Maher Fenpyroximate (5% SC)
The mechanism of action:
Fenpyroximate is an acaricide that primarily has a contact effect. It also has a digestive tract and high intrusive properties. This pesticide affects larvae, nymphs and adult tick of two-legged and four-legged (quadruped) of plant pests and prevents the transmission of electrons in mitochondria, which has a severe impact on all stages of life (excluding eggs) and prevents nymphs from molting. Also, this poison can disrupt the nutritional behavior of the ticks. In addition to the above-mentioned, fenpyroximate can inhibit oviposition of mother tick and reduce the egg population and the following nymphs.
Uses of fenpyroximate:
In addition to the effect of the weakening of the growth of tick eggs, fenpyroximate completely eliminates the stages of nymphs and puberty. However, in order to achieve a definite success against all biological processes, mixing it with an acaricide with ovicide effect like hexythiazox is inevitable. The consumption of fenpyroximate at the beginning of the season reduces the number of nymphs. The adult mite begins its activity at the time of the swelling of the bud, which at the same time fenpyroximate consumption decreases oviposition. It should be noted that the spraying of this poison in the flowering stage should be avoided, as it may cause sterility of the ovary. Recommendation of fenpyroximate for nymphs and puberty stages of mite varieties is often 0.5-1.0 per thousand, but the addition of 1% of super oil increases the effectivity of this acaricide as far as possible. The use of this compound on the sensitive stages of the mites causes the consumption of this compound to be reduced. The use of this acaricide should be avoided consecutively during a crop season as it may result in resistance to this acaricide. Therefore, the use of this acaricide once or twice if necessary (preferably with the advice of a botanical expert) during one crop season is recommended. Also, it should be taken into account that the use of another acaricide which has the same mechanism of action on the mite, may increase the likelihood of resistance to this compound. It has a good insecticide effect, which also controls leafhoppers, mealybug, and psyllas, in addition to mites. The consumption of fenpyroximate in the recommended dose causes the death of the mite and its consumption at lower doses, which can disrupt the nymphal molting.
Adaptation and mixing of fenpyroximate:
The use of fenpyroximate in recommended doses does not have any adverse effects on the plants. It also can be mixed with all common acaricides.
