Definitions

• Nitrophenyl carbonates devoid of cyano substituents are known and have pesticidal activity.
• 3,287,611 discloses compounds of structure where R is lower alkyl and these compounds have acaricidal activity.
• US. 3,234,260 discloses similar acaricidal compounds which are further substituted in the phenyl ring.
• U .8. 3,198,824 discloses as fungicides and herbicides compounds of structure where R is alkyl and Ar is aryl.
• the compounds of the invention can be prepared by phosgenation of. the compound NC -R --0H giving NC-R O'CO--Cl and then reacting this compound with a dinitro-alkylphenol.
• the same type of compounds can be obtained by reaction of the appropriate chloroformic acid with the appropriate phenolate.
• the wettable powders contain 50-90 weight percent of the active compound and for the rest a dispersing agent, a wetting agent, and a carrier. If the active compound is a liquid or oil, the content of active compound is below 50 weight percent. The liquid compounds are then adsorbed on adsorbing carriers.
• Emulsifiable solutions can be obtained by the solution of the active compound in a solvent or mixture of solvents. Suitable solvents are alcohols, ketones, ethers, aromatic hydrocarbons and petroleum fractions.- As indicated, dispersing agents, wetting agents, or emulr sifying agents can be added. 0

• Example III The examination of the acaricidal action was carried out on mites of the genus -Bryodia on leaves of the brown bean. Leaves were sprayed in petri dishes with aqueous formulations of the active compounds in concentrations of 200, 40, and 8 p.p.m. in a quantity corresponding to 1,000 liters per hectare. Before the leaves were sprayed 25 living mites were present on each leaf. Tests were carried out in quadruple.; after 1 and 2 days the dead mites were counted.
• R is a secondary amyl group and R is CI-I CH CN.
