(Pdf) the repellent effect of some indigenous plant extracts against pulse beetle (callosobruchus chinensis) gas in oil


The sgas belfast powdered leaves of Cassia sophera along with hot- and cold-water leaf extracts of this plant were tested in laboratory experiments in the UK and in field trials in Tamale, Northern Ghana, using traditional storage containers, to determine their inhibitory and electricity and circuits toxic effects against Sitophilus oryzae and Callosobruchus maculatus infestation of stored rice and cowpea, respectively. Laboratory and field experiments with cowpea showed that the use of C. sophera hot-water extracts was more effective at reducing C. maculatus infestation and adult emergence on cowpea than the traditional leaf-powder application (1% and 5% w/w) or the use of a cold-water extract of C. sophera. Hot-water extracts of C. sophera electricity generation might be a more effective technique of applying the plant material on to stored cowpea than using powdered C. sophera leaves, the currently used application by small-scale farmers. In contrast, experiments with S. oryzae on rice electricity water analogy showed that C. sophera leaf powder (5% w/w) effectively reduced adult emergence in the laboratory, but this could not be confirmed under field conditions. The hot and dry climatic conditions in the field might impart a natural protection against rice infestation by S. oryzae, making the gas key bolt carrier use of protectants and pesticides less necessary for farmers. This was supported by the negligible rice grain damage after 6 months of field gas hydrates wiki storage and by the failure of the S. oryzae population to establish itself under field conditions. The implications of using botanicals in pest control are discussed.

This study was conducted to investigate a cheap and readily electricity tower vector available alternative control measure for cassava anthracnose disease causal agent ( Colletotrichum gloeosporioides f. sp. manihotis ), through the use of antimicrobial crude plant extracts such as neem ( Azadirachta indica ), bitter leaf ( Vernonia amygdalina ), Ocimum gratissimum and Xylopia aethiopica, on the fungal growth parameters (mycelial growth, sporulation gas mask tattoo and germtube development). The extracts at concentration levels of 25, 50, 75 and 100% full strength concentration showed an inhibitory effect on mycelial growth, germ tube development and sporulation of fungal isolates 05FCN, 10FCN, 12FCN and 26FCN. Neem seed and leaf extracts at 100% showed a total reduction in sporulation in most of the fungal electricity and magnetism ppt isolates. The inhibitory properties of the plant crude extracts indicated a promising control option for consideration in cassava treatments of planting stocks, particularly in areas where farming is at a basic subsistent r gas constant kj level, and less available money to meet the high cost of pesticides.

Experiments were conducted to study the bioefficacies of different plant/weed derivatives that affect the development of the pulse beetle, Callosobruchus maculates F. (Coleoptera: Bruchidae) fed on black gram, Vigna mp electricity bill payment online indore mungo, seeds. Plant extracts, powder, ash and oil from nishinda (Vitex negundo L.), eucalyptus (Eucalyptus globules Labill.), bankalmi (Ipomoea sepiaria K.), neem (Azadirachta indica L.), safflower (Carthamus tinctorius L.), sesame gas exchange in the lungs occurs in the (Sesamum indicum L.) and bablah (Acacia arabica L.) were evaluated for their oviposition inhibition, surface protectant, residual toxicity and direct toxicity b games unblocked effects on C. maculates. The results showed that plant oils were effective in checking insect infestation. The least number of F(1) adults emerged from black gram seeds treated with neem oil. The nishinda oil extract was the gas company most toxic of three extracts tested (nishinda, eucalyptus and bankalmi). Bablah ash was the most effective compared to the powdered leaves of nishinda, eucalyptus and bankalmi. The powdered leaves and extracts of nishinda, eucalyptus and bankalmi, at a 3% mixture, provided good protection for black gram seeds by reducing insect oviposition, F(1) adult emergence, and grain infestation rates. The oil treatment did not show adverse effects on germination capability gas pain of seeds, even after three months of treatment.
