Insectoacaricide with intestinal contact effect against leaf-gnawing and leaf-sucking pests. Active ingredient: Aversectin C, 2 g/L. Manufacturer: CJSC "Firm August." Analogue: Fitoverm. Chemical class: avermectins. It has a faint unpleasant odor. Available in 4 ml ampoules.
Mechanism of action: aversectin acts on the nervous system of the pest (insects and arthropods), causing its paralysis 8-10 hours after spraying, death occurs in 3-6 days. The protective effect on the leaves lasts 5-7 days (the drug is destroyed by natural factors).
Instructions for use
Castor fever penetrates the body of the pest upon contact with the solution - it is absorbed through the outer covers or after eating sprayed leaves in those places where the solution got. The drug is used to protect garden flowers, berries, fruit shrubs and vegetables, as well as indoor plants not only from the tick, but also from a number of other pests:
- flower thrips
- shields
- scales
- colorado beetle
- plant louses
- leaf wrappers
- weevil
- apple moth
- scoops
- cabbage and turnip white
- cabbage moth
Important: pincers are little effective against worms and scutes, completely useless against soil pests!
Storage of the working solution is not allowed! The solution must be used within one hour of dilution.

Comments rukodelie.net/plants: specified treatment times (intervals between spraying) are indicated for pest containment. It is assumed that on garden flowers, fruit and berry trees and shrubs, vegetables, spraying from pests will never reach 100% destruction, treatments are needed to prevent plants from weakening before flowering or fruiting and accumulate enough strength by winter. At home, the flower grower has one goal - to completely get rid of the tick, thrips or other pests once and for all. Therefore, we recommend repeated spraying from a tick twice with an interval of a maximum of 3 days, then change the drug.
In addition, it is necessary to take into account the individual development cycles of the pest: the timing of growing up - from an egg to a larva can take 3 days, maybe 7 or 10, it depends on the type of pest and on the temperature. So, in thrips, eggs mature in 6-7 days, feed on leaves for about a week, then go into the soil to a depth to complete development to adult flying individuals. Therefore, from thrips, the spraying interval is 6 days.
The instructions do not indicate the use of castor oil against strawberry mites, but it is quite possible to use it, especially when strawberries or strawberries are already poured with berries and other chemistry cannot be used. Strawberry mite on strawberries : 6-10 ml per 1 liter of water, frequency of treatments - three times in three days, spray only at a temperature of at least 24 ° C
Resistance
Manufacturers claim that pests do not get used to aversectin C drugs, so it can be used for several years in a row. This is outdated information, there is resistance, but it depends on the frequency of use of the drug and the type of pest. For example, scientists have found that populations of the red spider mite are extremely resistant to the drugs Kleschevit, Fitoverm and Vermitek.
Pinch reviews
In general, castor oil acts in the same way as phytoverm, many growers will call it a weak tool, it helps someone a lot. Why such conflicting reviews? The fact is that the drug helps only if the pest feeds on sprayed leaves or when there is contact with the integument of insects or arthropods (ticks).
If the plants have pests in the egg or non-feeding larvae stage, there will be no effect. In addition, adult pests (imago stage), which during spraying hide in secluded places - leaf axils, inside a deformed leaf blade, will also not be affected - the solution will not affect them. If you wet the leaves poorly, then they will not even get drunk on the poisonous part of the leaf. The problem with castor fever is that the drug does not have a systemic effect - it does not penetrate deeper into the leaf. I.e. if the sheet is moistened only from above, and the solution does not get on the back side, this part of the sheet remains defenseless.
You can expect good results from castor oil if you have thoroughly sprayed the whole plant, small indoor flowers can be completely dipped into the solution. We can say that the drug is completely useless for spraying plants (varieties) with curly leaves, for example, ficus baroque, or if the leaves are very deformed, for example, the bitten tops of branches in raspberries should be treated by dipping in a bucket of solution, and not trying to spray.
Plus, the undoubted advantage of the drug Kleshchevit in its low toxicity - it is destroyed on the leaves 2-3 days after processing, and in the fruits of vegetables after 2 days. This means that it can be used to spray homemade fruit lemons, vegetables and berries in the garden 3 days before harvest.
Do not use Kleschevit more than three times increased resistance (each time the percentage of survivors is increasing).
It was found that the effectiveness of the insecticide against spider mites is greatly influenced by air temperature, for example, the drug is maximally toxic at a temperature of 30-32 ° C, more or less effective in the range from 24 to 26 ° C, and is not effective at temperatures below 20 ° C. The explanation is simple - the cycle of tick development at high temperatures accelerates, most of the feeding individuals manage to fall under the influence of the drug.
Compatibility in tank mixtures
Castor fever is compatible with insecticides from the classes of organophosphates (fufanon, actellic) or pyrethroids (talstar), while each of the drugs must be used in a dosage half the recommended one. Mismatched with the insecticide vermitek (the same class of avermectin). It is advisable to use castor in alternation with drugs of biological origin, such as bitoxibacillin.
Also, castor is compatible with any growth regulators (zircon, epin, ribav-extra) and fungicides that do not form an alkaline solution reaction.
Toxicity
Castor fever has hazard class 3 (moderately dangerous substance), hazard class 2-3 for bees (class 2 in an increased dilution dosage against aphids). Castor is not phytotoxic.
