Background technology
Fertilizer and pesticide occupy an important position in agricultural production, and the nutrient demand that fertilizer can provide plant growth ensures to increase
Production, increases income；Pesticide can effectively prevent curing the disease, worm, crop smothering, escort for crop normal growth.The development trend of fertilizer is compound, special
With, sustained release, it is multi-functional；The requirement of pesticide is that efficient, less toxic, wide spectrum, lasting period long utilization rate are high.Fertilizer, pesticide, soil and work
There is direct or indirect relationships between object.With the development of agricultural production, the continuous improvement of scientific and technological level, fertilizer,
Combined use of pesticides makes two, field operating procedure be combined into one, and existing oneself becomes an important development direction of agriculture field.Medicine fertilizer exists
The research in China starts from the 1980s, having more research at present, but the research of slow releasing medicinal fertilizer is also fewer.Slow releasing medicinal fertilizer
Maximum feature be that fertilizer, the release of pesticide are synchronous with the absorption that plant growth needs, it is whole to realize that single fertilization meets crop
The needs in a growth period save labour, time, the energy, reduce production cost, and the antagonism that can avoid between pesticide, fertilizer is made
With and to crop harmful effect, increase the synergistic effect between them, reduce the dosage of pesticide and fertilizer, obtain best answer
With effect, to environmental protection, the yield of crop is improved.
Dinotefuran is developed earliest by Mitsui chemical company, the third generation nicotinic insecticide listed in 2002.
The medicament insecticidal spectrum is wide, has remarkable interior suction osmosis, and show very high insecticidal activity in very low dosage.It should
Medicament is fool proof to mammal, birds and aquatile, to crop without poisoning, to numerous crops such as rice, fruit tree, vegetables
On Homoptera, Lepidoptera, Diptera pest have efficiently.Dinotefuran sustained release fertilizer granules are not prepared into existing literature

Acid esters, remaining is constant.
Test one：Preparation physical property is tested
The performance indicator of fertilizer granules prepared by the application is measured using this field traditional test methods.Heat storage stability
It is measured according to method in GB/T19136-2003；Persistent foamability is carried out according to GB/T28137-2011.
1 preparation physical property of table is tested
As shown in Table 1, compared with comparative example 1-3, embodiment 1-3 in persistent foamability, dust index with compare indifference
It is different；The heat storage stability of embodiment 1-3 is significantly better than the heat storage stability of comparative example 1-3, i.e., the selection of cyst material is to activity
The stability of ingredient is by large effect.It can be seen that for dinotefuran fertilizer granules, 2,4- toluene di-isocyanate(TDI)s are selected
Or the cyst material that 2,6- toluene di-isocyanate(TDI)s and ethylenediamine are formed is better than the group for selecting other isocyanates and ethylenediamine
Close object.
Test two：Field efficacy of the fertilizer granules to rice grub
Controlling object：Rice hoppers, rice leaf roller, striped rice borer
Pesticide control：Medicament prepared by the embodiment of the present application 1-3 and comparative example 1-3, same dose.
Using drug mode：It is applied using fertilizing type.
Field efficacy of 2 fertilizer granules of table to rice grub
Dynamic is presented in generation of the pest in field, and after drug effect disappears, pest will just infect crop again, therefore improve medicine
The lasting effect of fertilizer can effectively reduce medicine fertilizer application times.As shown in Table 2, the lasting effect of embodiment 1-3 fertilizer granules is obviously good
In the lasting effect of comparative example 1-3, embodiment 1 is 44.3% to 60 days preventive effects of planthopper, and comparative example is only 22.4%；Embodiment
60 days preventive effects of 2 pairs of rice leaf roller are 60.1%, and comparative example is only 41.7%；Embodiment 2 is to 60 days preventive effects of striped rice borer
42.8%, comparative example is only 26.1%.It can be seen that for dinotefuran fertilizer granules, select 2,4- toluene di-isocyanate(TDI)s or
The sustained release performance for the cyst material that 2,6- toluene di-isocyanate(TDI)s and ethylenediamine are formed, which is substantially better than, selects other isocyanates
With the combination of ethylenediamine.
Further narration is done to the present invention above in conjunction with embodiment, but present invention is not limited to the embodiments described above,
One skilled in the relevant art within the scope of knowledge, can also make without departing from the purpose of the present invention
Various change.
