Korean Vegetables Do Well in 

 New Hampshire. Of 145 kinds and 

 varieties of Korean vegetables grown 

 in test plots, several were outstand- 

 ing for their earliness, good quality, 

 and adaptability to a northern cli- 

 mate. 



An Oriental variety of table soy- 

 bean, which has been named Pando, 

 matured green shell beans in 78 days 

 on compact plants about one foot 

 tall. The pods ripened rather uni- 

 formly. 



One variety of eggplant proved 

 early and extremely productive. The 

 black fruits are long cylindrical in 

 shape. Single plants matured 10 

 to 12 fruits before frosts. This var- 

 iety is being called Korean Long. 



A Japanese watermelon variety 

 called Shingyamato matured high- 

 quality, 10-pound melons both at 

 Durham and in Coos County, where 

 a crop of this kind seldom ripens. 

 Selections of this have been named 

 Colebrook after the place where the 

 variety was first grown in America. 

 The sweet, crisp flesh of these water- 

 melons is red and the seeds are small 

 and black. 



Early muskmelons and cold-re- 

 sistant, early-ripening cucumbers al- 

 so proved promising and can serve 

 as valuable sources of breeding ma- 

 terial for improved, early vegetable 

 varieties.

Weed Control 



2,4-D not a Cure- All. 2,4-D, a 

 selective weed killer, is selective not 

 only with crops, but also with weed 

 species. Tests made in 1948 indi- 

 cated that mustard and white pig- 

 weed (two of the most common 

 weeds in oat fields) are easily con- 

 trolled by spraying with I/2 lb. or 1 

 lb. of 40 per cent 2,4-D acid per 

 acre, but that certain other weeds 

 were not killed by the spray. At 

 these concentrations, young clover 

 plants survived, although they re- 

 acted to the 2,4-D. The use of this 

 substance to control weeds in oats 

 at these low rates of application is to 

 be recommended, especially where 

 mustard-like plants and white pig- 

 weed are in abundance. 



When these rates of 2,4-D were 

 applied to corn, either as a pre- 

 emergence or post-emergence spray, 

 mustard (kale, charlock) and white 

 pigweed were controlled, but red- 

 rooted pigweed, ragweed, and smart- 

 weed were not killed. Hence, the 

 plots of corn which were not culti- 

 vated, but sprayed only, exhibited a 

 high weed population of these species 

 that were resistant to the herbicide.

Work is being continued during 

 1949 with 2.4-D at higher rates of 

 application. Meanwhile, and until 

 more information is obtained in our 

 climate and on our soils, our advice 

 to farmers is not to throw their culti- 

 vators away, but to use 2,4-D spray- 

 ing as a supplement to normal culti- 

 vation procedures. 



At rates of 1/2 lb., 1 lb., and l^/o 

 lb., of 40 per cent 2,4-D acid per 

 acre, potato vines were noticeably 

 affected, yields were reduced slight- 

 ly; but potatoes sprayed at the lower 

 rates showed a higher specific gravi- 

 ty in the tubers than those from un- 

 treated vines.

Gray Birch in Blueberries Can Be 

 Killed by Spraying. Gray birch is 

 one of the most troublesome weeds 

 in the low-bush blueberry fields, and 

 is difficult to eradicate because of 

 its ability to sprout from the stumps. 

 In an experimental plot of three 

 and one-half acres that was literally 

 covered with gray birch varying in
