Cultivation, belongs to technical field of plant protection.
Background technology
Tomato spotted wilf virus (Tomato spotted wilt virus) is a kind of important phytopathy for endangering agricultural production
Poison.Tomato spotted wilf virus is different from the diseases such as fungi and bacterium as a kind of arbovirus disease propagated by thrips, prevention and control
Prevention, spotted wilt virus should be controlled in itself, control the sprawling of virus disease and stream by controlling mediator insect thrips again
Row, control strategy are complicated, difficult.As Tomato in Greenhouse Main Cultivation crops for rotation, autumn delay tomato spotted wilf virus disease is non-
Chang Yanchong.
It still relies primarily on through the chemical prevention to mediator insect thrips to realize the prevention of spotted wilt virus in production at present
With control, and the unreasonable using even abusing of pest control with insecticide medicament is caused, and then cause pest resistance to insecticide, pesticide pollution
The problems such as with residual, the great society and economy problem such as serious threat agricultural product security and ecological safety and the export of farm produce.
Meanwhile the common fly net with good ventilation effect is difficult to obstruct thrips disengaging greenhouse at present.Using not less than
