Miticidal properties

The miticidal property of tetranactin in the fields of apple and tea had been evaluated in Japan since 1968, and tetranactin has been used as a miticide for plants since 1974. 

Formamidine insecticides are all derivatives of formamidine (HN=CHNH,). This class comprises a new, small group of chemicals that exhibit insecticidal and miticidal properties. Three examples are chlordimeform, formetanate hydrochloride, and amitraz, shown as follows. 

The miticidal properties of some isothioureas may be due to a controlled release of the effective carbodiimide. An N-sulfonylcarbodiimide can be used as a masked oral... 

Optimization of biological properties in a series of miticidal and mite ovicidal 2-aryl-l,3-cycloalkanediones, Ia,b, and enol esters, II, was achieved through analog synthesis and testing supported by the development of quantitative structure/ activity trends during the course of the project. QSAR equations developed during an initial phase provided the basis for both... 

Summarizing, the use of natural products as miticides in apiculture, with the exception of some substances, is not widespread. In extensive laboratory tests many compounds showed significant acaricidal properties. However, very few of them have proven to be effective when applied in field trials. Considerable variations in local environmental and colony conditions can affect efficacy. In case of mixtures, such as essential oils, the difficulty in obtaining standardized compounds also affects treatment predictability. Nevertheless, identifying new acaricide compounds with low toxicity to honey bees is fundamental for providing candidate compounds for field trials. Furthermore, the development of... 

Dinitrophenols are used as fungicides, herbicides, or insecticides. The fungicidal, herbicidal, or insecticidal properties depend on minor differences in the chemical structures of the different dinitrophenol compounds. Several dinitrophenol compounds have more than one pesticidal use. The pesticidal use of one dinitrophenol, dinoseb, was eliminated in the United States in 1986. There has recently been a voluntary cancellation of all US product registrations for the fungicide/miticide Dinocap.
