1病虫害防治1.1休眠解除至催芽期落叶后,清理田间落叶和修剪下的枝条,集中焚烧或深埋,并喷施1次80%必备可湿性粉剂200~300倍液或1:0.7:100倍波尔多液等;发芽前剥除老树皮,同时喷施3~5波美度石硫合剂。1.2新梢生长期(1)2~3叶期这是防治红蜘蛛、葡萄毛毡病、绿盲蝽、葡萄白粉病、葡萄黑痘病的非常重要的时期。发芽前后干旱,红蜘蛛、葡萄毛毡病、绿盲蝽、葡萄白粉病是防治重点;空气湿度大,葡萄黑痘病、葡萄炭疽病、葡萄霜霉病是防
1 pest and disease control 1.1 dormancy lifted to the germination period deciduous leaves, clean the leaves under the field and pruning branches, concentrated burning or deep burial, and spray a 80% of the required wettable powder 200 to 300 times the liquid or 1: 0.7: 100 Double Bordeaux mixture; before stripping to remove the old bark, while spraying 3 ~ 5 Baume degree stone sulfur mixture. 1.2 Shoot growth period (1) 2 to 3 leaf stage This is the prevention and treatment of spider mite, grapefruit disease, Apolygus, grape powdery mildew, grape anthracnose disease is very important period. Pre-emergence drought, spider mite, grapefruit disease, green bug, grape powdery mildew is the focus of prevention and control; air humidity, grape anthracnose, grape anthracnose, grape downy mildew is anti
