Pests of beet and carrots

A beetroot flea is a small insect( 1.5-2.5 mm) black with a greenish metallic luster, an elytra with oblong acicular fissures. The larvae are white, with a brown head, up to 5.5 cm long. Adult beetles hibernate under the remains of plants and in the upper layer of the soil. The larvae live in the soil and feed on the roots of beets and weeds. Control measures. Treat plants with tobacco dust or, more effectively, with a drug spark.

The beetroot miner fly is similar to a housefly: 6-8 mm long, ashy with a dark longitudinal strip on the abdomen. Eggs( 0.6-0.8 mm) white, adult larvae( 5-9 mm) with pointed front and widened posterior ends. The larvae make passages in the leaf plate. Locations of the courses of browning and withering. The strongest defeats are in late May - early June.

Control measures. Destruction of weeds, autumn digging of soil. In the case of a mass appearance of a pest, plants should be sprayed with carbophos( 60 g per 10 liters of water) or with a spark preparation( 10 grams of 10 liters of water).

Beetroot aphids are small( 1.5-2 mm) insects. Females are wingless or winged, black or brown in color. The larvae are similar to adult females, but smaller, dark green in color. The aphids suck out the juice on the underside of the beet leaves. Damaged leaves curl down. Control measures. Spray the preparations with a spark of Bio, phytophythm or fast food according to the instructions.

Carrot fly is a small insect( 4-5 mm long), brilliantly black with a rusty-yellow head. The wings lie horizontally on the back and protrude beyond the end of the abdomen. Eggs white, elongated, elongated at one end. Larva vermiform, without legs, with a clearly expressed head, light yellow, shiny, 6-7 mm in length. Hibernating in the soil, fly in the second half of May, during the flowering of apple and mountain ash. Eggs are laid in late May - early June. The larvae gnaw on the rootlets of young plants, and later penetrate into the root crop and make traces in it. After 3-4 weeks, larvae pupate in the soil in a brown false cocoon, after another 30-40 days, flies of the second generation appear. Larvae of this generation are born in August-September and damage already large roots. Control measures. To save the crop helps sow carrots near the onions. Spraying between rows in the spring with wood ash and processing of carrot crops with a mixture of tobacco dust and ash( 100 g / m2) are also effective. From chemical preparations apply the actinic( 30 ml per 10 l of water).
