Prevention of diseases and pests lesions

basic principle of preventive work with plants is to understand that a strong plant - healthy plant, and the disease is often easier to prevent than to cure.Prevention starts with the selection of varieties plants resistant to diseases and pests, which significantly reduces the need for the use of any means of protection.Varieties with high immunity exist in virtually all types of vegetable and fruit crops, mention of this feature, be sure to refer to the description of one sort or another.

correct landing site selection plants can also serve as a preventive measure, as from this indirectly affects their health.The place must be sufficiently ventilated, so that in the absence of ventilation and movement of air masses occurs stagnant air, which significantly increases the risk of

spread of fungal diseases In addition, depending on the needs of different cultures must be respected their needs in solar irradiance since shady damp placeand a lack of ultraviolet radiation is also often the cause of

the active propagation of harmful organisms, the emergence and spread of diseases.

Creation of favorable conditions for the full growth and development of plants is one of the fundamental measures for disease prevention, because a strong vigorous plant is much less susceptible to diseases and pests and are often able to cope with the disease itself by its internal resources.First of all, by creating conditions for the growth of healthy plants is meant to ensure balanced it with the necessary nutrients. If the plant lacks at least one of the vital elements, it causes some irregularities in its development cycle, which significantly reduces the power plant and makes it vulnerable to diseases and pests.It is therefore necessary to make a regular compost and other organic components to improve soil structure, fertilizing plants and carry out a timely analysis of the soil to identify possible adverse .ja plant performance.Regular and balanced Fuel type also plays an important army in creating the conditions for the growth of plants. correct watering depends on the degree of plant nutrient consumption.insufficient watering result is a delay in the growth of plants, which is forced to expend energy, and inability to obtain their nutrients with excess watering nutrients are washed I from the soil and unavailable to plants .

great importance for the prevention of diseases and pests have rotation and crop rotation for the season.Compliance with crop rotation for several years contributes to a significant reduction in the degree of destruction of plant pests.Many pests affect culture, relating to the same species.For example, cabbage and redkovaya flies can be harmful to both plants, so you can not land on a place of one kind of series, such as radish after the cabbage, radish, or vice versa.If you do not take into account the need for consistent change of culture for generations and redkovoy cabbage fly, flea beetle and cabbage butterflies, it will be excellent conditions for further development and expansion of the colony.A number of pests and pathogens of various diseases, such as cabbage Gurney lives in the land in a particular area for many years.Therefore, culture can be planted in its place not earlier than in 3-5 years.

Create mixed plantings crops is quite effective and promising means of preventing disease and pest control.In the wild, in the same area grow different types of plants that help to attract these planting a large variety of insects.Thus it is established the biological equilibrium between beneficial and harmful organisms and the impact of the latter on plants greatly weakened.For mass cultivation of a monoculture over a large area is much more likely to cluster in the space of planting this crop pests that can sometimes cause serious damage to crops.In this situation, the use of chemical plant protection products is unavoidable.Mixed planting in comparison with monoculture have a much higher resistance to pests, as the diversity of cultures attracts numerous species of insects.This creates a natural balance of power, and of the pests destroyed beneficial insects that feed on them.In addition, the mixed cultures of spatially restricted habitat individual pests and pathogens, specializing in

particular family of plants.Therefore, planting different crops on his garden plot, it makes sense to choose them of good neighbors that his presence will provide a protective effect.Particularly well established in this role pryanoaromaticheskie various plants and some herbs that have natural natural immunity to a number of common diseases.

However, it should be borne in mind that the result of the protective action of the plants in mixed plantings will never be the complete disappearance of pests, can only be expected to reduce their number.

cabbage butterfly lays its eggs on plants in the crop cruciferous crops, especially in the cabbage.Emerging into the light incredibly voracious caterpillars and can cause serious damage to the extensive planting of cabbage, they devour the young leaves of the plant at the stage

formed of head.This is weakening the plant, cabbage knotted poorly, which significantly reduces the yield


special role as neighbors for planting plants play that could deter their smell harmful insects or shoot them confused.Such plants are called repellents, that is repellent.The majority of insects, including noxious find their host plant by smell.For example, cabbage moth, flea beetle and cabbage mites are exclusively due to publish its smell.It is the same with the other cultures.Therefore, if planted next to any culture pryanoaromaticheskie plants or herbs, they will drown out the smell of their flavor delicious plant pests, making it difficult to find them, or deter insect pests.It is their aromatic effects on plant pest repellents protect culture.

great importance for the prevention of plant diseases in the garden playing compliance plant hygiene. no secret that the person can be a carrier of viral and fungal diseases in the garden.This can occur through use of contaminated instruments, by not removed promptly from the site or made into compost diseased plants and their parts, a carrier of the disease can also become infected planting material.To avoid such situations, it is necessary to observe a number of simple, yet highly effective hygiene measures:

should buy certified planting material only in specialty stores and nurseries to ensure quality.Buy plants beside the road with it dangerous as one diseased plant can

value of mixed plantations to prevent the spread of pests and diseases

in mixed plantings of mass distribution of pests is constrained due to the diversity of plant species, since it is difficult for a number of harmful insects searchhost plant.8 monoculture this constraint is missing.There pests and pathogens is on the principle of the epidemic from one plant to another, covering the number of plants.

In mixed planting rows of different families create natural barriers to the spread of specific for each pest and diseases.

Many crops such as pryanoaromatiches-Kie plants, a number of vegetable crops have a daunting smell, which fear different groups of pests, so with a successful combination, they can deter them from their neighbors on a bed.

When mixed plantings may share the same culture to grow for several seasons in the same place, it is almost impossible when monoculture due to the accumulation of soil pests and pathogens.

example from the south, because they can become a source of destruction oleander cancer.

damaged places and wounds on the plants must be immediately disinfected and treated, as in wound infection or may penetrate there zavedutsya infection and the plant will become a hotbed of infection for the garden.

All the plants in the garden should be inspected regularly to timely detect possible defeat diseases and pests and to take the necessary measures to prevent the epidemic.

tool should be carefully disinfected to avoid the possibility of transferring the infection in the garden.It should be especially careful when trimming trees and shrubs.In the transition from one tree or shrub to another you need to change the tool or to carry out its complete disinfection.When you divide the rhizomes and tubers of ornamental plants should also be careful, because one infected tuber can cause destruction of all plants.

important precaution is not cut, and breaking out stepchildren tomatoes without the use of tools.This should be done in a timely manner, trying not to offend and not to injure other stepchildren or the plant itself.Justify such a measure is a precaution in case of truncation gladioli.Experienced gardeners are advised not to cut and break out the flower stalks, or to use for each individual plant a knife or blade.
