The next major discovery in this field, which was the result of a joint research effort in 1968 between M and T Chemicals, Inc., and the Dow Chemical Company in the United States (475, 524), was that tricyclo-hexyltin hydroxide ("Plictran ) possesses a very high activity against certain types of mites, and this compound was subsequently introduced by Dow as an acaricide for use on apple, pear, and citrus-fruit trees. A second triorganotin acaricide, bis(trineophyltin) oxide ("Vendex or "Torque ), has recently been introduced by Shell Chemical Company (476). Two other tricyclohexyltin compounds are currently under de-...

Plictran (tricyclohexyl tin hydroxide), (TCHH), is an organotin most generally used as a miticide for fruit trees and ornamental trees and shrubs. It was developed and is produced by Dow Chemical Company and sold as a 50% wettable powder acaracide, or 50% TCHH-50% inert diatomaceous earth. It is light tan in color and has a negligible vapor pressure (3). 

Reagents. The chemicals used in this study were concen-trated HCl, concentrated H2SO4, concentrated HNO3, concentrated NHi,0H, 10% v/v HNO3, 3% v/v HCl, CuC12 2H20, 1000 ppm Fisher Certified AAS Tin Reference Solution, and Plictran. ... 

HOUR AND BEAULIEU Breakthrough Studies with Plictran... 

Data Treatment. The experimental design of sample collection did not permit statistical comparison of the collection efficiencies of filter combinations versus concentrated HNO3 impingement. The laboratory chamber was designed to simulate field conditions and not provide a "closed" system in which the concentrations of Plictran could be controlled. 

The large breakthrough of Sn to the back-up impingers in all cases but one was a concern. Each impinger in this case contained only 10 mL of acid. With filters in contact in a cassette and both filters ashed at the same time in a beaker, it could not be determined if any Plictran was breaking through the filters. To answer that question, the filters were separated as described.

Trialkyltin compounds have been shown to be effective agriculturally. Tributyltin oxide (III) has insecticidal and fungicidal activity, but generally has not been useful for plant protection due to phytotoxicity and volatility problems. Tricyclohexyltin hydroxide (TCTH, IV) has been an extremely effective acaricide.(3) Developed under the trade name Plictran, this compound was one of the first commercial acaricides. Another trialkyltin compound under development is hexakis (jS > j3 -dimethylphenylethyl)distannoxane (Vendex, V), which is also an effective acaricide. 

In jiingerer Zeit brachte die Dow Chem. Corp. unter dem Namen Plictran ein Praparat auf den Markt, das als Wirkstoff Tricyclohexyl-zinnhydroxid enthalt. Mit diesem Mittel ist eine Bekampfung der sehr resistenten Spinnmilben moglich. 

Successive resistances have driven control of the Boophilus cattle ticks all the way to OP compounds, and from them to chlor-phenamidine (chlordimeform) although it has been recently found that carbaryl is effective in cattle dips if synergized with piperonyl butoxide. The two-spotted mite has gone through a fantastic sequence of acaricides, the only ones to which resistance has not yet been reported being Pentac and the organo-tin compound Plictran. 

Another agricultural development of great potential interest is based on the more recent observation that certain rather unusual triorganotin compounds have considerable acari-cidal activity. Well-known at present is the compound tri-cyclohexyltin hydroxide (trade name "Plictran") developed by Dow Chemical Company and M T Chemicals. This compound is very effective against spider mites in fruit orchards and has been found to act as well against varieties of spider mites which had developed resistance towards the usual acaricides based on organic phosphorous compounds and car-...

Branching at the a-carbon atom appears to confer enough steric hindrance to inhibit dehydration of the hydroxide. Tricyclohexyltin hydroxide, which is used as an acaricide under the name of Plictran, is stable up to about 125 °C when it loses water to give the oxide.3 Tri-t-butyltin hydroxide can be prepared from tris(di-t-butyltin oxide) as shown in Scheme 12-1, and loses water to give bis(tri-t-butyltin) oxide only when it is heated for several horns under vacuum at 200 °C. The properties of some triorganotin hydroxides and oxides are given in Table 12-1.15... 

Triphenyltin hydroxide (Fentin) and triphenyltin acetate (Brestan) are used to combat potato blight, leaf spot on celery and sugar beet, rice blast, and coffee leaf rust. Tricyclo-hexyltin hydroxide (Plictran), bis(trineophyltin) oxide (Vendex or Torque), and 1-tricyclohexylstannyl-l,2,4-triazole (Peropal) have also been used for the contol of mites on apples, pears, and citrus fruits.
