3, chemical name: 1-[2-(2,4 dichloro benzene base)-4-propyl group-1,3-dioxolanes-2-methyl]-1-hydrogen-1,2, the 4-triazole.
Penconazole belongs to three nitrogen heterocycles bactericide, is sterol demethylation inhibitor.Root, stem, leaf isoreactivity tissue by crop absorb, and can upwards conduct with body fluid in the plant body soon.
The agent of penconazole list is used for a long time, and disease is developed immunity to drugs, and causes the problem that dosage strengthens, preventive effect reduces, the lasting period shortens, and is unfavorable for environment sustainable development.And that the active ingredient of the different mechanisms of action is carried out is composite, is to delay the disease method commonly used that develops immunity to drugs, and according to the effect in the production application, judge this composite be synergistic effect or antagonism.Complex role is more significantly filled a prescription, and can obviously improve preventive effect, reduces the dosage of agricultural chemicals greatly, also can enlarge fungicidal spectrum, improves germicidal efficiency.
Summary of the invention
The objective of the invention is to propose a kind of generation or delaying drug resistance speed that can prevent disease drug resistance, the composition pesticide that contains penconazole that use cost is low, preventive effect is good.
The inventor is by a large amount of indoor biometricses and field control effectiveness test, finds the use that is mixed within the specific limits of penconazole and triazole bactericidal agent unexpectedly, and diseases such as the powdery mildew of cereal crop, rust, glume blight are had good synergistic effect.Further experiment finds, the use that is mixed within the specific limits of penconazole and triazole bactericidal agent also has good preventive effect to spot defoliation, anthracnose, powdery mildew, leaf spot, the scab of vegetables and fruit tree.And the composite of penconazole and triazole bactericidal agent at home and abroad do not see openly as yet.
The composition pesticide that the present invention proposes contains two kinds of active components of A, B.
Active component A is selected from following any one triazole bactericidal agent: triazolone, Tebuconazole, own azoles alcohol, Flutriafol, alkene azoles alcohol.
