When growing potatoes, one of the main problems that any gardener faces is protecting potato bushes from attacks by various pests and, above all, the Colorado potato beetle. This overseas guest, who has been living in our area not so long ago, only since the 50s of the last century, has already managed to annoy everyone with his voracity and insatiability.
If you do not fight him, he is able to destroy all plantings of potatoes in one season, and then switch to other garden plants of the nightshade family: tomatoes, eggplants, sweet peppers, physalis and others. Therefore, what kind of methods have not been invented by gardeners to deal with this glutton and protect their potato plantings.
A lot of so-called folk remedies are completely ineffective, and no matter how sorry, but you have to turn to chemical preparations for help. Currently, several dozens of various drugs have been registered to combat the Colorado potato beetle, but even among them it is difficult to find a drug that would act with 100% efficiency. One of these drugs is Commander.
At least the reviews about him are mostly very positive.
Description and characteristics of the drug
Komandor is a contact-intestinal insecticide that has a systemic effect. That is, when applied to different parts of the plant, it is able to quickly penetrate into plant cells and spread throughout all plant organs. Usually their action is not as fast as that of contact preparations, but longer and more reliable.
The commander is considered quite effective against a variety of sucking and gnawing insect pests: the Colorado potato beetle, whitefly, bear, aphids, thrips, wireworms, psyllids and many others. Its action is based on the fact that, having penetrated the body of the pest, it completely blocks its nervous system. Because of this, insects cannot eat, move, and soon die. Commander equally well acts both on adult insects and on larvae.
The main active ingredient of the Commander is imidacloprid, vrk 200g/l.
For the destruction of insect pests, the following forms of treatment using the Commander can be used:
- spraying;
- Watering the soil;
- Treatment of seeds and tubers.
Commander is a water-soluble concentrate. It is usually packaged in small containers: 1 ml ampoules and 10 ml vials.
The drug Commander has the following advantages:
- It is a systemic drug that provides long-term protection of planted potato bushes for 20-30 days.
- Economical in use: only 10 ml of the drug is needed to process 10 acres.
- Effectively acts against many types of insect pests.
- Does not cause resistance.
- It retains high protective properties even in hot weather, which is important for residents of the southern regions.
- Maintains stability even in rainy weather.
Commander refers to substances that pose a moderate danger to humans (hazard class 3).
When working with the drug, it is necessary to observe the usual safety measures for such substances: protect the skin of the body with protective clothing, shoes, gloves, goggles and a respirator. Never use food utensils to prepare the working solution. At the end of the treatments, you need to wash your hands and face with soap, be sure to rinse your mouth and wash clothes.
Using the Commander for processing potato tubers
After a detailed acquaintance with the instructions for using the Commander, perhaps many will no longer want to mess with spraying potato bushes. Moreover, for this it is still necessary to wait for the onset of ideal calm weather. This is where the wonderful property of this drug comes to the aid of gardeners.
It is only necessary to take into account that the protective effect of the drug is not very long, about 20-30 days. According to the manufacturer, the protective effect of the Commander is maintained from the first shoots to the appearance of 5-6 leaves on a potato bush.
So, the processing of planting tubers by the Commander is carried out immediately before they are planted in the ground. To obtain 10 liters of the finished working solution, proceed as follows: dilute 2 ml of the Commander preparation in one liter of water. Then, with constant stirring, bring the volume of the solution to 10 liters. After that, germinated potato tubers prepared for planting are laid out on a flat surface, preferably covering it with a film. And they are carefully sprayed on one side with the Commander’s working solution. Gently turning the tubers over to the other side, spray again. After that, after drying the potato tubers a little, they can be planted in the ground.
Interestingly, the Commander can be mixed with many growth regulators and fungicides, such as Epin, Zircon, Maxim. Warning! Only mixing with drugs that have an alkaline reaction is contraindicated.
Therefore, before setting up experiments, it is necessary to carefully study the instructions.
Commander Plus
To make life even easier for gardeners and summer residents, a modified Komandor plus preparation was released a few years ago. Its main purpose is precisely the processing of potatoes before planting. The composition contains two bottles: one with the Commander, the other with Energen AQUA. Energen Aqua consists of potassium salts of humic acids and is used to increase the yield of potatoes, protect them from stressful conditions. It also helps to reduce the amount of nitrates in grown potatoes. To prepare a working solution, first the required amount of Energen AQUA, then Commander, is dissolved in a small amount of water, and the solution is brought to the required volume with constant stirring. The resulting solution is used to process potatoes in the same way as a regular Commander.
Feedback on using the Commander
The commander is quite popular among both gardeners and summer residents, so reviews about him are mostly positive. But they use it more often for spraying and protecting already adult potato bushes from the Colorado potato beetle. However, there are those who processed potato tubers with the Commander before planting.
Conclusion
It is obvious that the Komandor drug does a good job of protecting potatoes. Expect miracles from him, of course, is also not worth it. But when choosing a suitable potato protection against various pests, and primarily from the Colorado potato beetle, you should pay attention to this drug.
