Technical Field

[0001] The present invention belongs to the technical field of pesticide compounding, and particularly relates to a pesticide composition containing feneptamidoquin and application thereof. Background Art

[0002] Rice blast, caused by the fungus Phyricularia gisea of ​​the Deuteromycetes (also known as gray pear spore, the sexual form of which is Magnaporthe grisea), is a major threat to rice production stability, quality, and safety in rice-growing areas worldwide. Severe damage can lead to a 40% to 50% yield reduction or even total crop failure.

[0003] For a long time, pesticide control has remained the most rapid and effective measure for preventing and controlling rice blast. However, due to the mutation of the rice blast fungus and the irrational use of chemical pesticides, the problem of pesticide resistance has become increasingly serious in rice production, resulting in a significant decline in the effectiveness of pesticides against rice blast in the field. Therefore, new pesticides are urgently needed to prevent and control rice blast in rice production and provide a guarantee for the prevention and control of this disease.

[0004] The development of novel, highly effective fungicide combinations combining fungicides with different mechanisms of action is crucial for overcoming and delaying bacterial resistance, reducing pesticide dosage, effectively controlling the damage caused by rice blast, and ensuring stable and high rice yields. This study used a mycelial growth rate method to determine the indoor toxicity of different mixtures of feneptamidoquin with pyraclostrobin and pyraclostrobin against the rice blast fungus. The combined action patterns of the mixtures were analyzed, and field trials were conducted to evaluate the efficacy of selected mixtures against rice blast, aiming to provide technical support for the prevention and control of rice blast and the management of pesticide resistance.

Measure each colony twice and take the average value.

[0096] Classification records are made according to the following classification method:

[0097] Level 0: no disease;

[0098] Level 1: Loss of less than 5% per ear (individual branches and stalks are affected);

[0099] Level 3: 6% to 20% loss per ear (about one-third of the branches and stalks are diseased);
