Integrated Disease-Pest Management Program for Rice Fields in Africa

Application Scenario:

In the main rice-producing areas of Senegal, due to the concurrent occurrence of rice blast disease (incidence rate >40%) and the rice stem borer (dead heart rate >15%), farmers rely on highly toxic organophosphorus pesticides, leading to excessive pesticide residues in the soil and posing a threat to the ecology of the Niger River.

Technical solution:

Desheng Chemical provides integrated pharmaceutical and fertilizer granules:

bactericide:

30% Isoprothiolane and Kasugamycin suspension concentrate exerts its dual antibacterial mechanism through:

Isoprothiolane inhibits the synthesis of melanin in pathogens, while kasugamycin interferes with protein synthesis;

The inhibition rate of spore germination of Pyricularia oryzae reached 99.2% (compared to 85.6% for the control agent).

Insecticide:

20% chlorfenapyr and thiamethoxam granules adopt systemic conduction technology:

Chlorfenapyr activates the ryanodine receptor of pests, while thiamethoxam acts on the nicotinic acetylcholine receptor;

After 7 days of treatment, the mortality rate of the larvae of the rice stem borer reached 97.8%, with a duration of efficacy of 30 days.

Environmental protection features:

The granules utilize a degradable starch carrier that decomposes completely in the soil within 3 months, meeting the FAO green pesticide standards.
