白僵菌制剂不同剂型防治玉米螟的研究 总被引:1,自引:0,他引:1
1989年在辽宁省昌图县进行白僵菌制剂不同剂型防治亚洲玉米螟试验。大区试验结果表明:在亩施菌量相等条件下,用可湿性粉剂喷雾,粉剂喷粉和手撒颗粒剂防治效果差异不显著。用2.5×10~4亿孢子/亩剂量,在玉米心叶期防治一次,玉米螟幼虫可减少90.5~91.6%。用同上剂量和剂型,在两个乡镇1.2万亩玉米上大面积防治示范,三种施药方法玉米螟话虫数分别减少86.9%、80.7%和78.5%。其中可湿性粉剂喷雾防治效果和防治工效均较高,防治费用较低,无粉尘污染,菌剂便于运输及贮存,且适合于超低量喷雾,有推广和发展前景。 相似文献

We evaluated, water-based very-low volume (VLV) sprays of various pyrethroids at different dosage levels, comparing these with ultra-low volume (ULV) sprays for the control of cotton pests in the Nampula province of Mozambique. The results showed that karate (lambda-cyhalothrin) 2.5% SG at a dosage level of 15 g a.i./ha applied as VLV gave a significantly higher yield than karate 0.8% ULV (28 g a.i./ha). Also, karate 3.75% WG (12 and 15 g a.i./ha) gave a similar yield to that of karate 0.8% ULV (28 g a.i./ha). Karate 5% EC (15 and 20 g a.i./ha) gave a yield similar to Karate 0.8% ULV (28 g a.i./ha). Baythroid (cyfluthrin) 5% EC at 15, 22.5 and 30 g a.i./ha gave a yield similar to baythroid 1.2% ULV (36 g a.i./ha). Bulldock (beta-cyfluthrin) 12.5% SC at dosage levels of 6, 9 and 12 g a.i./ha gave a similar yield to that using baythroid 1.2% ULV (36 g a.i./ha). In all four trials, water-based VLV sprays gave a yield of cotton and degree of pest-control similar to those obtained with the ULV formulations at comparatively lower dosage levels. Integrated with other pest management practices, these could play an important role in the cost effective management of insect pests of cotton on small-scale farms in many countries. 相似文献

In 3 year field experiments on the development of more economical methods for pest and disease control on intensively planted dessert apple trees, low dose applications of one-tenth of the normal quantities of pesticide in one-hundredth, one-tenth and one-fifth of the normal volumes were compared with conventional high volume spraying at 2250 litres/ha. An experimental tractor-mounted mist blower, a motorised knapsack mist blower and a fan-assisted disc sprayer were each used to apply the pesticides in 225, 45 and 22.5 litres of water/ha. Control of the apple-grass aphid, Rhopalosiphum insertum, obtained by low dose spraying of demeton-S-methyl (8 g a.i./ha) combined with azinphos-methyl (37 g a.i./ha) in 225 and 22.5 litres/ha in 1971 and of fenitrothion (70 g a.i./ha) in 225, 45 and 22.5 litres/ha in 1972 and 1973 was almost equal to that obtained by the conventional high volume method. Low dose applications of benomyl fungicide programmes gave poor control of apple scab, Venturia inaequalis in 1971 when the disease incidence on the fruit was very high at 73%, but in 1972 and 1973, when it was moderately high at 42–45%, control was almost equal to that given by the conventional high volume method. Under these conditions all the low dose methods gave better control with benomyl than with dodine/captan programmes. 相似文献

Bait spraying at a rate of 1 lit./ha. (0,2 lit. of ULV Malathion at 96%+ 0,8 lit. protein hydrolysate Atropaz) gave positive results in the control of the olive fly and olive moth but was insufficient against the olive weevil. Applications at low and ultra-low volume were clearly more economical and permitted larger areas to be treated. Therefore, it is suggested that the use of malathion concentrate aerial bait spraying be expanded in Cyprus in the control of olive fly. 相似文献

In Italy, conventional spraying techniques are still commonly used in the South, the Centre as well as in several northern regions. Applications at semi-low volume (1,800–2,000 1./ha.) mainly on fruit trees and tobacco represent 10 to 20% of the total. Ground equipment is seldom used with low and ultra-low applications whereas the surface covered by aerial treatments is rapidly increasing reaching now 70,000 ha. per annum. 相似文献

Abstract Helicopter applied insecticides used for tsetse control were investigated for their potential to reduce populations of Simulium damnosum s.l. in riverine forest in the Guinea savanna zone of southwestern Upper Volta. Populations of aquatic stages and biting females were sampled before and after spraying. Deltamethrin applied at 12·5 g a.i./ha to a 30 km length of riverine vegetation almost eliminated adults for a period of about nine days. Residues which fell into the water killed all larvae in the river. Endosulfan at 100 g a.i./ha applied to a similar stretch of vegetation caused a reduction of over 60% in biting adults for 11 days, but residues falling into the river killed only young larvae. Neither dieldrin at 400 g a.i./ha, endosulfan at 10 g a.i./ha nor deltamethrin at 12.5 g a.i./ha applied to a 5 km insecticide barrier between the experimental blocks and the untreated river appeared to have much effect. This suggests that most S. damnosum were traversing the barrier without coming into contact with the insecticides. 相似文献

Abstract V.I.v. captafol spray treatments applied using a 1.8m swath (3.3 kg a.i./ha/application) were more effective than treatments using a 3.6 m swath (1.67 kg a.i./ha/application). At sites with more than 700 mm rainfall during the crop's field life weekly applications were more effective than spraying at 10- and 14-day intervals, but at the drier sites (< 650 mm rainfall) spraying at 10 days was adequate. 相似文献

Abstract Field experiments were conducted during two dry seasons in northern Nigeria to identify suitable pre‐transplant herbicides for weed control in irrigated tomatoes. At Samaru in the northern Guinea savanna, diphenamid at 1.5 kg a.i./ha followed by supplementary hoe‐weeding, metribuzin at 0.5 kg a.i./ha, diphenamid at 3.0 kg a.i./ha, metolachlor plus metobromuron at 1.0 + 1.0 kg a.i./ha and two or three hoe‐weedings, resulted in higher tomato yields than the untreated controls, and most of these treatments reduced weed infestations significantly in both years. At Bakura, in the Sudan savanna zone, metribuzin at 0.25 and 0.5 kg a.i./ha, diphenamid at 3.0 g a.i./ha and chloramben at 1.5 kg a.i./ha plus supplementary weeding consistently resulted in yields that were similar to two hoe‐weedings and higher than the untreated controls. Three kg a.i./ha of chloramben depressed yields in all the trials. At both sites hoe‐weeding once six weeks after transplanting gave unacceptably low crop yields, but similar high yields were obtained with two or three hoe‐weedings. Supplementary hoe‐weedings were unnecessary with the application of metribuzin at 0.5 kg and metolachlor plus metobromuron at 1.0 + 1.0 kg a.i./ha. Uncontrolled weed growth resulted in a 53–67% reduction in tomato fruit yield. 相似文献

表面活性剂、喷液量及杂草叶角对普杀特喷后附着量的影响 总被引:7,自引:1,他引:7
表面活性剂、喷液量及杂草叶角对普杀特在非敏感杂草马唐叶片上的喷后附着量有明显的独立影响和交互影响,其中表面活性剂的影响最大。供试的6种非离子型表面活性剂均因显著降低了普杀特药液的表面张力从而显著提高了其在马唐叶片上的喷后附着量,其中ScOil和Silwet—L77对其提高幅度最大;普杀特在马唐叶片上的喷后附着量随着喷液量的减少逐步增加,但在0—90°范围内随着马唐叶角的减小而减少,其由于喷液量的增大或马唐叶角的减小而引起的下降量,可通过加入非离子型表面活性剂而得到补偿,加入非离子型表面活性剂配合下午微液量(90L/ha)喷施,可望最大限度地增加普杀特在其非敏感杂草叶片上的喷后附着量,进而提高其药效,降低其使用成本和减少其在土壤中的残留。 相似文献
