Abstract

An agricultural chemical in the form of liquid for preventing and eliminating red spider, aphide, cabbage worm, sawfly, tent caterpillar, pine moth, etc. with higher effect is prepared from oil-tea camellia dregs, tobacco stem, pink plumepoppy herb, honeylocust thorn and stemona root through extraction and mixing.

Description

A kind of agrichemical without enviromental pollution for plant--three bitter principles

The present invention relates to a kind of agrichemical without enviromental pollution for plant,, low toxicity efficient because of it, noresidue, to person poultry safety's characteristic are applicable to agriculture and forestry plant, are particularly useful for fruit tree, tealeaves, vegetables, greenhouse and flower garden aquaculture.Two spotted spider mite, aphid and various lepidoptera pest all there is good preventive effect.

As everyone knows, chemical pesticide pollutes the environment harm humans health in production and use.According to world WHO tissue statistics, there are every year 750000 people that pesticide poisoning takes place, wherein 1.8 ten thousand die.The chronic poisoning person's who causes as for pesticide pollution environment, grain, vegetables and food etc. quantity is just bigger, harm also just more very.Problem is still more and more serious though the regulation that country has carried out forbidding and limited the use of many chemical pesticides, the agricultural chemicals of pesticide poisoning, vegetables and fruit exceed standard.Beijing is example, and in the vegetable and fruit selective examination of a market of farm produce sale at the bottom of nineteen ninety-five, the super malicious sample rate of different cultivars reaches more than the 15-32%.

Therefore the development of public nuisance-free agricultural chemicals is just arisen at the historic moment, and all is utilized such as Dalmatian chrysanthemum, trifoliate jewelvine, kuh-seng, thunder godvine and the root of langdu, but because these plant resourceses are limited, often can not be formed with the lasting industry of certain scale.

Task of the present invention provides a kind of unique agrichemical without enviromental pollution for plant of filling a prescription, and its primary raw material mostly is residue after the agriculture and forestry product processing (withered as tea, tobacco stem etc.), turns waste into wealth, and resource also can be exhausted.

Task of the present invention is finished as follows: according to the combination principle of traditional Chinese herbal medicine, in conjunction with the requirement of modern agriculture chemical compounding technology, form through scientific composition, constant temperature extraction, processing chelating.The main chemical of botanical pesticide of the present invention--three bitter principles--has theophylline (Theophyllin), nicotine (Nicotine), stemonine (Stemonine), bocconine (Bocconine) and saponin (Saponine) etc., and is aided with other auxiliary agents.

Now be described further as follows for example: primary raw material has that tea is withered, tobacco stem, macleaya cordata, Chinese honey locust and the tuber of stemona.Preceding two kinds is residue after the agriculture and forestry product processing, and tea is withered to be oil cake after the southern tea seed oil expression, and tobacco stem is the offcuts of suncured tabacco or cigarette industry; Macleaya cordata is that mountain forest plant, Chinese honey locust and the tuber of stemona are traditional Chinese medicine, and the function of decontamination desinsection is arranged.

--constant temperature boiling--high pressure diacolation--refining--composite--encapsulation that the technological process of producing is that above-mentioned raw materials is soaked respectively.Wherein withered, the nicotine of tea, macleaya cordata, Chinese honey locust and the shared percentage (W/W) of the tuber of stemona are respectively 35-40%, 20-25%, 6-8%, 5-7%, 5-7%.Except above-mentioned composition, also be equipped with cosolvent, bleeding agent, stabilizing agent and emulsifier etc., its content separately is about 4-10%, and total content is 25-30%.In process for preparation, should be sequentially added into the extract that has concentrated and made with extra care, behind stirring and evenly mixing, add stabilizing agent, produce white layer, and then slowly add emulsifier and disappear until white layer, meet the requirement of this prescription this moment just, reaches the miscible state of dynamic equilibrium on the physico chemistry.

This finished product is a brown liquid, through high temperature (54 degree Celsius) and low temperature (0 degree Celsius) storage test, and stable performance, no crystallization and lamination produce.

Claims

1, a kind of is that primary raw material is through extraction and the composite agrichemical without enviromental pollution for plant that forms--three bitter principles with tea withered (1), tobacco stem (2), macleaya cordata (3), Chinese honey locust (4) and the tuber of stemona (5), it is characterized in that the ratio of above-mentioned composition (W/W) is respectively 35-40%, 20-25%, 6-8%, 5-7%, 5-7%.

2, by right 1, also be equipped with other auxiliary agents in this agricultural chemicals, as cosolvent, bleeding agent, stabilizing agent and emulsifier etc., its dish content (V/V) separately is respectively 4-10%, and total amount is 25-30%.

3, the product that regulation was mixed with according to right 1 and right 2 is a brown liquid, and physical and chemical performance is stable, and no crystallization and lamination take place.
