It can be used for control through evidence; Rice; Rice fulgorid, rice Echinococcus hydatid cyst, borer.Wheat; Wheat sawfly, aphid inhales the slurry worm, two spotted spider mite.Cotton; Cotton bollworm, cabbage caterpillar, thrips, cotton blind spring, prodenia litura, tetranychid.Forest; Yellow mealworm, chafer, heart-eating worm, leaf roller, the bark worm is set peppery worm, weevil worm, wild silkworm, caterpillar, rhizome, root knot, packing, pine wood nematode, cutworm.Wherein spray extension rate; 800---1000 doubly.The center separating tests of at present giving an example is following:
One, control root knot silk ribbon for holding a jade seal through its nose worm biological activity determination:
1, supply the reagent agent: medicine embodiment 1-6 of the present invention converts 9 times of water, calls medicine of the present invention in the following text.
2, supply the examination material: tomato root-knot eelworm [Meloidegyne incognita Chitwood]
3, test method: line taking worm soil sample mixing from the greenhouse takes by weighing 200 gram soil samples and packs into for use in the 1000mL wide-mouth bottle.
Take by weighing medicine 8g of the present invention, 49,2g, 1g, 0.5g respectively; Evenly join respectively in the wide-mouth bottle that installs nematode soil, mix, cover tight bottle cap; Put into 27-28 ℃ incubator; Take out after 72 hours, nematode in the soil is separated. and establish not dosing as blank, every processing repetition 3 times.
The nematode separating method adopts centrifugal floating method. and be about to the 200g soil sample and put into the 1000ml beaker; Add about the about 1000ml of water; Firmly stir soil block is disperseed; After the sedimentation 30 seconds, top suspension is poured in second beaker through 50 purpose sieves. after static 1 minute, supernatant in second beaker is passed through 400 purpose mesh screens; Put in the centrifuge tube mixture flushing in the mesh screen centrifugal with 2000r/min. remove the supernatant in the centrifuge tube, nematode retains in the pipe residue sediments at the end. and it is centrifugal again in the centrifuge tube that the concentration of reinjecting is 38.5% sucrose solution.Get suspension and sieve, then the investigation counting.
Result of the test is seen table 1: the control efficiency of table 1 medicine embodiment 1 of the present invention
It is visible more than to measure the result, and medicine of the present invention has good biologically active to tomato root-knot eelworm.The embodiment of the invention 2 is identical with embodiment 2 result of the tests, and the result of the test of embodiment 3-6 and embodiment one no significance difference, the Therefore, omited.
Two, control brassicaceous vegetable cabbage caterpillar field control effectiveness test
Wild cabbage: controlling object cabbage caterpillar (reed ierisrapae)
Test medicine: medicine embodiment six of the present invention converts 9 times of water; Beta-cypermethrin 4.5EC.
Test is handled:
1, sanguinarine 300g/mu in the medicine of the present invention
2. sanguinarine 500g/mti in the medicine of the present invention
3. sanguinarine 700g/mu in the medicine of the present invention
4. beta-cypermethrin 4.5EC 30g/mu:
5. clear water contrast
Test method and situation: sub-district and long-pending about 20m2 repeats 4 times, randomised block design, isolation strip is established in the minizone.
November 17 is with workers and peasants' one 16 type knapsack sprayer even spraying, mu spraying volume 45 liters of (675L/hm2) these duration wild cabbage heading stages and cabbage caterpillar young larva phase.
Shi Yueqian respectively looked into field worm amount in 3,7,10 days one time from executing about back.Each sub-district is fastening 5 points at random, and the borer population of living it on is investigated in every fixed 5 strains at every turn, record and calculating insect population go down rate and preventive effect.
Dispenser was fine to cloudy the same day, 9～20 ℃ of temperature, 15 ℃ of mean temperatures, relative moisture 69%.The duration of test minimum temperature is 5-10 ℃, and maximum temperature is 10--22 ℃,, relative moisture is at 65---86%.November 25 light rain, rainfall is 10mm, all the other are fine day.
Result of the test shows:
1. each handles medicine of the present invention and all can prevent and treat field cabbage caterpillar larva preferably, and suppresses it and cause harm. The preventive effect of handling most with high, middle agent in three processing is better, and 7 days preventive effect is respectively 87.88%, 82.88% after the dispenser, and 10 days anti-putting is respectively 93.35%, 88.17% (table two) after the dispenser.
2, it is close that the control efficiency of beta-cypermethrin 4.5EC and the low dosage of medicine of the present invention are handled control efficiency, and 7,10 days preventive effect is respectively 78.04%, 82.06% (table two) after the dispenser.
3. wild cabbage does not have poisoning.
4. " DMRT " measures the result and sees table two respectively to handle after the dispenser 10 days preventive effect.
In sum, we think that medicine of the present invention is the better medicament of control cabbage caterpillar, and its preventive effect is high, and to wild cabbage safety, the lasting period can be about 10 days.Annotate: parallel result of the test and not significantly difference of embodiment six that embodiment of the invention 1-5 does according to said method, Therefore, omited.
