“…Since carbaryl at 0.02 per cent caused about the same degree of thinning as at 0.08 per cent it appears there is no necessity to use concentrations higher than 0.02 to 0.04 per cent for commercial thinning of Granny Smith in southern Victoria. This confirms the results of Batjer and Thomson 1961 ;Cripps and Halse 1962 ;Stebins 1962 ;Southwick, Weeks and Olanyk 1964 ;Teskey and Kung 1967, who found that carbaryl does not have any significant ability to increase the rate of thinning at higher concentrations. The fungicide thiram also caused significant thinning of Granny Smith apples similar to that obtained by carbaryl.…”

“…Since then, this material has been widely tested and numerous authors (Batjer and Thomson 1961 ;Cripps and Halse 1962 ;Stebins 1962 ;Batjer and Billingsley I 964 ;Southwick, Weeks and Olanyk 1964 ;Teskey and Kung 1967 ;andVeinbrants 1961 and1963) found that carbaryl is a very effective and consistent thinning agent for certain apple varieties. In addition, thinning with this material does not increase with concentration (Batjer and Thomson 1961 ;Cripps and Halse 1962 ;Teskey and Kung 1967).…”

Evidence is presented that a single application of the fungicide thiram at 0.12 per cent, applied 14 and 21 days after full bloom on Granny Smith apples, reduced the fruit set highly significantly, and to about the same extent as carbaryl at 0.02, 0.04, or 0.08 per cent applied 14 days after full bloom. Either material resulted in good fruit thinning. Carbaryl caused about the same degree of thinning over a wide range of concentrations, the only significant difference being between 0.02 and 0.16 per cent (P<0.05). Applications of N.A.D. at 25 p.p.m., and N.A.A. at 5 p.p.m. caused more drastic reduction in fruit set than carbaryl at 0.02, 0.04, and 0.08 per cent, or thiram at 0.12 per cent, applied at the same time. Carbaryl resulted in the most uniform fruit thinning, followed by thiram, N.A.D., and N.A.A. All spray treatments improved fruit size, reduced fluctuations in cropping, and significantly increased fruit yields over a period of four years as compared with unsprayed, hand thinned trees.

“…The reduction in titratable acidity content in carbaryl treated samples was not significant, as in other cases. Teskey and Kung [32] reported that the carbaryl application in apple cultivation also did not influence the level of acids in apples. The crude protein content of azadirachtin, cypermethrin and carbaryl treated fruit samples was found to be nonsignificant in comparison to the control.…”

Abstract. Brinjal (Solanum melongena L.) suffers from the attack of various pests throughout its different stages of the crop growth. Different insecticides are used to control these pest infestations. The application of these insecticides on brinjal plants may have an effect on their quality and nutritional parameters of fruit samples. In the present study effect of three different insecticides viz. Triazophos 40% E.C. Carbaryl 50% W.D.P, Cypermethrin 10% E.C. and Azadiractin 10,000 ppm formulation belonging to different groups namely organophosphate, carbamate, synthetic pyrethroids and botanical insecticide on brinjal fruit quality, nutritional parameters and total antioxidant capacity (TAC) were assessed in field conditions. The results showed that different insecticides at field application dose showed minute insignificant variation in fruit nutritional and total antioxidant activity parameters in comparison to the control samples. The fruit quality parameters also showed minute variation in comparison to the control, except in the case of Triazophos treated samples which showed significant variation (p<0.05) in total soluble sugar content and crude protein.

Some Effects of Carbaryl on Two Apple Cultivars

Abstract: No elTect v'as noted on quality and kceping properties of the fruit, nol did carbaryl influence reducing-sugar and acid le'r.els, and acid-sugar ratio. Bean stem curvature tests indicated that the chemical interfered u'ith the transport system of the treated apple trees.
