AbstractSince 1970 the increasing level of Colorado potato beetle infestation in southwestern Ontario has necessitated foliage sprays or planting treatments with systemic insecticides. Spray tower tests of many insecticides against eggs, larvae, and adults indicated that the best overall materials would be carbofuran, azinphos-methyl, and chlorfenvinphos.At planting time furrow treatments with granular carbofuran, disulfoton, or phorate demonstrated good control of all potato pests until the end of June. After that time only the carbofuran and phorate treatments gave protection against a heavy second generation of potato beetles. Yields were related to the degree of pest control.

Cultural Requirements

Broccoli (Brassica oleracea var. italica), a popular vegetable crop, has one of the most exacting climatic and cultural requirements, which limit its commercial production to a few favored locations. A field experiment was conducted at Mizoram University, Tanhril, Mizoram during winter of 2013/2014 to find out the effect of time of sowing on plant performance and yield of broccoli. Six sowing time was done viz. 17 October (T1), 24 October (T2), 31 October (T3), 7 November (T4), 14 November (T5) and 21 November (T6) with plant spacing of 45cm x 45cm. Yield and yield contributing characters were significantly influenced by the planting time. Highest average weight of marketable curd per plant (199.20 g) was obtained from T2, whereas lowest average weight obtained from T6 (75 g). The influence of planting time also showed significant difference on the calculated yield (tonnes per hectare) of broccoli, in which T2 showed highest marketable yield of 9.83 t/ha.

Cut Seed

Shoots of the early-maturing potato (Solatium tuberosum L.) cultivar Jemseg often do not emerge uniformly when cut seed pieces are planted in cold soil. Under controlled temperatures of 10, 15 and 20 °C, shoots from whole tubers and basal portions of Jemseg tubers emerged later than those from apical portions of seed tubers. The delayed emergence of the basal portion was most pronounced at low temperatures and ranged from 5 to 17 d. Emergence from basal vs. apical portions of Conestoga was delayed by 10 d at 10 °C and by 4 d at 15 °C, only when seed tubers with a single dominant apical sprout were used. There was no delay at 20 °C. The variable time to emergence of shoots in the field can be explained by delayed emergence from basal buds on cut seed pieces.Key words: Potato, cultivars, emergence, bud position, temperature, seed tuber

Laboratory and field-cage studies were conducted in Texas in 1965 to evaluate treatments of the systemic insecticides, Azodrin (3-hydroxy-N-methyl-cis-crotonamide dimethyl phosphate), Bidrin (3-hydroxy-N, N dimethyl-cis-crotonamide dimethyl phosphate), American Cyanamid CL-47031 (cyclic ethylene (diethoxy-phosphinyl) dithioimidocarbonate) and Temik (2-methyl-2-(methylthio) propion-aldehyde O-(methylcarbamoyl) oxime), applied incorporated in lanolin to the stems of cotton plants against Heliothis zea (Boddie) and H. virescens (F.). Reductions in numbers of developing larvae of H. zea were substantial on individual plants the stems of which had been treated with Azodrin or CL-47031 and which were artificially infested with eggs. When first-instar larvae of H. zea or H. virescens were caged on plants 3, 7 or 14 days after stem treatment with 2.5, 5.0 or 100 mg. Azodrin, Bidrin or CL-47031 per plant, net mortalities ranged from 21 to 80 per cent after three days. The mortality of adults of H. zea provided with sucrose solutions containing 1 p.p.m. of the systemic insecticides indicated that Azodrin and Bidrin were about equally toxic and much more so than CL-47031 and Temik, and that of adults caged on individual plants in flower that had been treated with Azodrin or CL-47031 suggested that the moths may be killed by the systemic action of these insecticides translocated to the nectar. When adults of H. virescens were released on plants each treated with Azodrin at 25 or 30 mg. in large field cages, reductions in the numbers of eggs deposited, attributed to the effect on the moths of the insecticide in the nectar, and in the numbers of developing larvae, were substantial. Azodrin was the most consistently effective of the four insecticides evaluated.
