Abstract
The present invention relates to asomate which is an arsenical pesticide with improved drug toxicity, and the arsenical pesticide comprises 6 to 12% of asomate or 15 to 30% of asomate wettable powder, 25 to 50% of humic acid or soduim salt and 5 to 20% of auxiliary agent. Since the asomate is on the carrier of the humic acid or the soduim salt, bactericidal power is reinforced, drug effect is lasting, the capability of the arsenical pesticide on curing injury is superior to that of other pesticides, and simultaneously, the present invention has the advantages of favorable adhesive force, high permeation performance, low toxicity, easy storage and easy use.
Description
The present invention relates to contain the bactericide of arsenic element, it is a kind of conditioning agent of preventing and treating apple valsa canker and promoting plant growing.
Prevent and treat apple valsa canker at present and generally all be organoarsenic fungicide three-N-dimethyl dithiocarbamic acid arsenic of using nineteen fifty-nine Japan " イ Ha ラ agricultural chemicals company " exploitation and be its structural formula of asomate for (
s(according to＜Japanese pesticide developing organon〉introduce).People made improvements again afterwards, add compound and make it become wetting powder in asomate, and adding peregal again becomes the flat liquid of arsenic again.Although above-mentioned two kinds of agricultural chemicals sterilizing powers are good, the toxicity plant tissue to the tree body greatly is harmful.
In view of above-mentioned the deficiencies in the prior art, the invention provides the antibiotic and strong agricultural chemicals of callus ability of a kind of high-efficiency low-toxicity.
Purpose of the present invention can reach by following measure: Asomate, slow-releasing arsenical pesticide is the improved arsenic agricultural chemicals that contains of a kind of drug toxicity, but it is characterized in that containing 6～12% asomate or 15～30% asomate wet-millings (asomate content is 40%), 5～20% auxiliary agent, 25～50% humic acid or sodium salt.But preferred plan is to contain 8% asomate or 20% asomate wet-milling (asomate content is 40%), 15% auxiliary agent, 40% humic acid or sodium salt.Institute's auxiliary agent in addition is bleeding agent and binding agent.
Asomate, slow-releasing arsenical pesticide is to be raw material with the asomate, and the organic high molecular compound humic acid is made carrier (stabilizing agent), adds other multiple additive mixture in addition again and makes.
The humic acid molecule is by some similar formed macrocomplexs of aromatic series construction unit, and each unit is made up of nuclear, bridge, key, active group, and the simplest humic acid construction unit can be schematically as follows:
The macrocomplex that the countless architectures unit forms has constituted the existence of a large amount of active groups, thereby has determined special natures such as humic-acid kind possess hydrophilic property, ion exchangeable, complexing and adsorption capacity and physiologically active.It and asomate react in the aqueous solution, and asomate is attracted on humic acid or the humic acid sodium salt, and former medicine is changed by changing low toxicity into than high toxicity, have improved drug effect owing to the slow releasing function that adsorbs and complexing rose then.Humic-acid kind promotes plant to inorganic absorption of healing the wounds and conveying characteristic by the complexing of itself and the permeability of change plant biological film in addition, has increased callus ability and the antibacterial ability of fruit tree.(relevant humic acid has facilitation to plant growing and is generally acknowledged already)
The concise and to the point technological process signal of its preparation of agricultural chemicals of the present invention as
The concrete practice of the present invention is: but with 6～12% preferably 8% asomate or 15～30% preferably 20% asomate wet-milling (containing asomate 40%) with 25～50% preferably 40% humic acid or sodium salt react in water, its reaction time is 2～10 hours, preferably 5～6 hours; Temperature is 50～100 ℃, preferably 70～100 ℃; Add auxiliary agents such as bleeding agent, binding agent then, as penetrant t, synthetic resin, draw back powder B
XDeng, its consumption is 5～20% preferably 15%, gets product through post processing again.
Pesticide sterilizing power of the present invention is strong, lasting medicine, callus ability are better than other agricultural chemicals, and adhesion strength is good, penetration is strong, and low toxicity easily stores, easy to use.
Embodiment 1
With 58 kilograms of pH values is that 9 content are that 50% sodium humate adds and has in the reactor of agitator, adds water and is warming up to 70 ℃ for 3 times, when treating that sodium humate dissolves fully, but adds 30 kilogram of 40% asomate wet-milling.React and add auxiliary agent penetrant t, synthetic resin after 5 hours, it respectively is 5 kilograms.Mix and delivered to the comminutor granulation in 1 hour, then its oven dry is made it moisture less than 5%, get 102 kilograms of finished products of Asomate, slow-releasing arsenical pesticide.
