Twelve-spotted cucumber beetle on cabbage, Mississippi (quoted report)

The Insect Pest Survey Bulletin (U.S. Bureau of Entomology) · Vol. 5, No. 1, pp. 31-32

R. W. Harned (March 25): Mr. Wedgworth has observed the 12-spotted cucumber beetle in large numbers on cabbage plants during February and March in Warren, Hinds, and Copiah Counties. His first report in regard to the abundance of these insects on cabbage plants was dated February 10. In regard to the injury caused to cabbage by these beetles, he writes as follows: "This pest may feed on any part of the leaf, but seems to prefer the under side. However, I have watched them feed for some time on the upper surface, and sometimes holes are eaten through the leaves. I have examined about 20 cabbage fields or about 60 or 70 acres and found this pest present in every field. I believe I am safe in estimating the damage at 1 per cent of the crop. In one field, at Yokena, the damage ran up to about 5 per cent or better. The principal injuries are, first, buds eaten out, heads will not form; second, attack on the young plants often means death to the plant, causing a poor stand."

Report, Raymond Branch Experiment Station, 1925 (includes quoted report by Wedgeworth)

Mississippi Agricultural Experiment Station Bulletin · Bulletin 231, pp. 12-17 (his quoted report begins p. 12)

Several tests of various natures have been conducted on and around the Station that will be of especial interest to the trucking section. Mr. H. H. Wedgeworth of the State Plant Board, cooperating with the Station, had charge of this work. A part of Mr. Wedgeworth's report follows: POISONED-BAIT FOR THE CONTROL OF CUTWORMS. "During the spring of 1925 about 15% of the tomato plants were cut by cutworms in the Crystal Springs trucking section, and many other crops were also attacked. In many fields where no control measures were taken losses of from 75 to 90% were sustained."

Macrophoma phaseoli in Mississippi (quotes his letter of Sept. 29, 1926)

The Plant Disease Reporter · Vol. 10, No. 9, p. 120

After making inquiries concerning this reported Mississippi occurrence the following statement from H. H. Wedgworth of the Mississippi Experiment Station, in a letter of September 29 to W. A. Whitney of the Bureau of Plant Industry, has been received. This is the first direct report of this disease from Mississippi. The fungus was identified by C. A. Ludwig on specimens sent to him by Wedgworth from Mississippi. "Beans infected with a stem rot and having fruited bodies very similar to Macrophoma phaseoli have been collected from two fields in Oktibbeha County and from one field in George County. The disease was quite destructive, especially in one field this year. This particular field in Oktibbeha County suffered a loss of about 60 or 65 per cent of the plants from the spring planting. Unfortunately, the grower planted this field to fall beans and the disease has been prevalent in this planting also to the extent of about 50 per cent."

Apple scab, Michigan

The Plant Disease Reporter · Vol. 13, No. 3, p. 35

Michigan: Ascospores began discharging from the perithecia on the old leaves in the southern part of the state about March 21, in the central part about April 5, and in the northern part of the lower peninsula about April 9 and are still being discharged in all parts of the state. The first new scab lesions were collected from an unsprayed orchard near Fennville on May 6 and are very abundant at the present time on unsprayed and improperly timed sprayed orchards in all parts of the state. Infection on the young fruit was first noted on June 3 in an orchard in which nearly ten per cent of the fruit showed from one to five lesions. The indications are that Michigan will have a very severe scab year. Excellent control of scab has resulted in orchards where the sprays have been properly timed. (Wedgworth, June 5)

The Plant Disease Reporter · Vol. 13, No. 3, p. 37

Michigan: The cool, wet weather prevalent during the past few weeks has been very favorable for leaf curl infection. The extremely wet weather during the early spring prevented the spraying of many orchards for curl and the results are that leaf curl is unusually severe. About 75 or 80 per cent of the leaves in unsprayed orchards are badly infected with this disease. (Wedgworth, June 5)

MICHIGAN CHERRY DISEASES. The following notes were contributed by H. H. Wedgworth, Michigan Agricultural College, June 24. Brown rot (Sclerotinia fructicola). Caused considerable blossom blight and twig blight early in the spring. It is now very severe in all neglected orchards. Seventy-five to 90 per cent of the fruit being attacked in some instances. Leaf spot (Coccomyces hiemalis). A large percentage of the leaves are turning yellow and falling from the trees in the unsprayed orchards in all parts of the state. Although the disease is very severe, it is not causing defoliation of the trees as early as it did last year. Properly sprayed orchards are practically free of leaf spot at this time.

Weather conditions continue to be very favorable for this disease in Michigan. It is causing severe damage to the blacks and purples in most sections of the state. Its attack on the fruit has caused heavy losses in some cases. Powdery mildew (Sphaerotheca humuli). Several fields have been noted in which this disease is very severe in Michigan. In some instances the leaf tissues have apparently been killed from the attack of mildew.

Winter injury to peaches in Michigan (with Fig. 4 map)

WINTER INJURY TO PEACHES IN MICHIGAN. Although an extensive survey of the state of Michigan has not been made to determine the exact amount of injury caused by the sub-zero weather of January 18, it is believed that enough observations have been made to indicate the relative extent of the injury. The accompanying map gives the relative distribution of the injury in the state. ... It should be noted that the severe injury has occurred in Berrien and Van Buren Counties which include more than one-half of the Michigan peach industry. The aggregated losses from this freeze will amount to more than $1,500,000 to the peach industry of this state. (H. H. Wedgworth)

Michigan: Apple leaves collected on February 24 in Ionia County were placed in a moist chamber in the laboratory where ascospores were matured in 44 hours. The perithecia were very abundant on most of the leaves collected. The unusually warm weather which has prevailed during the past nine or ten days is no doubt the cause of the advanced condition of the fungus. (H. H. Wedgworth, Feb. 26)
