Biological plant protection of vegetables: aphid, potato beetle, thrips

There are plenty of plant species in a vegetable garden. Everybody develops his garden according to his own needs. But it is not easy to find the right biological solution for different plant protection problems, so I'll summarize them for the major pests now!

There are some who grow only some of the main vegetables in their garden, but there are those who try to plant all of them. And for those who want to produce vegetables for themselves, its main interest is not to use coarse chemicals to make chemical-free, really healthy, vitamin-rich vegetables come to the family's table. The aphids are found on almost every plant.

APHIDS

As a result of their sucking, the leaves are distorted and retained in their development . Selected by the lice honeydew ants they are also very fond , and Secondary symptoms appear as a black sooty mold coating in the plant. Additionally , aphids can carry and distribute various viruses , causing severe loss of yield and deterioration.

HOW DO APHIDS SPREAD?

During the summer, aphids develop one or more winged shapes that look after a new plant and establish a new colony when settled there. These colonies can be captured with a yellow color trap , which can reduce the later on aphid stock in our crop plants. It is recommended to place sticky sheets at the beginning of summer 10-15 cm above the plants, one to two m² each. After filling the surface, it must be replaced.

The following biological preparations can be used to control already planted aphids:

- Vectfide The paraffin oil-based product is recommended for use in 0.5-1% solution when the first aphids appear.

- Azadirachtin-based bio-insecticide , an extract from an Indian shrub that can be used against various sucking chews. In addition, two members of the Aphidius quarrying genus are commercially available and can be used in closed cultivation equipment with great success. These should be introduced in the immediate vicinity of aphid colonies at a rate of 0.5-1 / m² for at least 3 weeks. The quail put their eggs in aphids and the hatching beast picks up the aphids from the inside, then, after it develops, leaves the mummy and parasites the new aphids. In many cases, if aphid pressure is low on plants, it is enough to promote the use of environmentally friendly pesticides.The proliferation of aphids' natural enemies - ladybirds, veils, and rattlesnings - and their "work" disappear from aphids.

POTATO BEETLE (LEPTINOTARSA ​​DECEMLINEATA)

Mostly it damages potatoes, but it feels good on tomatoes and eggplant . The eggs are placed on the back of the leaf, and as the larvae hatch, they are already damaging the plant by chewing. Novodor is an excellent use against these young larvae, of which 80-100 ml is needed for 10 liters of water and is recommended for 10 days. Especially the peppers, tomatoes, cabbages, legumes and sweet corn are endangered by the cotton owl, cabbage owl and cornflower caterpillars. Against Trichogramma petefürkész wasps (TRICHOPLUS) and Dipel gage can be controlled. These two formulations can be used alternately.

The peters are sold in small capsules , of which 2 to 4 pieces are to be placed 100 m² at the start of drawing butterflies. These poppy grains will put their own eggs into the eggs laid by the butterflies, so the useful ovary will hatch and not the damn butterfly.

The Trichogramma treatment should be repeated daily 10-14. But we can also defend against the above-mentioned pests with Dipel . This product is the most effective against young larvae. 30 grams of 20 liters spray. It is also worth repeating the spray every 10 days.

WESTERN FLOWER TRICKS

It is a big problem when it comes to growing foil and green peppers . We can track their settlements with blue traps and, for their defense , we recommend Spin Tor for 10 liters of spray with a dose of 2 ml every 2-3 days after the introduction.

Greenhouse mildews, or glasshouse flies, can also pose a greater risk in foil tents and greenhouses . For their prediction, yellow color traps can be used, and the azadirachtin-based bio-insecticide, which is still authorized, is highly effective.

In addition to pests, pathogens can also threaten our crops, such as phytoplankton , which is particularly dangerous for potatoes and tomatoes. We can only defend against it with preventive treatment. The appearance of this fungal disease is mainly due to humid, wet conditions, in which case it is worth treating with copper-containing Kocide 2000, of which 20 g is required for 10 liters.
