Miscellaneous notes (pp. d5-dS).—rhyto2)ltthora infesians injured the 

 leaves and fruit of tomatoes in 1890 in several parts of Connecticut. In- 

 juries to the leaves by Cladosporiumfulvum, and to the fruit by Mairospo- 

 Hum tomato, Cke., and by Fusarium lycopersici, Sacc, are also reported. 

 A destructive epidemic was observed amoug the tomato worms {Plileije- 

 tliontius Carolina and P. celeus) infesting a tield in the vicinity of Xew 

 Haven. It was found that this was caused by the fungus '■'-EmpuHa (/njlli, 

 form aiilic(v, which is common on hairy catei[»illars aud has also been 

 found this year on a nuuiber of naked cutworm larva- {Lithopliane, 

 Mamestra, aud Agrotis). It was found easy to propagate it on young 

 tomato worms, which died after the usual period ot incubation (G to 10 

 days) with the characteristic symptoms." Another species of Emini.sa 

 was very destructive to the grape leaf hopper {Typhlocifha ritis) in a 

 vineyard at Meriden and was jilso found at New Haven on the cabbage 

 worm (Picris rapa'), on wiiich insect it was successfully bred at the sta- 

 tion. "What ai>pears to be the same IJnipKsa has kindly been sent 

 from New Jersey by Professor lialsted, on Picris larva-, and the same 

 fungus is reported to have killed vast numbers of the clover weevil in 

 that locality during the past season." 



Peronospora rubensis was observed on cucumbers at South Man- 

 chester, Connecticut. 



The mildew of lima beans (Phytophthora phaseoU), described and illus- 

 trated in the report of the station for lS8i>. i)age 107 (see Experiment 

 Station Eecord vol. ii, p. 482), was again destructive in 180(», making 

 its appearance in a number of localities in Connecticut. Several varie- 

 ties of pears of the Japanese strain have shown themselves very 

 susceptible to injury by a rust {Gymnosporangiuni ylohosum) derived 

 from the red cedar. Tliis rust is also found on ai)[>les, quinces, etc., in 

 Connecticut, but does not attack the ordinary varieties of pears. 



" A mildew, which appears to be the form described by Peck as Ram- 

 ularia rufomacnlnns on anothermember of the same family {Polyynnacea'), 

 has been observed in several localities on buckwheat." 



A clover rust referred to in the Annual Keport of the station for 

 1889 as caused by Uromyces striatns, proves to be U. tri/olii, Wint., 

 and was very abundant in 1SI>0, 



Piiccinia rubigo vera, D. C, aud Urocy.siis occulta, Kabh., were very 

 common on rye in 1890. 



Some results from the application of fungicides (pp. 99-104). — Success- 

 ful experiments are reported with Bordeaux mixture and ammoniacal 

 carbonate of copper for leaf spot of quince {Entomosporiiim maculatum, 

 Lev.), black rot of grapes, anthracnose of grapes, and strawberry rust; 

 and with Bordeaux mixture for leaf spot of [.lums and eherrios and 

 potato blight. The effect produced by the treatment with Bordeaux 

 mixture for the leaf spot of quinces is strikingly illustrated in two plates
