Description
Technical field
The invention belongs to synergetic pesticide composition fields, and in particular to one kind containing active constituent psoralen and dimoxystrobin
Composition pesticide.
Background technology
Psoralen (Psoralen)), also known as psoralen, Methoxypsoralen, CAS accession number 66-97-7.Chinese patent
CN102067850A discloses purposes of the psoralen as agricultural bacteriocide or insecticide, and psoralen is from natural plants
It isolates and purifies to obtain or commercially available.
Dimoxystrobin (Dimoxystrobin) is methoxy acrylic bactericide, mitochondrial respiratory inhibitor, to more
Kind plant disease all has control effect such as rice blast, rice sheath blight disease etc..
It is one of prevention most effective chemical means of phytopathogen using chemical agent；With the novel pesticide of not cross resistance
It is a good solution to carry out controlling plant diseases；But one novel pesticide of exploitation needs to screen a chemical combination up to ten thousand at present
Object, hundred million dollars of cost 1.2-1.5, the development cycle is 5-10, it is difficult to the speed that the upper pathogen caught up with develops immunity to drugs；It is other
Method such as crop structure adjustment, different pesticide rotations etc., in actual mechanical process, it is difficult to play apparent effect.
Develop new product fungicide is expensive, the period is long, and in contrast, exploitation is efficient, less toxic, low-residual with research
Compounding have with mixture invest small, lead time it is short and by attention both domestic and external, it is numerous and confused to increase development dynamics.
The synergistic combination of psoralen and dimoxystrobin has not been reported, and the mechanism of action and effect of psoralen and dimoxystrobin are special
Point is different.
