Outside of the United States, fenvalerate is used on cotton (Gossypium hirsutum) in Australia, Greece, and South Africa, and on apples (Malus sp.), pears (Pyrus sp.), and potatoes (Solarium sp., Ipomea sp.) in Canada (Reed 1981) uses in other countries, including Mexico, are anticipated (Reed 1981), as is increased use against agricultural, poultry, dairy, and household pests (Mumtaz... 

Occurs in apples -Malus pumila and Pyrus communis... 

Spring beauty Apple, pear, and plum trees and their ornamental relatives In the genera Malus, Pyrus, and Prunus are some of the first trees to blossom In spring, usually flowering In profusion. This provides a welcome treat not only for the gardener, but also for hungry flying Insects such as bees that have ventured out early In the year. 

Wardrop (13,14) examined sclerenchyma fibers of Liriodendron tulip-ifera and sclereids of Pyrus communis, previously fixed with KMn04, and concluded that the vesicles supplied their contents to the cell wall, though the origin of the vesicles was not established. As discussed before, however, permanganate fixation is undesirable for these cytological observations.

If the structure of a GA can be inferred from its mass spectrum the suspected compound may be synthesized and its mass spectrum compared with that of the unknown. Thus the structures of GAlj.6 and GA y were confirmed by the partial synthesis of their methyl esters from GA4 (38). This synthesis will be discussed in detail later. GAM was identified in immature seeds of Pyrus communis (pear) in an analogous manner by comparison of its mass spectrum with that of a product obtained from incubating ent-15 -hydroxykaurenoic acid with a mutant of the fungus G. fujikuroi (29). 

The Bl-tla mutant was found also to metabolize ent-lfo-hydroxy-kaurenoic acid to a number of 150-hydroxylated GAs (J.R. Bearder K. Kybird, unpublished information), one of which, 58-hydroxy GAg., was subsequently identified as a new GA, GAl, in seeds of Pyrus communis (39) ...
