Field Application of Bio-Insecticides On Spiny Bollworm, Earias insulana (Bosid.) On Cotton by Using Recent Low Volume Ground Spraying Equipment

“…and Hand-held Hydraulic sprayer (Matabi) (56 L./Fed.) that decreased infestation of spiny bollworm E. insulana on cotton crop, these results agreed with Hindy et al (2004) and Genidy et al (2005) which recommended KZ oil and Pyriproxyfen followed by Agerin using low volume spraying because of reducing the time lost in process filling the machines, improve the homogeneity of the spray solution on the plant leaves and saving the lost spray of the ground and Bakr et al(2014). The data showed that Economy Micron ULVA sprayer (15 L./fed.)…”

EVALUATION OF TWO GROUND SPRAYING EQUIPMENTS FOR CONTROLLING SPINY BOLLWORM Earias insulana (BOISD.) IN COTTON FIELD

“…and Economy Micron ULVA sprayer (15 L./fed. ), these results agreed with Hindy et al, (2004) and Genidy et al, (2005) which recommended KZ oil and Pyriproxyfen followed by Agerin using low volume spraying because of reducing the time lost in process filling the machines, improve the homogeneity of the spray solution on the plant leaves and saving the lost spray of the ground and Bakr et al,(2014). The data showed that Economy Micron ULVA sprayer (15 L./fed.)…”

RESIDUAL ACTIVITY STUDY OF CERTAIN GROUND SPRAYING EQUIPMENT FOR CONTROLLING BEAN APHIDS WITH PRIMICARB INSECTICIDE ON Vicia fabae (L.) PLANTS IN EGYPT

“…Primicarb with total recommended dose revealed the best bioefficiacy results with the three tested sprayers,also best bioefficiacy obtained results with Solo sprayer (22 L/fed.) for both doses, and these results agreed with Hindy et al (2004) , Genidy et al (2005) which recommended KZ oil and Pyriproxyfen followed by Agerin using low volume spraying because of reducing the time lost in process filling the machines, improve the homogeneity of the spray solution on the plant leaves and saving the lost spray on the ground,these results also in agreement with Bakr et al (2014) they recommended by using Profenofos followed by Pyriproxyfen and Spinosad with Agromondo sprayer(20L/fed.).…”

“…In order to evaluate the tested compounds on them, pre-treatment count was recorded before spraying at five marked plants for each treatment, and post-treatment count was recorded after 3 days from treatment to determine the effect of the tested chemicals. According to Bakr et al (2014), the 2 nd spray takes place after 15days from the 1 st spray.…”
