Anyone with a garden or a vegetable garden, knows what a weed.With each arrival of spring but pleasant bustle, we are waiting for the uncompromising battle.And not always a man emerges victorious in it.Weeds are less demanding in terms of growth, they have more chance of surviving than those of crop plants.For example, potatoes can not survive without human care, without water, fertilizing.And weeds growing next to it, on its territory and are its rivals in the struggle for nutrients and moisture.If they do not destroy, besides reducing the commercial quality of tubers, the emergence of various diseases, the inconveniences in the collection of potato crop losses could reach up to 50%.And it's pretty sensitive.Because the poor every weekend vacationers spend a few hours of their time to weed the garden, rather than spend those hours for a more interesting occupation.
Properties preparation "Lapis"
Some categorically recognize the chemistry, fearing to poison the soil and themselves struggling with weeds by mechanical means.Others start to look assistants.There are several effective prescriptions for killing weeds in potato.One of them - the use of herbicides, special preparations for controlling harmful plants.For processing potatoes there is a group of tools from different vendors.To date, the drug "Lapis" of weeds - the main herbicide.He destroys the perfect annual weeds to planting potatoes.Penetrating into the leaves and kills them.Also valid for 1-2 months through the soil to the growing weeds.
drug suppresses annual dicotyledonous and cereal pests (cornflower, quinoa, ragweed, pigweed, thistle, dandelion, chamomile, sow thistle, etc.).He when used properly, has no negative impact on the potatoes.Produced means "Lapis" of weeds in powder form, which includes metribuzin 700g / kg.Packaged in sachets of 20 g
methods and processing time
contribute to "Lapis" of weeds in two ways.The first - a single.Spraying is performed prior to the soil of the crop at the rate of 0.7-1.4 kg / ha.An important point: the tubers must be recessed into the ground optimally to the drug could not affect the zone of germs.For effective results, and the uniform distribution means the soil should be moist, loose and lumpy, the ridges are well settled.Windless weather is desirable.
Method 2 - twice.First time sprayed with the soil before sprouting potatoes normally 0.5-1 kg / ha.The second processing is performed once in a dose of 0.3 kg / ha Potato sprouting height of 5 cm and at the time when 70-80% of them.
application rates
applying the preparation "Lapis" of weeds, you should observe the exact dosage according to the manufacturer's instructions and caution.Immediately before use prepare a solution: a large bucket in 1 liter of water dissolve 1 package of preparation, stir and top up another 5 liters for primary treatment (pre-emergence of culture).If the solution to prepare a secondary procedure, the bag 1 is diluted in 20 liters of water.Ready solution is immediately used, not stored!
dosage also depends on the composition of the earth and humus content in it.The maximum dose "Lapis" is used in heavy soils, and light - minimal.If the land contains less than 1% of humus, then due to its weak absorption capacity of the herbicide is not used at all.In peatlands, soils, humus containing more than 6%, wetlands spraying should be carried out when the weeds have grown.Early potatoes are used lower rates of drug (less than 0.5 kg / ha), at a late - higher.The treatment is best carried out at a temperature of 15-20 degrees C. If the cooler or rain has passed after the treatment, the effect is markedly reduced.After 2 weeks, the weeds are killed.
Contraindications for use herbicide
Do not use the "Lapis" of weeds when potato seedlings were affected by frost, pests, shoots sick or very weak.Also, when the sensitivity of varieties to herbicides and their negative impact on the growth and development of the plant should be abandoned chemical treatment.
to be careful and follow safety measures, using a means of "Lapis".Weed control using herbicides eliminates the labor-intensive weeding, and even increases the yield.But we should remember that this method is not secure and is justified only when other measures to destroy weeds failed.
