This would throw harvest of the croc into the frost period in fall. Beet Leafhopper Moves To Utah Beet leafhopper movement into the agricultural areas of Utah is now underway, according to studies stud-ies being conducted by U. S. Bureau Bur-eau of Entomology and Plant Quarantine entomologist H. E. Dorst, of the Utah Agricultural Experimental Station staff. Double hill planting of tomatoes has been shown to be profitable. It provides a means of reducing losses los-ses when the leafhoppers are abundant. abun-dant. This planting method is accomplished ac-complished by placing a plant at the opposite edges of the shovel blade during hand planting. In the case of machine planting, doubling the stand within the rows also reduces re-duces losses, Utah State Agricultural Agricul-tural College scientists indicate. Insecticide applications have not protected susceptible crops from this pest, entomologists Dorst and W. E. Peay have found. However, the increase in stand of tomato plants in commercial fields and home gardens does assure the growers a better chance of producing pro-ducing a profitable crop. Even in years when leafhoppers were scarce, double hill plantings have increased yields by 2 to 5 tons per acre. This has more than paid for the extra plants and labor, the |
