The Effect Of Biological Activity In Two Kinds Of Anemonin With Br In Some Plant And Microbial Pathogens

Botanical pesticides,a kind of Biological Pesticides,which roots in the nature. They don't pollute environment and agriculture products usually and have low toxicity in people.They are relatively safe for people and livestock and they hurt little on natural enemies of insect pests.They can maintain the high quality of agriculture products.So they will have expansive market.And they have been widely recognized at home and broad.The paper tell the germination,growth,microbial pathogens' check experiment,chlorophyl's emperiment and cell elongation of the Anemonin with Br.The conclusion showed that:According to the experiment of the germination rate,growth,root absorption and deal with the stems and leaves.Two kinds of Anemonin with Br all represent obvious restraint effect in the experiment of growth.And in the experiment of germination rate and growth Anemonin with Br(â… ) have obvious check rate in any test.It have obvious difference with comparison in the growth experiment when the dose is 125mg/L. Anemonin with Br(â…¡) have more obvious effects in barnyard grass than in the rice in the experiment of root absorbability and rice growth.So it has choice in dealing plants.Two kinds of Anemonin with Br all represent high check rate in microbial pathogens' check experiment and conductivity experiment.Especially they have obvious check rate in Exserohilum turcicum.They don't have change in the conductivity experiment with the dose of 100mg/L.So,they can have a experiment to kill weed in the green radish area.In the experiment of chlorophyl check,Anemonin with Br(â… ) restrain all the chlorophyl content.Anemonin with Br(â…¡) restrain the content with the dose up.
