Two sprays were given in November, 1977 and January, 1978 synchronising with the emergence of new flushes and inflorescences. The infestation of shoots and inflorescences was significantly reduced in the plots which received aerial spraying and the yield increase was 40 per cent for the number of nuts and 37 per cent for the weight of nuts harvested over the plots receiving high voulme spray (2.2 kg Vs 1.6 kg per tree).encashew pesttea mosquitoaerial sprayingArticle
