(3) summary of the invention
One of the object of the invention is to address the above problem, and provides effective, cost is low, residual low, the safe bactericidal composition that contains flutolanil and tpn.
Two of the object of the invention is above-mentioned composite bactericidal composition is used for the control of ornamental plant disease.
The objective of the invention is to realize like this:
A kind of bactericidal composition that contains flutolanil and tpn, said composition contains flutolanil and tpn, and the weight ratio of said flutolanil and tpn is 2~40: 3~60.
Preferably, the weight ratio of said flutolanil and tpn is 5~30: 8~40.
Said combination dosage form is any one formulation that allows on the agricultural chemicals.
Said combination dosage form is wetting powder, water dispersible granules, suspending agent, aqueous emulsion or missible oil.
When concrete the application, said flutolanil and the tpn mass percent in above-mentioned formulation is 5~90%.
A kind of purposes that contains the bactericidal composition of flutolanil and tpn is used for the control of ornamental plant disease.
The present composition can be used for rose anthracnose, powdery mildew, Moth orchid leaf spot, camellia sooty mould, Chinese rose powdery mildew, Indian fig rot, jasmine southern blight, common primrose basal stem rot, cajuputi pinta, money tree brown spot, closes fruit taro gray mold, red along green pepper blade of grass pinta, gardenia sooty mould, ginkgo basal stem rot, cypress leaf blight, add the control of ornamental plant diseases such as poplar rot, the broken look disease of pansy, the mould eqpidemic disease of scarlet sage.
The present composition is except that being applied to prevent and treat the ornamental plant disease; The disease that also can be used for crops such as cereal crop, various melon and fruit, vegetables; Like the control of crop pests such as paddy rice, wheat, tomato, banana, apple, pears, like rice sheath blight disease, wheat powdery mildew, early blight of tomato, alternaria leaf spot of apple, pear scab etc.
Compared with prior art, the invention has the beneficial effects as follows:
(1) present composition synergistic effect of in certain ratio range, doing well, the bactericidal effect of composition have had than single agent and have significantly improved, and have reduced agricultural chemicals using dosage, access times and cost simultaneously, to human and environment safety;
