If the spots on the leaves of off-white color and around the perimeter are surrounded by a dark border - this is Septoriosis .It is caused by a fungus.

If you do not treat the plant, yield losses in septoria are significant. Can reach up to 50% of the total mass.

Fungus infects the leaf plates first, then the stem, then the fruits.

The causative agent of septoria is the fungus

. Aphid on the seedlings of pepper.

. Aphid is a transparent small insect( 0.3-0.8 mm).Parasitic on indoor flowers, vegetable and garden crops, sucking the juice from the leaves, petioles, stems.

There are many kinds of it( 3500), almost all polyphages. There are monophagous species that parasitize plants of the same species, but they are smaller. He lives in colonies.

The first sign that an aphid has appeared on the plant - ants scooping up the stalk. They are lovers of the sweet liquid that the bug allocates to the surface of the plant. If the leaves began to curl, you need to inspect the back side. Aphids and its larvae are clearly visible.

It is easier to cope with aphids at the initial stage of infection. Colonies of insects grow quickly and cause great damage to the plant. Delay flowering, inhibit growth.

Females are winged; they migrate from plant to plant, laying eggs. During the summer one individual makes up to 10 clutches. Last laying autumn. Eggs overwinter. In the spring begins a new breeding cycle.

Pepper seedlings can suffer from several types of aphids:
