Description
Technical field
The present invention relates to technical field of pesticide, and in particular to a kind of Thidiazuron defoliant composition containing diquat dibromide.
Background technique
Thidiazuron is a kind of plant growth regulator with cytokine activity, can with induced tissue grow with again
It is raw, while it being very effective a kind of cotton defoliant, its non-degradable chlorophyll does not change the flow of water of blade, does not injure directly
Blade can but promote the generation of ethylene, inhibit the transport of auxin, reduce the ratio of auxin and ethylene.Plant by pair
The intense adjustment of the sensibility of Ethylene Signal adjusts and the processes such as receives to Ethylene Signal, regulates and controls falling off for organ with this.Thiophene benzene
The mechanism that grand inducer blade falls off achievees the purpose that leaf abscission indeed through the level for influencing ethylene in plant.
Diquat dibromide is a kind of excellent contact desiccant and the herbicide with interior suction property, and main mechanism is suppression
The photosynthesis of plant processed is photosynthetic electron transport chain diversion agent.Diquat dibromide acts on plant in addition to participating in fighting for photosynthesis
Electronics, prevent outside the reduction and subsequent reactions of ferrodoxins, to weeds generate toxic action the main reason for be it
Unsaturated fatty acid will lead in biomembrane by the product of electron reduction and generate peroxidation, biolytic semi permeability and make
At the death of cell.
Either Thidiazuron or diquat dibromide, the usage history of all existing decades, in extensive application, due to pesticide
Abuse, the resistance that Target crops generate in succession, peasant use larger dose to apply, in turn result in improve function and effect
Target resistance stronger vicious circle.So chemical agent subtracts the research hotspot applied be in recent years.
Currently, not yet there is the relevant report of Thidiazuron and diquat dibromide synergy research.

Specific embodiment
The present invention will be described below by way of specific embodiments, but the present invention is not limited thereto.
Experimental method used in following embodiments is conventional method unless otherwise specified；Institute in following embodiments
Reagent, material etc., are commercially available unless otherwise specified.
Diquat dibromide mother's medicine is purchased from Shandong Weifang Rainbow Chemical Co., Ltd.；Thidiazuron raw medicine is purchased from Anyang rich biology entirely
Science and Technology Ltd..
The preparation of embodiment 1, Thidiazuron diquat dibromide suspending agent
Thidiazuron 19%, diquat dibromide 1%, alditol 1%, polyoxy alkylbenzene ether-ether phosphate 4%, propylene glycol 10% are yellow fast
Purine 0.25%, poly- alkyl polysiloxane 0.05%, water 63.7%, using wet pulverizing until average grain diameter reaches volume and is averaged grain
3 ± 0.5 μm of diameter, obtaining effective component is 20% Thidiazuron diquat dibromide suspending agent.
The preparation of embodiment 2, Thidiazuron diquat dibromide wettable powder
Thidiazuron 18%, diquat dibromide 2%, lauryl sodium sulfate 2.6%, sodium lignin sulfonate 6.5%, white carbon black
2.1%, kaolin 35%, diatomite 31.8%, crushing, effective component is made after mixing is that 20% Thidiazuron diquat dibromide is wettable
Property pulvis.
Embodiment 3,
Test setting: Thidiazuron is compounded by a certain percentage with diquat dibromide, effective component ratio (Thidiazuron: diquat dibromide) is made
Always have for 7 kinds of Thidiazurons such as 100:0,100:0.4,100:1,100:3,100:5,100:10,100:20 or Thidiazuron, diquat dibromide
The pesticide defoliant composition that content is 20% is imitated, by 60ml/ mus of preparation dosage, 30L/ mus of spouting liquid in spraying on cotton, as a result
It is shown in Table 1.
1 20% Thidiazuron complex composition of table application effect on the cotton
Note: in practical applications, cotton leaf quantity is dynamically that the cotton maturity period may also have new leaf growth to go out
Come
From the data in table 1, it can be seen that a certain amount of diquat dibromide is added and shows significantly compared with being applied alone Thidiazuron to carry out disleave
Synergistic effect.After being administered 25d, Thidiazuron: the mass ratio of diquat dibromide is the composition of 100:1,100:3, defoliation effect
Than being applied alone Thidiazuron to be increased slightly, Thidiazuron: the mass ratio of diquat dibromide is the composition of 100:5, and thiophene is applied alone in defoliation effect ratio
Benzene is grand to increase by 7.3%, and Thidiazuron: the mass ratio of diquat dibromide is the composition of 100:10, and defoliation effect is optimal, than thiophene benzene is applied alone
Grand increase by 14.4%, and Thidiazuron: the defoliation effect specific mass ratio for the composition that the mass ratio of diquat dibromide is 100:20 is 100:
The effect of 10 composition is slightly poor.In conclusion Thidiazuron: composition disleave of the mass ratio of diquat dibromide in 100:1-100:10
Effect increases obvious.
