Abstract
The invention discloses a botanical pesticide for controlling rice planthopper. 45 to 55 portions of chinaberry leaves, 40 to 50 portions of Chinese wingnut leaf, and 0.8 to 1.2 portions of pericarpium zanthoxyli are taken, added with 2 to 3 times of weight of water, heated to be between 90 and 95 DEG C, decocted for 15 to 20 minutes, filtered, and deslagged; a decocted fluid is collected; and a liquid pesticide is obtained after the cooling. The botanical pesticide has good control effect on the rice planthooper, and also has certain control effect on leaf rollers at the same time; in addition; the botanical pesticide has the advantages of easily obtained raw materials, simple preparation method, and low cost; and the botanical pesticide is non-toxic, has no residue, and cannot cause the damage to people and animals.
Description
Technical field
The present invention relates to a plant material biocide, specifically, is a kind of botanical pesticide of preventing and treating rice fulgorid.
Background technology
Rice fulgorid is commonly called as the midge worm, often mixes generation with rice leafhopper in the field, is China's insect pest of rice.Rice fulgorid is caused harm to paddy rice, removes directly thorn suction juice, makes growth retardation, and the rice clump is agglomerating withered when serious, even outside the dead stalk lodging in full field, lays eggs and also can stab plant, and the destruction conducting tissue hinders the nutriment transportation and the viral disease that spreads disease.Majority is sent out field and generative center sprinkling isoprocarb, meta-tolyl-N-methylcarbamate (MTMC), malathion etc. early at present, or makes the root zone application with the furans pellet.These residue of pesticide not only threaten the life and health of human body on paddy rice, and feeding animal contain the rice straw of agricultural chemicals, also can be in animal body residual, and then the life and health that threatens human body indirectly.
Summary of the invention
Technical problem to be solved by this invention is to provide the botanical pesticide of a kind of nontoxic, non-harmful control rice fulgorid.
In order to address the above problem, technical scheme of the present invention is: a kind of botanical pesticide of preventing and treating rice fulgorid, make by the method for being prepared as follows by the plant material of following parts by weight:
45～55 parts of China tree cotyledons, 40～50 parts of Chinese wingnut leafs, 0.8～1.2 part in Chinese prickly ash
The China tree cotyledon of said ratio, Chinese wingnut leaf and Chinese prickly ash are added the water of 2～3 times of weight, be heated to 90～95 ℃, decocted 15～20 minutes, filter and remove residue is collected decoction liquor, must liquid pesticidal after the cooling.
In the technique scheme, also the decoction liquor of collecting can be continued decocting and concentrating to 1/20～1/30 of original volume, get the concentrated liquid agricultural chemicals, just can use behind the dilute with water like this.
In the technique scheme, described China tree cotyledon and Chinese wingnut leaf are bright leaf, also can be cured leaf.
Raw material of the present invention, China tree cotyledon and Chinese wingnut leaf have strong desinsection and bacteriostasis, the pepper volatile oil that contains in the Chinese prickly ash is to stronger (the insecticidal activity research of supercritical CO 2 extraction pepper volatile oil of the ability of killing of insect, the 39th the 01st phase of volume of the journal .2005 of Agricultural University Of He'nan), the present invention is rationally formulated together with above-mentioned three kinds of raw materials, adding entry decocts, obtain liquid pesticidal, this agricultural chemicals has the stronger ability of killing to rice fulgorid, simultaneously the leaf roll snout moth's larva is also had certain ability of killing.
Through the agricultural experiment in 3 years, its result was as follows:
The present invention is sprayed about 35 jin according to every mu of rice field, or with 30 times of concentrated liquid agricultural chemicals dilute with waters, spray about 35 jin according to every mu of rice field again, after 3 days, rice fulgorid all kills, and the leaf roll snout moth's larva also reduces in a large number simultaneously, and output has improved 30～40%.
Compared with prior art, the invention has the beneficial effects as follows:
(1) control efficiency to rice fulgorid is good, simultaneously the leaf roll snout moth's larva is also had certain control efficiency;
(2) raw material is easy to get, and the preparation method is simple, and cost is low;
(3) nontoxic, noresidue can not damage humans and animals.
