Using Commander to process potato tubers
When growing vegetables on a personal plot, every second gardener uses insecticides in the fight against the Colorado potato beetle, wireworm and other insects that threaten the future harvest. Among the most effective drugs that have proven themselves in user reviews is the commander for processing potato tubers and other vegetables. It is used for plants already planted on the beds and immediately before planting root crops.
Using Commander to process potato tubers
The insecticidal agent commander for processing potato tubers before planting and for planted in the ground refers to systemic drugs with high efficiency in the fight against insects harmful to vegetable culture. The main active substance is the highly toxic component that is a part - imidacloprid, the concentration of which is 15 of the total volume of liquid used to prepare the solutions for processing, or 200 grams per liter. The chemical preparation can be produced in ampoules of 1 ml or in bottles of different volumes - from 4 ml to 100 ml.
The insecticidal agent from this series can be purchased in powder form under the name Commander Maxi.
Among the main advantages of using the drug to protect potatoes against the Colorado potato beetle, wireworm and other crop pests:
- maintaining the effectiveness of the action of the main active substance even at elevated temperatures,
- easy solubility in water with the formation of a stable suspension,
- lack of addiction (resistance) of pests to the composition,
- the possibility of using the drug for processing potatoes at any time of the year,
- wide range of action,
- low toxicity to vegetables and the environment,
- profitability due to the low rate of flow of the working fluid.
The advantage of the drug is that a single use of the commander for processing potato tubers in one garden season is enough. You can do this before landing and right on the bed, and there is no difference in the effectiveness of the result. The active component retains its effectiveness, accumulating in the cells of the plant and protecting it from pests.
An insecticidal drug to protect the potato crop is able to cope not only with the Colorado potato beetle, wireworm. Its advantage is a wide range - it helps against aphids, scares away the bear and butterflies, and also prevents damage to vegetables by rodents. The tool is able to effectively resist against adult insects - pests and their larvae.
An insecticidal agent for protecting potatoes from pests is used in the form of external processing of root crops.
The main ways to protect a vegetable crop from the Colorado potato beetle are to spray the working fluid on the bushes of planted potatoes or watering. An insecticidal substance with sufficient intensity quickly penetrates into the cells of the root system, stems and leaves of potatoes. A vegetable pest can receive a dose of an active toxic substance by eating potato tops or root crops and also by simple contact with parts of the plant.
The protective function of the drug while protecting potatoes remains active and effective for up to 35-50 days, which is enough for growing and harvesting.
A poisonous substance that enters the body of an insect, which is part of an insecticide, begins to act on nerve cells, exerting a paralytic effect on them, which paralyzes motor function and disrupts digestive activity. The final result of the action used to protect potatoes from pests is the death of an insect.
Take care in dry weather
Despite the numerous reviews of gardeners assuring the ability of the insecticide to protect potatoes to maintain their effective effect even in rainy weather and with heavy watering, to achieve a high result with a greater likelihood of fighting against the Colorado potato beetle, it is recommended that they process plants in dry and calm weather, when forecast no rain soon. This will allow better absorption of the active toxic substance into the cells of a potato plant. On the day of spraying a vegetable crop, experienced gardeners do not recommend watering the bushes.
Prepare a liquid for spraying or watering the potatoes based on a 10-liter bucket of water, 2 ml of active agent. It is convenient to do this by first dissolving the indicated amount of insecticide initially in a liter of liquid, thoroughly mixing it to the state of suspension, and then bringing the volume of the working composition to the desired amount.
It is recommended to process a vegetable crop from a watering can when watering or with a spray, if the method is selected in the form of spraying. You can do this in one of two possible ways:
- by spraying on foliage and stems or watering potato bushes already planted in the soil, the instructions for the preparation recommend spraying the plants using a freshly prepared composition to obtain the most effective result, moistening the foliage evenly,
- by using the commander to process potato tubers before planting them on the beds, for which they are laid out in a row, carefully processed and then dried, many prefer to cover the potato tubers processed before planting with a film, and after they have completely dried by the usual method, they are planted in soil.
Precautions and Other Factors
The insecticidal composition against pests shows its effectiveness, while ensuring safety in its use, subject to a number of conditions.
Speed and effect
The optimal temperature regime for the effectiveness of the drug is 12 '- 25'. These are the boundaries within which the active toxic substance that is part of the composition is able to work with the maximum positive result. The effect of protecting potatoes is already observed a few hours after. The manufacturer of the insecticidal agent guarantees a period of 100% protection of the vegetable crop against the pest for at least two weeks, with its preservation up to two months with a decrease in the percentage of effectiveness. The instruction to the commander does not provide for the alternation of the composition with other chemical insecticides and other drugs, without guaranteeing in such cases a positive result.
According to the instructions, the commander for processing potatoes does not apply a phytotoxic agent for vegetable crops, when the recommended dosage of the drug is observed when preparing the working fluid. It belongs to the third hazard class and to the second class for maintaining stability in soil. However, the duration of work with the drug for humans should not exceed three hours with the mandatory use of personal protective equipment.
It should be remembered that when processing against a pest by the commander of an already grown potato, it is possible to eat it after at least 20 days after the treatment.
In places where potato bushes are adjacent to apiaries, it is recommended to use the commander with due care, since its use often becomes fatal for bees collecting nectar from potato flowers.
Destruction and disposal
In the case of spillage of the concentrated composition of the commander, the active substance is sorbed by sand or a dry subgrade, clay or sawdust. After complete absorption of the composition, the contaminated material used as a sorbent is collected in a container and disposed of. The land plot, where the concentrated composition got, is treated with soda solution with a concentration of 10% or freshly slaked bleach with a concentration of 7%. After processing, the earth is dug up.
