Description
Technical field
The invention belongs to insecticides technical field, more particularly to a kind of insecticides containing flubenzuron and
Its application in pest control.
Background technology
The use of pesticide has very long history, and huge effect has been played in the process of mankind's nature remodeling,
The great development of agricultural is promoted, huge economic benefit is brought to the mankind.China is in B.C. seventh century to B.C. fiveth century
Pest is killed with thick grass, clam charcoal ash, male bring up etc..It is with natural drug and inorganic compound pesticide before the 1940s
Based on natural and inorganic drug epoch；Since early in the twentieth century, into the epoch of synthetic organic pesticide.The hair of pesticide at present
Spread gesture：Developed country has been enter into Cultivar replacing from the seventies in last century and regenerates, and China's pesticide is begun with from the eighties in last century
Large development, but it is most of establish and grow up on the basis of imitated, until the nineties China's pesticide species just start more
Newly.But pesticide is still based on old kind, and be wherein leading, pesticide species ratio reasonability using high poison, persistent pesticide
It is poor, it is relatively low using technical merit, and dosage is big, it is serious so as to cause environmental pollution.It is actual in the 21st century, agricultural production
The pesticide of application is gradually to toxicity is low, active high, the good direction of Environmental compatibility is developed.
Toxicity and its side effect due to pesticide so that there is a series of problem in the long-term use in pesticide,
For example, toxicity of pesticide residual, environmental pollution, ecological balance destruction etc..However, pesticide is still essential production money at present
Material, because this is related to and how to solve world population and increase rapidly, to the active demand problem of agricultural product, therefore it is necessary to develop
The agricultural of high-yield and high-efficiency rather than the organic agriculture for taking low yield, and pesticide is the necessary guarantee of high-efficiency agriculture.
Pest resistance to insecticide is one of important factor in order that Pesticide use effect is influenced in the real process of agricultural production,
Pest resistance to insecticide refers to generate certain insecticide medicine resistance ability using pest after insecticide, and this due to the use of killing
Medicine resistance ability caused by worm agent hereditary can go down.Due to chemical pesticide it is long-term, be excessively used, in certain a kind of chemistry
Pesticide use for a period of time after, usual pest all can generate resistivity to this kind of medicament to a certain extent.From species of insect pests
From the point of view of class, the resistance to the action of a drug most species of coleoptera, Diptera and lepidopterous insects generation, wherein aphid, bollworm and mite class
The resistance to the action of a drug is the most serious.
The crop yield influences such as the resistance to the action of a drug of pest can cause agricultural output to decline, farm production cost increases, Pest rampancy,
Due to increasing pesticide, can also irreversible harm be brought to the mankind and environment.In order to solve the problems, such as pest resistance to insecticide, it is necessary to
It develops new drug or selection compounds different insecticides, to reach required drug effect.

The test of pesticide effectiveness
Inventor is also respectively by the insecticide composition containing flubenzuron of the particular dosage form prepared in embodiment 4,6,7 and 9
Object has carried out prevention bollworm, the test of pesticide effectiveness of beet armyworm, and result of the test is as shown in the following table 3~4：
3 embodiment of the present invention of table is with 25% flubenzuron for the preventive effect table of comparisons of beet armyworm
| Medicament | Dosage g.ai/ha | 7 days preventive effects, % | 15 days preventive effects, % |
| Embodiment 4 | 90 | 85.8 | 91.7 |
| Embodiment 6 | 60 | 87.5 | 94.7 |
| 25% flubenzuron SC | 60 | 81.4 | 86.5 |
4 embodiment of the present invention of table is with 5% flubenzuron for the preventive effect table of comparisons of bollworm
| Medicament | Dosage g.ai/ha | 7 days preventive effects, % | 15 days preventive effects, % |
| Embodiment 7 | 30 | 90.4 | 96.4 |
| Embodiment 9 | 30 | 91.5 | 95.8 |
| 5% flubenzuron EC | 30 | 86.6 | 90.3 |
Analysis of experimental results：
1) as shown in table 3, the dosage of the insecticides in the embodiment of the present invention 4 is 90g.ai/ha, and embodiment 6
And 25% the dosage of flubenzuron SC be 60g.ai/ha.Three experimental groups shown in table 3 are to 7 days preventive effects of beet armyworm
85.8%, 87.5%, 81.4% is followed successively by, and the preventive effect of 15 days is followed successively by 91.7%, 94.7%, 86.5%.
It can be seen from the above, the dosage of the insecticides described in embodiment 6 is only 60g.ai/ha, but its 7 days and
4 and 25% flubenzuron SC of embodiment is significantly better than that within 15 days to the preventive effect of beet armyworm；And embodiment 4 prevents beet armyworm
Effect is also more excellent than 25% flubenzuron SC.
Therefore, the insecticides compounded in embodiment 4 and embodiment 6 are anti-to 7 days preventive effects of beet armyworm or 15 days
Preventive effect when effect is superior to using single insecticide flubenzuron.
2) as shown in table 4, the embodiment of the present invention 7,9 and the dosage of 5% flubenzuron EC are 30g.ai/ha, three in table 4
A experimental group is followed successively by 7 days preventive effects of bollworm 90.4%, 91.5%, 86.6%, the preventive effect of 15 days is followed successively by 96.4%,
95.8%th, 90.3%.
It can be seen from the above, embodiment 7 and the insecticides compounded in 9 are suitable to the preventive effect of bollworm, it is apparent excellent
Preventive effect when 5% flubenzuron EC is used alone.
In conclusion the present invention by containing 4- to the 1,3-dioxolane class compound of phenoxy-phenoxy methyl structural with
Therefore the drug effect for the insecticides that flubenzuron is compounded, is used apparently higher than preventive effect when using single-dose product
Less dosage can achieve the effect that desinsection, so as to substantially reduce the resistance risk of pest.
Specific embodiments of the present invention are described in detail above, but it is intended only as example, it is of the invention and unlimited
It is formed on particular embodiments described above.To those skilled in the art, it is any to the equivalent modifications that carry out of the present invention and
It substitutes also all among scope of the invention.Therefore, the impartial conversion made without departing from the spirit and scope of the invention and
Modification, all should be contained within the scope of the invention.
