyasterosporiozy begin with the flowering end peach (subsidence of 75 % of petals). Ispolzuyut such preparations as Topsin of M (0,3 %) or Topaz (0,04 %) or It is fast (0,02 %) in a combination with Delan (0,1 %). In dalyyoneyshy, at need (a high infectious background, crude and rainy weather), the obyorabotka is desirable for repeating in 12-14 days. In total for sezon it is possible to carry out 3-4 oprysyokivaniye these preparations. In the same term begin takzhe fight against east plodoyozhorka (a caterpillar 1-3 age – white, 4-5 age – red, with the brown head) and a frukyotovy striped moth (a guseyonitsa brown, with light cross-section strips on a grayonitsa of segments). The development and damage terms put by danyony types, are similar: the peryovy generation damages preyoimushchestvenno young, not odyorevesnevshy escapes; posleduyuyoshchy generations eat as pobegami, and fruits. The damaged escapes postepenyono dry up, at young trees the krone is incorrectly formed, and the damaged fruits rot and fall down. Against these types carry out: on sortax early term of maturing – two processings by Zolon (0,2 %) or Aktelliky (0,015-0,03 %) or Detsis (0,05 %), nayochiny with fenofazy after a tsveyoteniye; average term – three processings; late term of a soyozrevaniye – four processings. In separate years on persike mass development of a plant louse, especially bolyyoshy peach, giving to 10 generatsiya during the season (vysasyvaet juice from a bark shtambov and branches is observed; at strong zarazheyoniya the bark of trees becomes wet and sticky), and peach lomonosovoj, razvivayushhejsya in 4-5 generations (edges of top leaves hardly zavorachivayutsya down along a tsenyotralny vein of a leaf; at big number of this look it is observed pokrasneyony leaves and a prezhdevremenyony leaf fall). The plant louse can vredit throughout everything perioda peach vegetations. At emergence of its first individuals on a tree at any time, but not in maturing plodov, it is necessary to carry out an obyorabotka insecticides: Bi-58 (0,2 %) or Dursban (0,2 %). Thus, the optiyomalny system of protection of a peach in the conditions of Ukrayoina’s South should include, at least, 6 processings during the season. At the correct soyoblyudeniye of terms and norms of a priyomeneniye of pesticides it will help you to protect a crop.
