Description
Technical field
The present invention relates to farm-forestry crop prevention and control of plant diseases, pest control field, concrete, relate to a kind of containing natural
Pyrethrin and the composition pesticide of Buprofezin and application thereof.
Background technology
Chemical pesticide the highest poison high residue synthetic organic pesticide product presently, there are and makes in a large number
By the problem with unreasonable use, this causes utilizing synthetic organic pesticide product protection crops
While stable and high yields, also inevitably result in ecological environmental pollution, agricultural product pesticide residual
Stay exceed standard, the series of problems such as harmful organism Drug resistance increase.For these serious problems, people
To research and application exhaling efficient, low toxicity, the less-persistent pesticide of eco-friendly
Sound day is the most surging.Natural pyrethrum is that can directly to process the drug effect of use at present ideal
One of plant source (biological) pesticide, insect is had excellent contact efficacy, quick-acting is good,
But due to the photo-labile of natural pyrethrum, cause its lasting period shorter, therefore overcome it to hold
Effect property is not enough has become the key that natural pyrethrum uses in farmland.Buprofezin is a kind of heterocycle
Class Chitin synthesis inhibitor, is synthesized by suppression chitin and interference metabolism, broken
The newborn epidermis of bad insecticide is formed, and makes insect normally not cast off a skin and abnormal and gradually dead；No
Kill adult, but can reduce and lay eggs and hinder egg hatching；Have tag, stomach poison function strong, tool oozes
Property thoroughly；There is high activity, high selectivity, the feature in the long longevity of residure, kill for novel high selectivity
Worm agent.Buprofezin has excellent safety in utilization and Environmental compatibility, but weak point is speed
Effect property is the most preferable.Natural pyrethrum (pyrethrins): in the spending of Herba et Flos Pyrethri Cinerariifolii
Six kinds of material compositions with insecticidal activity of extraction, it is mainly composed of pyrethrin I He
Ⅱ.Natural pyrethrum belongs to never poison, have tag, stomach toxicity and repellent action, can be right
Insect peripheral nervous system, central nervous system and other organ-tissues work simultaneously, use
Concentration is low, acts primarily as action of contace poison, therefore power of knocking down insect is strong, good disinsection effect, insecticidal spectrum
Extensively.Natural see that light slowly resolves into water and CO except centautin, therefore the pesticide prepared with it or health
After agrochemical use, noresidue is to people and animals' low toxicity, to plant and Environmental security, is internationally recognized
Safest pollution-free natural insecticide.

5 results and analysis
Natural pyrethrum wettable powder with buprofezin 1 prevents and treats the field efficacy of rice hoppers
Result of the test is shown in Table 7:
Table 7
Biological statistical method:
The biometrics of this test of pesticide effectiveness uses DPS (Data Processing System) soft
Part, its Notable difference test uses the new multipole of Deng Kenshi poor (DMRT) method.
Evaluating drug:
As can be seen from Table 7, the using dosage of natural pyrethrum wettable powder with buprofezin 1
For 25-30g/ mu [75-90g (a.i.)/hm2] or be diluted to 2000-2400 times of liquid Oryza sativa L. rice is flown
The prevention effect of louse is good, and after its medicine, the preventive effect of the 3-10 days is 83.2%-94.1%, and the lasting period is
More than 10 days.After medicine the 1st day, the prevention effect of its 20g/ mu with compare medicament 25% thiazine
Ketone wettable powder is diluted to the preventive effect of 3000 times of liquid (20g/ mu) and quite and substantially less than compares
Medicament 5% pyrethrin missible oil is diluted to the preventive effect of 1000 times of liquid (60mL/ mu), its 25g/
The prevention effect of mu is quite significantly higher than 25% Buprofezin with the preventive effect of 5% pyrethrin missible oil
The preventive effect of wettable powder, but the prevention effect of its 30g/ mu is then significantly higher than two kinds of comparison medicaments
Preventive effect；After medicine the 3rd day, the prevention effect of its 20g/ mu was substantially less than two kinds of comparison medicaments
Preventive effect, the preventive effect that the prevention effect of its 25g/ mu compares medicament with two kinds is suitable, but its 30g/
The prevention effect of mu is then significantly higher than the preventive effect of two kinds of comparison medicaments；After medicine the 5th day, its 20g/
Mu prevention effect be substantially less than two kinds comparison medicaments preventive effects, the prevention effect of its 25g/ mu with
Preventing of the preventive effect of 5% pyrethrin missible oil quite and substantially less than 25% wettable powder with buprofezin
Effect, but the prevention effect of its 30g/ mu is then significantly higher than the anti-of comparison medicament two kinds comparison medicament
Effect；After medication the 10th day, the prevention effect of its 20g/ mu was significantly higher than 5% pyrethrin breast
Oil preventive effect and the preventive effect of substantially less than 25% wettable powder with buprofezin, the preventing and treating of its 25g/ mu
Effect is quite significantly higher than 5% pyrethrin breast with the preventive effect of 25% wettable powder with buprofezin
The preventive effect of oil, but the prevention effect of its 30g/ mu is then significantly higher than the preventive effect of two kinds of comparison medicaments.
As a whole, natural pyrethrum wettable powder with buprofezin 1 is to preventing and treating rice hoppers
Quick-acting is good and the lasting period is longer.
Natural pyrethrum wettable powder with buprofezin 1 to rice crop without any poisoning, right
Its leafhopper, thrips etc. have the most double controls effect, natural enemy (the predatism spider to rice grub
Spider, nibble chalcid fly, ground beetle, rove beetle etc.) also affect less.
