The whole truth about herbicides from weeds on potatoes

When growing potatoes, you may encounter such an unpleasant phenomenon as growing on the same territory with the sowing of weeds and plants.

Weeds have no special requirements for growing conditions, so many of them can grow on a potato plantation, acting as a competitor to potatoes in the struggle for food and moisture.

If weed control is not produced, yield may drop to 55-60%That is unacceptable.

general information

Potato herbicides - special purpose chemicalsthat help in the destruction of weeds that grow close to crops.

It is worth noting that they are classified according to some features:

1. By the nature of the impact:


• selective actions that destroy only unwanted plants and herbs;
• continuous action that kill all vegetation.

If the land allocated for planting potatoes is very clogged with plant roots, then it is necessary to use herbicides for continuous action. It is recommended to make them in advance.namely spring or autumn.
In addition, continuous herbicides can be applied directly during planting, since their action lasts a maximum of 14 days, and seedlings of potatoes appear for 15-30 days.

The separation of drugs on the selective and continuous - a convention, since chemical selectivity may be changed with increasing dosage, timing and methods of application.
2. According to external signs of action:
• contact that affect the plant only in the places of their contact;
• systemic, which move along the system of plant vessels and are highly effective for controlling weeds that have a massive root system;
• preparations that, when introduced into the soil, destroy the seeds and roots of weeds.
3. In terms of introduction:
• used before sowing potatoes (spring, autumn);
• used during or immediately after sowing;
• weeds and potatoes used during the growing season.

Against weeds

Shoots

If the land allocated for planting potatoes is very clogged with plant roots, then it is necessary to use herbicides for continuous action. It is recommended to make them in advance, namely in spring or autumn.

Besides, continuous herbicides can be applied directly during planting, since their action lasts a maximum of 14 days, and potato seedlings appear at 15-30 days.

After shoot

After germination, the use of herbicides on potato fields is allowed only selective (selective). Properly chosen dosage does not harm the sowing, but will destroy unwanted plants.

After harvest leaves on the land areawhich is also destroyed by herbicides.

Against Convolvulus

Thanks to powerful roots field bindweed has resistance to many herbicides. Often, after a herbicidal treatment, the part of the plant that is above the ground dies off, but after that it re-grows.

By the time of harvest, there is an even greater clogging of crops with this weed. The fact is that herbicides "awaken" dormant buds, which later give a huge number of shoots.

In the year when the herbicides were sowed, the field bindweed does not form seeds - an active accumulation of substances occurs in the root system of the weed. For absolute weed control it is necessary to cultivate the land herbicides for several years in a row.

Application Methods

• solid (the entire area or sample plot);
• tape (stripes 20-30 cm);
• row.

Herbicides are represented by the following forms:

1. Solutions.
2. Powders
3. Emulsions.
4. Suspensions.
5. Aerosols.
6. Granules.

The form of the herbicidal preparation determines the method of its introduction:

• spraying;
• the introduction of granules or a mixture of the drug with fertilizers;
• dusting;
• introduction with water for watering.

The timing of drug administration depend on the vital phase of the potato, type and life phase of a weed plant, a form of herbicide.

For potatoes, herbicides are introduced under temperature conditions + 15 ... +24 degrees. At lower temperatures, the effectiveness of the tool is significantly reduced..

When using herbicidal agents for potatoes, the following conditions are necessary:

1. The seed should be at the maximum allowable depth for planting, so that the soil preparations do not affect the potato sprouts.
2. The soil should be loose, lumpy and moist, so that the distribution of herbicides occurs evenly.

Apply herbicides on potato plantations should not be the following cases:

• small planting of tubers;
• seed crops exposed to frosts;
• tuber crops suffered from pests and diseases;
• Potato varieties are highly sensitive to herbicides.

Spraying

Spraying plants with herbicides is divided into:

1. Close up.
2. The usual.
3. Small droplet.
4. Aerosol.

Spraying potato plantations gives a more effective result when carried out in calm weather. Do not use drugs during a drought or in strong winds.

Consumption rate

For herbicidal preparations of different manufacturers, their own consumption rate corresponds. Here are the most popular herbicides for potato use and their costs:

• Roundup - 1.4-4 l / 1 ha;
• Gladiator - 1.6-4.8 l / 1 ha;
• Tornado - 2-4 l / 1 ha;
• Arcade - 4-5 l / 1 ha;
• Lapis lazuli - 0.75-1l / 1 ha;
• Racer - 2-3 l / 1 ha;
• Molbuzin - 0.75 l / 1 ha.

More detailed instructions for use and consumable rates of other drugs are indicated by the manufacturer.

Basically These products are classified as low and medium toxic chemicals., but still when working with them should observe safety precautions.
