When sunflower pest control was

Sclerotinia control involves several key steps. First, a single round of soil dumping is applied to reduce the pathogen load. For seed treatment, uncoated seeds are dressed with 3% of a 50% carbendazim wettable powder solution. Soil treatment includes mixing 250 grams of 50% carbendazim wettable powder per mu with fine sand and composted soil before sowing. Planting is done in wide and narrow rows, with 80 cm between wide rows and 40 cm between narrow rows. Spacing between plants varies: about 40 cm for edible sunflower varieties and 25 cm for oilseed types. During the sclerotial blastocyst period, a mixture of 350 grams of 50% carbendazim WP or Sicilian WP per mu is combined with fine sandy soil and spread around the roots. For foliar application, early-stage infections are treated with 1500 times dilution of 50% carbendazim WP or 50% Sicilian WP, or 800 times dilution of 40% sclerotin net. For aphid control, adult aphids are managed using sex attractants and insecticidal lamps. Insecticides such as 10% diclofen EC diluted 1000 times or 40% chlorpyrifos EC at 800 times are applied in the evening. For larvae control before grain formation, 90% trichlorfon crystals at 500 times, 20% fenvalerate at 1000 times, or 4.5% beta-cypermethrin at 1500 times are used. Spraying should be repeated every five days or so. For disease resistance, variety "Anti-Lee Dang" is recommended. Crop rotation with grasses for at least six to seven years is advised. Before flowering and harvesting, fields are cultivated and weeded two to three times, followed by deep plowing or burning. Strict seed quarantine measures are essential to prevent the introduction of infected seeds from affected areas. For rust management, crop rotation and deep plowing are critical. Seeds should be treated with 25% hydroxycamptoluene WP, using 100 grams per 50 kg of seeds. Wide and narrow row planting helps improve air circulation, while regular cultivation and drainage reduce field humidity. Early spraying is crucial, with options like 15% triadimefon WP (1000–1500 times) or 50% rust rust EC (800 times). A second application is recommended every ten days to ensure effective control.
