Mitaijunjing 6% AS diluted at 75 mg/L provided 83.85% relative control effect, which was significantly better than that of Triadimefon 15% WP at 300 mg/L in the field experiments. Mitaijunjing is safe to cucumber leaves and fruits in all experiments.
Field experiments in Guiyang and Ningxiang counties of Hunan Province showed that in 2005 and 2006,the control efficacy of B-001 on R. solanacarum ranged from 40.03% to 78.14%,better than that of Streptomycini.
The results showed that Chlorothalonil 75 % WP,Thiram 50 % WP,Prochloraz 25 % EC and Mancozeb 70 % WP were good fungicides against C. cassiicola,with control efficacy 92.71 %,89.16 %,87.31 % and 73.20 %,respectively.
The results showed that benazolin & quizalofop-p-ethyl provided good control effects on weeds in rape fields,the overall effects ranged from 98.82% to 99.94% twenty days after treatment(DAT),decreased and maintained above 92% for 120 DAT with gradual decrease.
Their weed control effects were equal to that of normal herbicide with treatment at dosage of 750 g/hm2.The improved herbicide could maintain a high level of effective weed control of 89.1% and 88.0% after 30 days treatment.
The 9 common used insecticides of cypermethrin 4.5%EC,omethoate 40%EC,chlorpyrifos 40%EC,acetamiprid 3%EC,imidacloprid 10%EC provided excellent control for wheat aphids in fields. The control effects were over 90% at 7 days after spraying.
Seven kinds of germicides were tested in the control of cucumber downy milden. The result proved 52.5% of Equation WG 1 500 times,72.2% preuicur WG 800 and 64% sandofan WP 1 000 had the marked effect on control of cucumber downy mildew and,while 1 time application/six days for total of 3 times was as the treatment measure before disease occurrence,the prevention effect was above 85%.
4. Antifungal activity against plant pathogenic fungi indicated that the value of EC_(90) for HIL and FIL was 54.47mg/L and 52.89 mg/L separately; much more effective than mildiomaycin (EC90 153.22 mg/L) and triazolone (which prevention effect was 68.89% under the concentration of 100 mg/L).
Test prove: 52.5% of Equation Pro WG 1500times and 60% of Flumorph mancozeb WP 1000times have the marked effect on control of cucumber downy mildew , before disease coming on ,per 7-10d apply germicide 1 times total of 3times,the prevention effect go beyond 85%.
Flutter control effect and mechanism of central-slotting for long-span bridges
The control effect of central-slotting depends on the aerodynamic configuration of the original girder section and the corresponding central-slotting width.
The control channel is divided into two channels (fast and slow) for enhancing the speed of response at a significant range of the control effect.
Simulation results indicated that the proposed controller exhibits satisfying control effect.
The activities of enzymes responsible for lignification in pepper, pre-inoculation with arbuscular mycorrhizal (AM) fungus ofGlomus intraradices and/or infection with pathogenic strain ofPhytophthora capsici, and the biological control effect ofG.
However, the absence of pronounced control effects of most metabolites on the studied enzymes allows us to assign them to a relatively inert pool of metabolites.
Several different types of porous wall/cavity systems are tested to investigate the passive control effects.
The two logics have been tested under various driving conditions to investigate their control effects.
A model is described that allows one to compensate for the influence of perturbing factors and mutual influence of control effects on neighboring regions.
The wind-control effects of shelterbelts with different structures (close-spaced, wider-spaced, and widest-spaced) were investigated by portable wind vane and anemometer, wet and dry bulb thermometer, ground thermometer, glass service instrument.
In order to study the prevention effect of selenium in the development of cardiovascular disease, we investigated the effects of selenium supplementation on the blood rheological properties.
Calcium had a consistent prevention effect on the rate of bone loss in the 12 studies of calcium supplements in postmenopausal women.
From these results, the authors conclude that natural organic germanium has the best prevention effect for intestinal cancer in this animal model (P>amp;lt;0.01), followed by organic germanium (P>amp;lt;0.05).
However, there is no difference in the cancer prevention effect of germanium provided one month before and during dimethylhydrazine treatment, and during dimethylhydrazine treatment only.
CONCLUSIONS: Eight ppm selenium providedviadrinking water has a significant intestinal cancer prevention effect in the presence of a high dose of DMH (20 mg/kg×20 weeks), and the cancer therapeutic effect of selenium is doubtful in this animal model.
