Grain damage

Suffusion, one of the primary types of internal erosion, preferentially erodes fine grains inside the skeleton of coarse particles due to interstitial permeability. The occurrence of suffusion damages earthen dams and affects the living environment around these structures.

Sitophilus zeamais Motschulsky, 1855 (Coleoptera: Curculionidae) which develops inside the grain, is an aggressive pest of stored grains. Here, we evaluated the efficiency of diatomaceous earth (DE), Diatomita CI/325 CX, and dolomite (DOL), Dolomita Dr. Kanyo, against S. zeamais reared on corn under laboratory conditions and observed external alterations on treated insects using scanning electron microscopy (SEM). Insects treated with both DE and DOL were impregnated with particles on the body surface, and they showed 100% mortality after 10 days of exposure.

Efficient post-harvest handling storage can tremendously contribute to socio-economic empowerment in developing nations. Farmers use traditional storage containers for storing food grains for their own need. These storage structures are comparatively cheap, eco-friendly and impart high shelf life to the stored commodities. These traditional storage systems could be applied in modern storage areas with minor modification, could save food commodities that would be damaged by insects.

The presence of heavy metals in environmental waters having an important place in the industrial waste is a major threat to viability. Heavy metals are transported to humans through the ecological cycle, damaging many tissues and organs. In recent years, agricultural and food waste can be used to remove heavy metals. At the present study, magnetically modified coffee grains which are alternative to conventional particle systems were prepared and heavy metal removal performances were investigated. The coffee grains used were magnetically modified by contact with water-based magnetic fluid.

This study was aimed at quantifying yield loss due to high temperature induced damages on head rice recovery in rice. Fifteen rice varieties were evaluated over 3 seasons and their head rice recovery was estimated. Results of this study revealed that day temperature had no influence on the head rice recovery whereas night temperature had negative impact on head rice recovery at p < 0.05.

Laboratory experiments were carried out to study the effect of milling methods on the infestation of Sitophilus oryzae on stored rice grains during 2016-17. The results of the present investigation reveals that rubber milled rice were more preferred by the weevils than the iron milled rice with significant differences in weight loss existing among the various rice categories and the highest weight loss per cent was registered from SBA rice category (31.26±0.60 and 33.07±0.62) and the lowest from SMNA rice category (24.47±0.55 and 25.98±0.56) in 2016 and 2017 respectively.

Rice crop accounts for nearly a third of the total area under food grains in India and is the staple food for a significant portion of the world‟s population. Widely varying factors influence the growth of rice in different rice growing areas and render the crop susceptible to various pathogenic and non-pathogenic diseases, resulting in extensive damage of grain and straw yield. Bacterial leaf blight disease of rice caused by Xanthomonas oryzae pv. oryzae (Xoo) is a serious menace to rice production in India, besides other rice producing countries.

Twenty nine long duration pigeonpea genotypes were screened for their reaction against pod fly during Kharif 2014-15 at the Agricultural Research Farm, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi. The first incidence of pod fly was observed in the 4th standard week in all genotypes except IVT-509, AVT-607 and AVT-605 and the population persisted up to 12th standard week in all the genotypes.

Insects cause great damage to agricultural crops. A secondary effects of pest is viral, bacterial and fungal infection where are facilitated by the damages and injured to crop plants by insects and mites. The yield loss of crops by nibbling, injury and growth retardation is estimated to be 20% - 30%. An additional 10% is lost during post harvest storage and transportation. Decrease in crop quality causes further economic loss.

The methanol extract from leaves of Saraca indica was investigated to control insect infestation of stored food commodities viz. maize, rice, cowpea and wheat flour during from Ostrinia nubilalis, Spodoptera littoralis, Callosobruchus maculates and Tribolium confusum. After introducing the test insects, stored food samples were fumigated with methanol extract from leaves of Saraca indica at 500 μg/mL (ppm). The methanol extract significantly enhanced feeding deterrence in insects and reduced the grain damage as well as weight loss in fumigated food samples infested with all insects.
