Pest control methods
In order to fight pests gardeners widely use the following methods:
1. Insecticidal herbs
2. Sulfur √ as acaricide
3. Various chemicals (insecticides)
4. Bacterial chemicals
5. ┘and sometimes other biological methods.
1. Herbal products
The main advantage of herbal products over chemicals is that they aren▓t toxic for human or at least less toxic. However, the main disadvantage of such folk cures is that they are less effective as well. For example, they don▓t affect parlatoria at all.
Plants should be sprinkled all over with the infusions or decoctions prepared from certain herbs. Usually, you need to repeat the procedure 3-5 times every 7-10 days.
Insecticidal plants contain natural alkaloids, saponins, ethers and other posions. That▓s why you should be particularly careful when you work with some of them.
That was the favorite remedy of my grandma! The infusion should be used the same day it was prepared against aphis, thrips and red spider. Pour a glass of onion peel with a glass of warm water and let it stay for 24 hours.
It is not very effective against red spiders, but it is better than nothing.
Phytoncides contained in garlic affect aphis, red spiders, mealybugs, white fly, and are also very effective against some diseases. Pound a clove of garlic and pour it with warm water. Let it draw for 5 days in a dark place. Filter the resulting product and sprinkle plants with it. (By the way, it works not only with lemon-trees).
I recommend applying garlic when there▓re not only insects on your plants, but also some spots or dots on leafs indicating some diseases.
Decoctions made of yarrow kill aphis, thrips and red spiders. Yarrow must be collected when it flowers. The entire herb (except roots) is used. You should dry it before usage, because it is dried yarrow that provides better results.
Here is the recipe: pour 100g of dried herbs with 1 liter of water and boil it on the slow fire for 30 minutes. While it is still hot, filter it. I tried this remedy myself and it was more effective than two previous ones. Besides, it also doesn▓t smell bad. I recommend this decoction as the main remedy against pests among all herbal-ecological methods.
You can also ask for yarrow in drug stores if you need it urgently.
All parts of this herb are toxic. It is mainly used against red spiders and other pests.
Recipe: Pour 100g of pounded dry herbs with 1 liter of water and draw for 24 hours, then filter it. Add 2-3 g of soap into the infusion before sprinkling trees.
I think this infusion can be considered as a group 4 insecticide. Keep it away from children or, even better do not use it at all if they are children in the house.
This herb is highly toxic. It is used against red spiders and other pests.
The infusion is prepared the same way as for jimson weed.
Recipe: Pour 100g of pounded dry herbs with 1 liter of water and draw for 24 hours.
I suppose this recipe is also a group 4 insecticide.
Finely pounded (colloidal) sulfur kills all kinds of acarids. It is quite efficient remedy. However, it affects red spiders only if it▓s prepared and applied right. Sulfur powder isn▓t toxic by itself, but you don▓t want your house to smell like a demon▓s lair, right? Though this depends, of course.
Anyway, here is a step-by-step:
Take a tree out of the house, sprinkle it with water, and after the leaves become misted blow the powder onto them from a list of paper. If necessary, you can also add some sulfur into the soil in the pot. Then take the tree inside, where there▓s no wind.
I▓ve almost forgot √ the temperature must not be above 24ºC. Many gardeners often forget about that and create additional pain for themselves.
There are hundreds of chemical insecticides. I simply cannot list all of them. So I simply tell about the most common and the best ones. You can read how to use each chemical in the instruction included with it. It also says what insecticide group this particular chemical is in.
Remember √ 1, 2, 3 groups are prohibited to use in-house! You are more likely to poison yourself, while pests will merely laugh upon your attempts. The group 1 is the most dangerous.
ах-58 or пнцнп (emulsion) √ 10 drops for a glass of water. The treatment is performed in the evening. After 2 days the plant mast be washed over with water. This is a group 3 insecticide.
йюпантня √ an old and pretty well-known remedy. Affects all pests including small children. The treatment must be performed as described in the instruction. In real life works effectively only against aphis. This is a group 3 insecticide.
рхнтня (мхсхт-100) √ this is a toxic insecticide belonging to group 2 toxicity. Work well against parlatoria, acarides, mealybugs, thrips, aphis and others. This one is very good, but it is EXTREMELY TOXIC for human.
INSEKT SPRAI by Schultz (aerosol cans) √ it claims to be suitable for home usage.
INSEKT KILLER by Schultz (aerosol cans) √ it claims to be suitable for home usage.
Plint Pin arrows √ to fight red spiders. Simply put 3-4 pasteboard arrows into soil. They are sodden with a chemical of internal action. To be honest I expected more from this remedy, but at least you don▓t have to bother with toxic sprays.
юйреккхй √ this product has active fumes. The common usage is as follows: a plant is covered with big polyethylene sack, and is sprayed with some юйреккхй from below. It works very well against white flies, but as you probably could guess, it is hard to get the fly into the sack first.
юйрюпю √ a new and very effective toxic chemical insecticide of internal action. It belongs to group 3 toxicity. You need to sprinkle trees with it and also pour them. The chemical should be used to fight parlatoria, mealybug, thrips, aphis, white fly. For lemon-trees the concentration is 0,4-0,8 g/l. It is very effective against parlatoria, but doesn▓t even scary red spiders.
FASTAK (emulsion in ampoules) √ a system insecticide against wide range of pests. The active agent is alpha-cypermethrin. It kills all pests, and is a first group of toxicity insecticide. This remedy is EXTREMELY TOXIC! Poisoning your mother-in-law▓s parrot is as easy as pie. Use it only in open air with a respirator. Do not ever use it inside your house! Seriously. I recommend using this as a last resort when nothing else helps.
