FUMIGATION. 



State Entomologist W. G. Johnson in his report referred to the 

 fumigation of nursery stock, and stated that thirtv-four fumigation houses 

 are now in oj^eration, and others being constructed. The provision of the 

 law making it compulsory was inserted by the nurserjonen themselves, 

 and the increased sales resulting from it have shown its advisability. In 

 the forty-six nurseries of the state there are over 4,000,000 standing fruit 

 trees and 30,000,000 small fruit plants. The new bud mite which has 

 l^een so destructive to peach nursery trees was described and specimens 

 of its work exhibited. The San Jose scale was reported under control 

 in the nurseries, and occurring in one hundred and forty-one localities 

 throughout the orchards of the state. A new insect, probably of the 

 genus Dactylopius, has been found injuring the roots of the Kieffer pear 

 quite seriously. 



State' Pathologist C. O. Townsend reported that during the season 

 some three hundred orchards, aggregating over 500,000 trees had been 

 inspected for yellows, and all infested trees had been or were being 

 removed. The peach rot has been very destructive the present season, 

 causing a loss of about one-fourth of the crop. Peach-leaf curl, pear 

 blight and apple scab were reported as doing considerable damage. The 

 fact is that Maryland growers have not properly appreciated their friend 

 the spray pump, and fungous diseases have in many cases gained the 

 upper hand. — Maryland Hort. Soc. — Country Gentleman. 



WIXTER SPRAYUs^G FOR PEAR INSECTS. 



Two of the most common and injurious insect pests of the pear tree 

 may be largely controlled by a proper spraying while the trees are 

 dormant during the winter. 



PEAR-LEAF BLISTER MITE. 



One of these is the pear-leaf blister mite. The reddish blister which 

 appear on the leaves in spring and later on turn brown and become thick 

 and corky, do not seem to l)e a serious injury to the tree, other than in
