Description

A kind of medicinal plant insecticide

Technical field

The present invention relates to a kind of medicinal plant insecticide that is used for crops

Background technology

At present, the insecticide that is used for crops all is a chemical pesticide, and chemical pesticide has played huge effect on control damage by disease and insect, raising crop yield.But meanwhile, the residual environmental pollution that causes of chemical pesticide is also serious day by day, and chemical pesticide enters in people's carcass by food chain and produces significant damage.And the chemical pesticide structure is single, and the residence time is long, and the pesticide resistance of insect is easy to form.There are some researches show: the disease of cancer, serious harm human health such as cardiovascular and the excessive use of chemical pesticide are closely related.Along with increasing the weight of of environmental pollution, people more and more pay attention to the research work of vegetable insecticide.

In order effectively to solve the pollution problem of chemical pesticide, the present invention has selected several plants that have control and kill the damage by disease and insect effect on the basis of Chinese patent ZL021284504, developed a kind of noresidue, the non-harmful medicinal plant insecticide that is used for crops.

Summary of the invention

The object of the invention is that the medicinal plant insecticide that is used for crops of development, this insecticide are to be made by the achene of Siberian cocklebur, Chinese catalpa fruit, Achnatherum inebrians, sweet basil, Ferula sinkiangensis, malicious Li, inflammation fiber crops, herba sophorae alopecuroide, radix aconiti agrestis, henbane seed; Show through a large amount of field test results to cotton, wheat, corn, gourd, fruit and vegetable: this insecticide makes the increasing crop yield good harvest to the efficient 90%-95% of reaching of diseases and pests of agronomic crop such as cotten aphid, two spotted spider mite, Amrasca biguttula (Ishida), cabbage caterpillar.

A kind of medicinal plant insecticide of the present invention, this insecticide is by raw material achene of Siberian cocklebur 1-9 part, Chinese catalpa fruit 1-9 part, Achnatherum inebrians 1-9 part, sweet basil 1-9 part, Ferula sinkiangensis 1-9 part, malicious lamb's-quarters 1-9 Fen, inflammation fiber crops 1-9 part, herba sophorae alopecuroide 1-9 part, radix aconiti agrestis 1-9 part, henbane seed 1-9 part, adopt and extract pharmacological component, pulverize, sieve, add water, heating and refluxing extraction, the concentrating under reduced pressure step is made.

A kind of medicinal plant method for producing insecticide follows these steps to carry out:

A, take by weighing the achene of Siberian cocklebur, Chinese catalpa fruit, sweet basil, Ferula sinkiangensis root respectively in proportion and pulverized the 80-120 mesh sieve, add the water that 10-20 doubly measures, heating, temperature is 80 ℃ of-95 ℃ of refluxing extraction three times, each 2-6 hour, filter, merge No. three times extract, be evaporated to that to contain the crude drug amount in every milliliter of extract be 0.5-2 gram, standby;

B, take by weighing malicious Li, inflammation fiber crops, herba sophorae alopecuroide, radix aconiti agrestis, henbane seed respectively in proportion and pulverized the 80-120 mesh sieve, add the water that 10-20 doubly measures, heating, temperature is 80 ℃ of-95 ℃ of refluxing extraction three times, each 2-6 hour, filter, merge No. three times extract, be evaporated to that to contain the crude drug amount in every milliliter of extract be 0.5-2 gram, standby;

C, the extract after a and b concentrated mix, and stirring to obtain vegetable insecticide.

A kind of medicinal plant insecticide of the present invention in use, is mixed with the emulsion of 0.5%-1% with the finished product water after concentrating, and sprays the effect that can play desinsection on the blade face of crops, and general crops are used 2-3 insecticidal effect the best.

A kind of medicinal plant insecticide of the present invention, the various plant performances of forming this insecticide are:

The achene of Siberian cocklebur (Xanthium strumarium L.) is a composite family annual herb plant, mainly be grown near the farmland, Plain and road by.All there are distribution, aboundresources in the various places, Xinjiang.Its main component is strumaroside, xanthanol, xanthumin, vitamin C and alkaloid etc.Crops are had promotion growth preferably and kill the damage by disease and insect effect.
