The means (instruments and products) to be used to fight against diseases and parasites closely depend on the importance of your rose garden. Know also that diseases and pests are often more important near cities than in the countryside.
If you have only a few roses, planted in the ground or in pots, it is often enough to buy a spray can containing a multipurpose insecticide; it almost always helps to get rid of most pests affecting your roses. This type of equipment, quite expensive considering the small amount of product sold, proves a very convenient job. It also exempts investment in spraying equipment.
Sprayers without pressure
If you still have few roses to treat, you find that some parasites are resistant to aerosol spray, you must resort to the use of a specialized insecticide adapted to the parasite that has resisted. You can then acquire a small manual sprayer, trigger operated pump. There are one-liter models and less, others up to two or three liters. In the first case, the spray head is associated with the tank. In the other, it is connected by a rubber tube, the tank carrying shoulder. This material has the advantage of also serving drench seedling in boxes and sprinkling foliage of some houseplants. It can also be used for the application of foliar fertilizer (absorbed by the leaves).
Pressure reserve sprayers
If you have a real rose garden, good size, you really need to acquire a real pressure reserve sprayer. This device makes it possible to treat quickly and regularly all of your roses. It is also very useful if you have a greenhouse for both treatments and drench seedling terraces, seedlings and foliage of house plants and orangery. There are two types of sprayers of this type. The first have a central pump acting on a kind of bottle; on these models, it is necessary to raise the pressure before use. Medium in weight, they are worn on the shoulder with a strap placed over the shoulder. The other type, derived from professional copper models, has a larger capacity; he is on his back, like a backpack. The pressure is obtained on this model thanks to a lever, which allows you to pump when you have the device on your back. It allows a continuous work and is suitable if you have many shrubs to treat (decorative and fruit, for example). Whatever the type of sprayer, be sure to use perfectly clean water; always avoid taking ponds, ponds or even cisterns. In fact, impurities and deposits can clog the lance or the spout. Most quality sprayers have a filter, which can be cleaned periodically. Some models, adjustable, dispense a more or less fine spray depending on the chosen irrigation grid. The only problem that can occur on a pressure sprayer is sometimes a failure of the seal. Take the precaution of buying a spare gasket at the same time as the appliance.
A number of treatments can not be applied effectively in spraying. It is necessary to resort to the powdering, which few amateurs do. Although many stores have lost the habit of selling this type of material, you will find it in most grain mills. It is a kind of mill with a reserve lid; a crank acts on blades that propel the powder into the dusting nozzle.
Powder should be avoided in windy, rainy weather and, in general, throughout the flowering period.
Some manufacturers (eg K.B.) offer real spray lances that can be processed using versatile solid cartridges. These take place inside the handle, and the sprinkling is obtained by the pressure of the water conveyed by a flexible garden hose. An extension lance allows the treatment of high branches and is very useful for the treatment of climbing roses and shrub roses. Sprinkling occurs with great regularity, which ensures the product processing the maximum efficiency.
They concern almost exclusively the destruction of ants. The latter do not directly cause damage to the roses, but protect the aphids, which produce a kind of milt which they feed on. It is therefore useful, when aphids and ants abound, to destroy them.
Poisoned baits, presented in small boxes pierced with holes, should be placed at the foot of the roses, on the passage of the ants.
The insects, or their larvae, are formidable enemies for roses. To fight against them, it is necessary to place near the shrubs of the insect traps, formed of a jar with funnel-shaped lid. This jar contains a sweet liquid that attracts insects, which get bogged down because they can not escape. The effectiveness of the system is counterbalanced by the blind and, ultimately, unecological side of destruction; the trap takes bees and other insects that cause no damage to roses, as well as those who attack them.
This method should only be used with reflection, in case of proliferation of a specific insect.
