Abstract
The present invention relates to a pesticide, particularly to a pesticide for killing coccid. The present invention has the preparing method that 2.5 to 7.5 parts by weight of tobacco stem and leaf and 0.1 to 0.4 parts by weight of rosin are added to 85 to 115 parts by weight of liquid caustic soda, are stirred and mixed, are boiled for 1 to 3 hours and are filtered; the filtered solution is delaminated and separated; the obtained filtered solution in the upper layer and the obtained filtered solution in the lower layer are respectively added with an organophosphorus agent; a first solution is obtained by emulsifying the solution in the upper layer with the ph value of 7 to 8; a second solution is obtained by activating the solution in the lower layer with the ph value of 11 to 13; when used, the first solution and the second solution of the same amount are mixed. The pesticide can effectively kill pests of coccid with the coccid killing effect of 90.5 to 98 %, and also has good killing effect especially on wax insects which are difficult to kill by common pesticides for killing coccid. Moreover, the pesticide of the present invention belongs to a low toxic pesticide, and therefore, the pesticide residue and the heavy metal amount in crops conform to the state standard of food sanitation after the pesticide is applied.
Description
Technical field
The present invention relates to a kind of agricultural chemicals, particularly kill the medicine of coccid.
Technical background
Coccid belongs to Homoptera Homoptera, Coccinea Coccomorpha, and a red-spotted lizard section, form is peculiar, asyngamy, male worm has 1 pair of film wing, and hind wing deteriorates to halter, digitus 1 joint.Female worm is aptery, digitus 1-2 joint, and the normal healing of 3 individual sections, the cephalothorax boundary is unclear, and the belly that has also merogenesis is unclear.The secretion of wax, colloid is often arranged, or special a red-spotted lizard shell protection is arranged.How they parasitize woody plant or herbaceos perennial with nymph, adult, all are food with water, and wherein many coccid kinds can be propagated the viroses of plant, are the fatal insects of important pest, especially gardening and forest.General coccid comprises that san jose scale, the hard a red-spotted lizard of ball, ceroplastes rubens, Ceroplastes japonicus Green, snake eye a red-spotted lizard, Kang Shi mealybug, tea oyster shell scale, long white a red-spotted lizard, ceroplastes, ellipse garden a red-spotted lizard etc. all have hard a red-spotted lizard shell or wax powder.Mainly comprise:
A: Margarodidae Monophlebidae: important representative insect has cottonycushion scale, giant mealy bug etc.
B: Pseudococcidae Pseudococcidae: common have tangerine stern line mealybug, a tangerine starch a red-spotted lizard etc.
C: the ancient type of banner hoisted on a featherdecked mast a red-spotted lizard Ortheziidae of section: common have a nettle ancient type of banner hoisted on a featherdecked mast a red-spotted lizard etc.
D: Lacciferidae Lacciferidae: be important industrial resources insect.
E: Diaspididae Diaspididae: small or small-sized, the microscler or garden shape shell of female body tool is slightly by wax; Male imago has wing or aptery, and the ommatidium of various numbers is arranged, and lancet is short and blunt, and the male imago feeler is thread, 10 joints, simple eye 4-6; Wing is arranged mostly; The no wax silk in abdomen end; Mating device long and narrow (as figure below); And it is maximum with Diaspididae pest species on the oranges and tangerines.Its important representative insect is unaspis shield kuwana and pears branch Aspidiotus---arrowhead scales and the san jose scale just often said.
F: wax coccidae (a red-spotted lizard section) Coccodae: the oval hemispherical of female adult worm wax shell, milky, there is an angle-like protrusion (as figure below) at the wax shell back side.It is with adult, nymph thorn phyllidium sheet, branch juice, and the branch growing way of being injured is weak, and blade is withered and yellow to come off.The host endangers plant except that fruit tree (citrus, pears, peach, apricot etc.), also endangers commodity trees, ornamental plantation trees and flower plants such as tea, mulberry.Common in addition have ceroplastes rubens, a Ceroplastes japonicus Green etc.And the white wax insect distinctive important product wax resource insect that is China is distributed in each province on the south the Qinling Mountains, and host plant is ash tree and glossy privet etc., and the insect of the tool representative of wax coccidae is a ceroplastes, also is the most obstinate in the coccid, the insect of difficult control; Especially the secretion of ceroplastes also can bring out generations such as sooty mould.
The at present known medicine that is used to kill coccid (general refer to arrowhead scales, san jose scale, ceroplastes rubenses on the citrus) has 25% excellently to readily take the opportunity to 95% machine oil emulsion that wetting powder, 40% omethoate emulsifiable solution, local method prepare and rosin mixture etc. more, they to 2 age nymph and 3 ages above adult killing effect respectively between 76.5%-97% and 69.8%-90.5%, but to the ceroplastes on the tea tree---also claim the killing effect of wax insect only be 2 age nymph 61.4%-82.5%, 3 ages, above adult 60.6%-72.5% did not reach the control requirement.This mainly is because ceroplastes (has another name called the angle wax insect, being commonly called as wax insect) host (is object with the harm tea tree mainly extensively, also endanger citrus, peach, Lee, cape jasmine, fruit tree, flower and plants such as Ficus microcarpa), particularly it can secrete one deck thick layer wax along with the polypide increase, as silk cocoon polypide is wrapped up, therefore, general medicine is difficult to infiltration and enters, conventional deinsectization method only takes to use systemic insecticide (excellently readily taking the opportunity to and medicine such as omethoate emulsifiable solution as above-mentioned), the plant juice of sucking the band medicine by insect plays toxic action, but effect is still undesirable.Another way is exactly by artificial physics mechanical curettage or cut off by the harm branch, and is so both time-consuming, and can not thoroughly remove harm again.
Summary of the invention
The purpose of this invention is to provide a kind of medicine of killing coccid,, particularly improve killing effect ceroplastes effectively to kill eliminating coccids-line pests.
The medicine of killing coccid of the present invention is got by following method preparation:
To mix in 2.5～7.5 weight portion tobacco stem and leaf and 0.1～0.4 weight portion rosin adding, 85～115 weight portion liquid caustic sodas, infusion was filtered after 1～3 hour, filtrate is carried out centrifugal layering, it is upper and lower two-layer that it is divided into, and separate, 40% omethoate emulsifiable solution or 80% dichlorvos or 95% dimethoate emulsifiable concentrate are added respectively in the upper and lower metafiltration liquid of gained, the Ph value that makes upper solution is 7～8, get solution A through emulsification, the Ph value of lower floor's solution is 11～13, the activated solution B that gets, solution A, the B with equivalent mixes in use.
It is 30～45% that described liquid caustic soda contains concentration sodium hydroxide.
The weight portion proportioning of described liquid caustic soda, tobacco stem and leaf, rosin is:
Liquid caustic soda 100
Tobacco stem and leaf 5
Rosin 0.25.
The infusion time of described liquid caustic soda, tobacco stem and leaf, rosin is 2.5 hours, and temperature keeps 100 ± 2 ℃.
Tobacco stem and leaf is exactly that the old cane of discarded native cigarette that burns as bavin of peasant or flue-cured tobacco is or/and old tobacco leaf.
During use, above-mentioned solution A, B mixed dissolving by 1: 1: 180～250 volume ratio with water, now with the current.
This medicine has carried out acute toxicity experience of animal per os and the test of skin primary stimulus by Huaxi Medical Univ:
One, content of the test
Medicine of the present invention is to the per os acute toxicity experience of big white mouse and small white mouse with to the irritant test of rabbit skin with eye.
Two, experimental technique
1, per os acute toxicity experience: select healthy Kunming kind small white mouse and SD big white mouse male and female half and half of just growing up, the design of HoronShi method is pressed in experiment;
2, rabbit skin primary stimulus experiment: select 6 of healthy Bai Maoxin southwest rabbits, cut both sides, light back, this medicine stoste and 1% dilution are done the patch experiment respectively by hair;
