Thinking about an aircraft, the first thing to strike  is the scenic  view from the plane, comfort , and the easy but fast rushing through the air without any bumps, the fascinating buzzing sound, the soothing service and the beauty of nature.

This was one merry part of an aircraft system; let us take a look on rodentone of the segments of the other side of the system say an aircraft arrestor system.

Wondering what an aircraft arrestor system does?

While emergency landings or while rejected take – offs , we make use of  an Aircraft barrier/arrestor system which is installed at the end of the runway to stop the forward movement of an aircraft overshooting the runway so as to cause minimal damage to the aircraft or contusion to the crew.

When in motion aircraft develops an emergency, the aircrew has to decide if they need to use the arresting system. If needed, the pilot deploys the aircraft’s hook, and lands the plane at least 1,000 feet from the arresting system.
The hook drags on the surface of the runway until it comes in contact with the 1.25-inch steel cable. Once the aircraft’s hook captures the cable, the cable rips the nylon cords, holding it flat on the runway, and unravels its attached nylon tapes from storage reels.
As the tapes are unraveled, the reels turn a hydraulic pump that applies pressure to a set of modified brakes.

It is these brakes that bring the aircraft to a stop, small pieces of nylon rope are used to hold the cable flat on the runway, the aircraft arresting system is important because it is the only safe way of stopping an aircraft with only a minimal amount of damage while preventing the loss of its crew.

Each time the system is used the nylon tape must be inspected and rolled back onto its storage reels. The cable is then returned to its home at the start of the runway and tied down with nylon rope.

Arrestor barrier system is therefore essential. The barrier is lifted with the help of a system on the command received by remote control.

The aircraft arrestor system remains in open ground all the time, since it is used on runways. It is damaged by rodents who by nature chew and cut materials as they need to sharpen their continuous growing two pairs of incisors and hence the nylon tapes in open fields are prone to these rodent attacks. The rodents consume more than 50% of the nylon belt without any anti-rodent additive.

This is a serious issue which needs to be noticed and addressed immediately to provide better protection to the arrestor system indirectly benefiting the aircraft.

Rodents are mammals who are intelligent, social and can gnaw all time. They are attracted to the polymers due to their aromatic odour,attractive colour and smooth texture of the polymeric product. They have left their imprints on essential sectors such as Agriculture, Railways, Defence, Telecommunications, Gas Sector, Heritages etc.

They chew onto to the polymeric, plastic substances passing through every possible gap.

At present no measures have been taken in hampering the movement of these sneaky rodents in the aircraft arrestor system.

Application of conventional methods like rodenticides kills the target as well as the non-target species. They have high release mechanism which can leach out and pollute the air, water and soil. They pose a serious effect on human health as well.

These factors have led to the search of a non- carcinogenic, non-hazardous, non- mutagenic product for protection against the effect of these rodents.

Such a product is manufactured in India by CTech Corporation. Combirepel™ is an extremely low toxicity, non-carcinogenic and non-mutagenic, non- hazardous, non- dangerous and environmentally safe animal anti rodent aversive. CombirepelTM is consumed globally for myriad applications. It is a product resulting from smart technology and green chemistry.

CombirepelTMcan be incorporated in the nylon belt which would keep the rodent away and prevents the chewing of threads and keep the area rodent free.

CombirepelTMdoes not kill the rodents it just keeps them away by making use of sensory mechanisms. It is non-toxic to rodent as well humans.

CombirepelTM is compatible with all kinds of thermoplastic and thermosetting polymers such as PE, XLPE, PP, PVC, polyesters, epoxies and paints: both water and oil based. Combirepel™ is available in the form of solid masterbatch, liquid concentrate and lacquer.


spider miteHey!are you coming for the party? Oh yes definitely I have visited that place before , it’s awesome  and a great spot the whole place will be available for us to party, eat, have fun and chill . I am excited to reach the venue, meet you there at night Bye!

This is the conversation between mites and the party is held at poor farmer’s farm.

A mite is teeny-weeny and itty-bitty yet catastrophic. Mites, along with ticks, are small arthropods belonging to the class Arachnida. In soil ecosystems, mites are favored by high organic matter content and by moist conditions, wherein they actively engage in the fragmentation and mixing of organic matter.

Mites are among the most diverse and successful group of all the invertebrate groups. They have exploited an incredible array of habitats, and because of their small size (most are microscopic), they go largely unnoticed. Mites occupy a wide range of ecological niches.

Termite colonies eat nonstop, 24 hours a day, seven days a week! This results in up to $ 2 billion damage in every year.

Most mites are difficult to see clearly without magnification. However their movement across a surface can sometimes be detected. Some species of plant feeding mites produce webbing and silk like the spider mites. They also can cause discoloration of leaves and eventually leaf drop. Other mites like the clover mite can easily be seen due to their bright red colouration.

Spider mites are less than 1 millimeter (0.04 in) in size and vary in color. They lay small, spherical, initially transparent eggs and many species spin silk webbing to help protect the colony from predators,they get the “spider” part of their common name from this webbing.

Hot, dry conditions are often associated with population build-up of spider mites. Under optimal conditions (approximately 80 °F or 27 °C), the two-spotted spider mite can hatch in as little as 3 days, and become sexually mature in as little as 5 days. One female can lay up to 20 eggs per day and can live for 2 to 4 weeks, laying hundreds of eggs. This accelerated reproductive rate allows spider mite populations to adapt quickly to resist pesticides, so chemical control methods can become somewhat ineffectual when the same pesticide is used over a prolonged period.

Thus the quick reproductive cycle of spider mites accelerates the number of mites attacking the field, farm, crops.

Spider mites generally live on the undersides of leaves of the plants, where they may spin protective silk webs, and can cause damage by puncturing the plant cells to feed. Spider mites are known to feed on several hundred species of plants. They attack a wide range of plants,including peppers, tomatoes, potatoes, beans, corn,strawberries, etc.This leads to a vast amount of damage to the crops, farmer, nation and economy.

So getting rid of spider mites is of top priority in an infestation. In the world of horticulture there are mites and then there are spider mites, or what we can call the two-spotted mite.

Warm, dry temperatures make the perfect climate for the spider mites reproductive cycle, which leaves plants susceptible not only to drought but also to the mite’s tenacious appetite.

The natural method of protection from mites like the application of Neem oil, insecticidal oil ,may provide control, when combined with a suitable surfactant and diluted with water but a continuous repeated application is required therefore it is not that resistant to mites.

Acaricides, Insecticides, Miticides are applied to crops to control spider mites.  Disadvantage associated with this includes toxicity, and the resistance to all the mite species even the useful ones are resisted.

Pesticides don’t work on the mites as they have adapted to them. Usingapesticide will only kill off the beneficial bugs that eat spider mites, which will only make the spider mite infestation worse.

Spider mite damage can not only make a plant look unsightly, it can even kill the plant.

It is important to use such a product which would not damage the crop yet keep way the insects and mites. A product which is non-hazardous, non- carcinogenic, non toxic.



Combirepel™- anti insect additive a CTech Corporation product is an ideal solution for the prevention of attack of termites and other insects.

It is made from combination of green practices and best of chemistry to give environmentally safe product .It is being used worldwide for a myriad of applications.

CombirepelTM does not kill but only keeps away the insect by making use of sensory mechanisms. Aggressive species are further deterred from attacking by advanced mechanisms like aversion, feeding deterrents , mating disruption, reproduction cycle inhibition, growth impairment and chemo sterilization thus modifying their response towards the CombirepelTM containing products resulting in them staying away from the application.


The active life of CombirepelTM ranges from 5-40 years and it is on an average found to be effective for 15 years. Since CombirepelTM is designed to averse effectively and not kill the insects, it doesn’t harm the target as well as the non target species in any way. It is RoHS, RoHS2, REACH compliant and FIFRA exempted.

We believe in repelling and not destroying.
