Скачать или смотреть REASON OF ROSE DIE BACK IN MONSOON & SIMPLE WAY TO PREVENT IT

Control
Non-chemical control
Plant roses in well-prepared soil, making sure that the roots are well spread out
Do not plant roses into soil that has grown roses previously, without taking remedial action. Change the soil to a depth of at least 30cm (1ft) and a width of at least 60cm (2ft). The use of a mycorrhizal additive at planting can also be considered although these products are still undergoing experimental evaluation into their effectiveness
Avoid soils that are prone to either drought or waterlogging
Feed plants in spring with a proprietary rose fertiliser and mulch the soil to prevent water loss
Remove all dead and damaged wood as soon as it is seen. Also remove weak and crossing branches during routine pruning
Pruning cuts should be finished cleanly, and made immediately above and sloping away from an outward facing bud
Chemical control
There are no fungicides with specific recommendations for the control of rose dieback. However, some incidental control of dieback may be achieved when using fungicides to control foliar diseases such as black spot, rust and powdery mildew.
