According to the various embodiments described above the formulation material mixture is carried out as follows: will calculate the nimbin dry powder of good amount and brassin lactones and be dissolved in and mixing with first cyst material in the solvent, it is joined in the aqueous solution that contains emulsifier, add synergist, with efficient emulsification pretreatment machine mixed solution is well-dispersed in the aqueous solution, using magnetic stirrer instead adds second cyst material and carries out polymerisation, adjust pH to 6 continues to stir a period of time, promptly makes capsule.Filtration under diminished pressure, the dry brassin lactones nimbin micro capsule product that can make desired concn in vacuum drying chamber at last.
Brassin lactones nimbin micro capsule result of the test:
Test method 1: with concentration is that 4.01% brassin lactones nimbin micro capsule is diluted to 800 times, 1000 times, 1600 times, with 4% nimbin emulsion dilute same equimultiple, 0.01% brassin lactones aqua and the same equimultiple of other insecticide mixed dilutings, blank group is contrast.Object is a wild cabbage, and the dispenser phase is that cabbage caterpillar takes place to contain the phase for 3 ages.Adopt 5 point samplings, the preventive effect and the crop yield amount of the medicament after 7 days, 10 days, 15 days are made investigation, the result who gets 3 repeated tests adds up, and statistics sees the following form 1.
Table 1 brassin lactones nimbin micro capsule field sterilizing ability is measured
As can be seen from Table 1, brassin lactones nimbin micro capsule, nimbin and after brassin dilutes identical multiple respectively, the duration of efficacy of brassin lactones nimbin micro capsule is obviously longer, and is little to the injury of crop itself, and has remarkable result aspect the volume increase that promotes crop.
Test method 2: being mixed with 90% preparation with the nimbin raw medicine of the present invention preparation, is 10ppm with half times of dilution method with its concentration dilution.Adopt drop method to 3 age cabbage caterpillar carry out toxicity test, the lethality after 18 days reaches 90%, drop cabbage caterpillar food refusal in 4 age effect reaches 94%.
The brassin lactones nimbin micro capsule of producing 15% is diluted to 0.5% preparation, is 10ppm, 40ppm, 80ppm with half times of dilution method with its dilution again.Adopt drop method to 3 age cabbage caterpillar carry out toxicity test, the lethality after 18 days is respectively 36.4%, 56.8%, 85.3%.
Can see that by above-mentioned result of the test the brassin lactones nimbin micro capsule can effectively be prevented and treated cabbage caterpillar, and use low dosage can obtain preferable control efficiency, and the drug effect duration is long, is beneficial to the generation of long-term control insect.
