Onions are culture which gardeners put one of the first on the site in the spring. Even the beginning gardeners do not neglect cultivation of this vegetable, and it is unsurprising, these plants do not demand special care, perfectly grow even on infertile soils. The only thing that culture — processings demands from wreckers before landing, without it lukovichka can be attacked by onions fly, and it, naturally, will affect productivity.
Naturally, it is better to observe prevention measures against such insect as onions fly. For this purpose it is enough to dig over before landing bed with addition in it of ashes and sawdust of coniferous trees. The fact is that resinous sawdust it is not pleasant to data wreckers, and parasites try to avoid similar soils. Moreover, the above mixes excellently fertilize soil. You should not forget that fine prevention is also observance of crop rotation: it is necessary to plant onions on the same bed not more often than once in five years.
As for soaking of onions in solutions from wreckers, either solution of potassium permanganate, or hot water is ideal for this purpose. In the first case the seeds ret in solution of average concentration for about 15 minutes then wash them with warm water and overhear a little. The planting stock is ready to landing. In the second case to destroy larvae of insects, onions are processed as follows: water is heated to temperature of 45 degrees, put in it pilferers and left for 15 minutes. If for processing more hot water (about 50 degrees Celsius) is taken, it is enough to leave onions in water for two-three minutes. You should not leave for longer time, otherwise there is risk to damage planting stock. Perhaps, it will also not affect viability, however it will affect immunity of plants not in the best way. At immersion in water the emerged seeds are removed as they are patients.
After soaking of onions in special solution it is desirable to sprinkle planting stock with in addition tobacco dust. Tobacco dust can be mixed ashes (1 to 1) and for sprinkling to use mix. After landing it is useful to spill out all bed this structure, using for the procedure about 100-200 grams of product on square meter.
If the onions fly attacks nearly an every year landings, then in this case together with the above-mentioned it is necessary to add facing of beds tomato tops of vegetable. The onions fly does not take out smell of tomato tops of vegetable, this way works on ""hurrah"" from this wrecker. The only minus so it that the tops of vegetable quickly fades this way is short-lived. However exit is: it is possible to plant tomatoes near onions, or in row-spacing of onions landings.
