[Method] The calcula- tion procedure of using Visual Basic to conduct statistical analysis on the field efficacy of pesticides was introduced, and an example was used to illustrate the usage and skill of the program. [Result] The procedure could quickly and accurately con- duct statistical analysis on the field efficacy of pesticide by only inputting initial data of the test, and it could compare the significance of differences between various fac- tors. Its calculated results were consistent with the results of the specialized statisti- cal software DPS. [Conclusion] It is a quick and simple method with high accuracy and reliability, which can greatly improve the efficiency of pesticide formulation opti- mization.展开更多

[Method] The combined method of indoor toxicity test, field efficacy test, fast testing of pesticide residues and residual toxicity determination were adopted to carry out test. [ Re- suit] Indoor toxicity results showed that LC50 of mulberry No. 1 against Hyalopterus amygdale was （316.1±57.3） mg/kg, and the control effect of mulberry No. 1 at 14 d reached 62.58% ; fast testing of pesticide residues at 7 d showed that the mulberry leaves were safe to silkworms, which reached the standard of leaves for silkworm. [ Conclusion] Mulberry No. 1 was recommended to be the Special pesticide to apply in mulberry field.展开更多

Several topical preparations are available on the veterinary market, which are licensed for an either specified duration of treatment or for a discretionary period that is determined by the clinician. Objectives: To compare the efficacy of two topical products, both licensed for the treatment of otitis externa in the dog, but with different treatment durations. Animal Population: One hundred and sixty dogs were enrolled in this multicentre field study from which 157 dogs were analysed in the Per Protocol sample (73 Aurizon?treated animals and 84 Easotic?treated animals). Method: Dogs were randomly assigned to Aurizon?or Easotic?treatment groups. Aurizon?(Vétoquinol SA: marbofloxacin, clotrimazole, dexamethasone) was administered daily in the affected ear(s) for 7 or 14 days, and was compared with a daily administration of Easotic?(Virbac SAS: gentamicin, miconazole, hydrocortisone aceponate) for 5 days. General and localised clinical signs were scored on days 0 (D0), 3 (D3), 7 (D7), 14 (D14) and 21 (D21). Results: Clinical cure rates at the end of treatment were 56.3% and 48.8% (p=0.35) in the Aurizon?and Easotic?groups respectively and 81.2% versus 74.7% one week after completing the course of treatment (p = 0.34). Twenty-one days after initially presenting for the study, cure rates were 84.3% in the Aurizon?group and 73.8% in the Easotic?(p=0.12). A relationship between severity of clinical signs and treatment duration was observed. Conclusion and Clinical Significance: At the end of the trial period, cure rates showed a tendency to be higher in the Aurizon?treated animals. The flexible dosage and the veterinary monitoring permitted treatment duration to be adjusted based upon the severity of otitis externa thus increasing the likelihood of clinical cure.展开更多
