Asparagus is very tasty and healthy: it is rich in fiber, minerals and various vitamins. And this nutritious beauty grows like the most ordinary vegetable - in the beds in our gardens. Many summer residents appreciate it very much because the first harvests of young shoots can be harvested in April or May, because asparagus is one of the earliest crops. But sometimes the joy of anticipating a rich harvest is overshadowed by destructive ailments that affect this delicate plant. It's time to figure out what wonderful asparagus can hurt, and how to determine what kind of ailment struck her
Rust
It is the most harmful of all diseases affecting asparagus. In spring, yellowish specks form on young asparagus shoots, the centers of which are densely dotted with black pycnidia. And along the periphery of these spots, oval pads of etsidia can be seen.
Attacked by the unfortunate misfortune, asparagus noticeably lags behind in development and gives very few new shoots. And infected shoots are characterized by lower and extremely unimportant taste. Towards the end of summer, the affected asparagus turns yellow prematurely, and its vegetation ceases much earlier than its root system is formed. Accordingly, in this case, buds at the base of the stems do not have time to form, which contributes to a significant decrease in the yield of asparagus next spring.
Asparagus grown in areas with very close groundwater levels is considered particularly susceptible to rust attacks. If asparagus grows on soils that are not permeable to air and water, then it is also not immune from a destructive infection. In addition, heavy rainfall favors its development. To a large extent, it stimulates the development of rust and a lack of potassium, accompanied by an excess of nitrogen.
To reduce the susceptibility of asparagus to rust, it is recommended to spray it with Bordeaux liquid (1%) during the summer season. In the absence of such, it is not forbidden to use some other antifungal compounds. And all branches covered with fungal sporulation must be cut and burned (both in autumn and spring).
Cercospora
On the leaves of asparagus, the formation of dirty white or gray spots occurs, densely covered with a rather dark bloom of fungal sporulation. The harmful plaque consists of pointed and slightly elongated colorless spores, equipped with seven to eight transverse thin septa.
Root rot
As a rule, in most cases, the pathogen enters the asparagus roots with various mechanical damages. In addition to the roots, this ailment can also affect the root necks, which are painted in dark purple or dark brown tones. Both roots and root collars die off rather quickly as a result of damage by this scourge, and their death, in turn, provokes the instant death of aerial parts of plants. If root rot strikes asparagus plantings with special force, then rather solid bald spots will quickly form on the beds.
If the infection is not too strong, it is necessary to treat all areas of the accumulation of a destructive infection with "Fundazol". And after processing, they are isolated using a thick polyethylene film. As for heavily infected areas, it is best to get rid of them, and this should be done as quickly as possible.
Fusarium wilting
When this disease is affected, the shoots first turn yellow, and after a while the whole plant dies off. Unfortunately, it is almost impossible to get rid of this misfortune, since it cannot be treated, so you have to dig up the affected cultures and immediately burn them.
