Pest and problem control in cucumbers and cabbage - specialist advice
Help cucumbers and cabbage
Our readers are asked to suggest effective ways to combat the brown spot of cucumber leaves. What do you advise?
NC: The brown spot of cucumber leaves is a fungal disease, common in greenhouses and film shelters.
On leaves first appear single, and then numerous brown spots of angular-round shape with a light center.
With a strong lesion, the leaves die, the plants die. The development of the disease is promoted by sharp fluctuations in air temperature and humidity. The infection is preserved on plant residues, in soil, on wooden constructions of greenhouses.
To prevent disease requires a set of measures: compliance with crop rotation. decontamination of the framework of greenhouses and soil, reduction of the relative humidity of air by ventilation or ventilation, treatment of plants with 1% solution of Bordeaux liquid. timely removal of diseased plants and all plant residues. I recommend several times a season to pollinate plants with wood or peat ash (50 g / m 2).

Many complain that cabbage heads are cracking. What should I do to avoid this problem?
NK: As a rule, cabbage cabbage of an ultra-early ripening group is cracked. In the Belarusian Institute of Vegetable Growing together with the Breeding Station. N. Timofeeva (Moscow) received an ultramarine hybrid Ilaria F1. forming dense heads, which, after maturing, do not crack for 2 weeks or more.
Medium and medium-late varieties of cabbage can also crack, especially if dry weather gives way to heavy rains.
I advise you to plant cabbage so-called conveyor belt: in several terms, to stretch the period of consumption of cabbages. Some vegetable growers-practices after tying the heads cut the roots of plants with a shovel, which reduces the likelihood of a problem.

The reader is also concerned about this question:
How to find the governess on the caterpillars of the cabbage whitewash? "Someone collects them by hand, others water the cabbage with a detergent solution.
It helps, but it's not enough. What do you advise?
N.K .: Here we need a set of measures: observance of crop rotation, timely destruction of weeds, which deprives many pests of additional food. Folk remedies have recently become ineffective due to the increasing cultivation of cruciferous crops, in particular. rapeseed, and addictive pests, even to chemical preparations.
To use a detergent I do not advise: it badly influences a condition of ground More effectively and safely in due time to use chemical protection means, as some of them are similar to natural vegetative toxins
So, "Denis" - an analogue of pyrethroids from Dalmatian chamomile, which is often used to combat pests in the garden-garden. It is important only to take into account the recommendations for use. In particular, the dose of application and waiting times before harvest.

Last year, all the cucumbers were speckled with coarse gray cracks. Why did this happen? How to prevent this in this season?

- Most likely, last year cucumber gnats, or rather, their larvae, which spoiled the harvest, started in your garden. Another possible cause is a cucumber mosaic virus that carries aphid. Both in the first and in the second case, in order to avoid problems in the current season, follow the rules of crop rotation, and before planting, spill the soil with Fitosporin (according to the instructions).
In addition, coarse gray cracks on cucumbers sometimes appear due to stagnant moisture at the roots. Dig the soil under the bushes - and if it is very wet, then stop watering completely for a couple of days.
Sometimes this problem occurs with a deficiency of calcium and potassium. In this case, dilute 1 tsp in 1 liters of water. potassium sulfate, still in 1 l - 1 tsp. Calcium nitrate, pour the solutions on the bed in turn at the rate of 1 liters per 1 m2 of soil.

Escape from midges and fleas
For protection against cruciferous fleas several times during the summer I squander cabbage and radish with sifted ash. And carrots and onions are similarly protected from carrot and onion flies.
To control the pests of the garden garden, I spray the planting with an ash infusion: 300 g of ash pour boiling water, boil 30 min., Let stand, drain off the sediment, add a little liquid soap.
