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.
The appropriate time of applying LS-1 mixed with adjuvants was between 7d before fungus invading tomato and 7d after fungus invading tomato, control effect in this period was from 54.09% to 86.90%,and the time internal was 5d~7d.
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 the relative control efficacy against bamboo aphids on selected shoots with three dilutions was 60.0%, 75.1%, and 80.7% within 7 days after spray, respectively. With the increase of the conidia concentration, the control efficacy was enhanced.
The results showed that the disease development were delayed 9d and 7d respectively after treated with ATm044 and Asp061 in greenhouse. The incidence of disease were 43.3%-61. 7% and 46. 6%-67. 8% respectively, the control effects were 56. 7% and 53.4% in greenhouse.
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%.
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%.
The experiment showed that coating cucumber (cv.Nongcheng No.4) seeds with “Cucumber Seedcoat Agent No. 1” could improve seed germination and storage ability,promote emergence,favor the stronger seedling raising,and significantly increase seedling cold tolerance. The prevention effect on seedling fusarium wilt was 90.5%,and on seedling comprehensive diseases was 77.8%.
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.
