What is carrots?

carrot fly or psil rosae are garden pests that attack mainly carrots, pastines, celery and parsley. It is their larvae that cause damage under the soil, making it difficult to detect their presence before the crop is pulled out, although the leaves above the ground can be colored. Mržková fly can have up to three life cycles every season. The first laying occurs at the beginning of spring and larvae of a hatch within ten days. Initially, the roots of carrots feed on, but then they throw themselves into the real vegetables and create small burrows, which then allow mold to enter and make the whole carrot rotten. The larvae then develop into a small black carrot fly, which flies very close to the ground. The whole process is repeated in mid -summer and again at the end of autumn and the larvae remain in the ground, during the winter months they hibernate.

The main problem with carrot flour is that it is often not detected until the vegetables are pulled to eat. Many methods have been tested to prevent infestation. Mržková fly is attracted by the scent of carrot that can beto forge from a long distance. In order to prevent them to be attracted to the crop, the carrots should be well distributed during planting, minimizing the need for thinning. When harvesting the crop, the carrot of tags should be at dusk, preferably for the evening without the wind, because the carrots are active only during the day.

Since the fly can fly only about two feet (61 cm) from the ground, cover the plants with a protective penetration or a double -sided high barrier around them or plant them in flower pots that are kept high on the table can be effective. The timing of carrot planting to miss three active periods of larvae of carrot flies can also help. Different ways of connecting with other crops, such as to propose onions, but the efficiency has not been proven. It is believed that planting strongly smelling plants can make the fly difficult to detect the presence of carrots.

When the carrots attacked the larvae, the leaves can orange and then yellow. In many cases, however, the effect is observed only on carrots when you aregate. The carrot can be disfigured and the end often has small holes or burrows in it and can blacken blackens due to molds. Some carrot varieties are more resistant to carrot fly than others.
