Uses of Pyrastak 45 SC in agricultural crops: Used to combat fungal diseases attacking leaves and vegetative parts, especially those spreading in humid conditions like late blight and powdery mildew. The product is especially important in crops that are quickly affected by disease spread, such as tomatoes, potatoes, cucumbers, and grapes. Main uses: Control of late blight in potatoes. Control of late blight in tomatoes. Control of powdery mildew in grapes. Control of powdery mildew in cucumbers. Used preventively before infection spreads under suitable conditions for fungi. Used therapeutically at the first appearance of symptoms. Protects the vegetative parts and reduces crop losses when used at recommended doses. To improve spray quality and solution distribution on leaves, suitable tools from the pesticide sprayers and pumps section can be used, or a small sprayer from the manual agricultural sprayers section. Method of using Pyrastak 45 SC according to crop: Pyrastak 45 SC is used by foliar spraying after dilution in water. The container should be shaken well before use, then the recommended dose is added to the spray tank after partially filling it with water, with continuous stirring, then the required amount of water is added while continuing to stir to ensure uniformity. Recommended doses for the product: Potatoes: used against late blight at 50 ml per 100 liters of water. Pre-harvest interval: 21 days. Tomatoes: used against late blight at 50 ml per 100 liters of water. Pre-harvest interval: 21 days. Grapes: used against powdery mildew at 50 ml per 100 liters of water. Pre-harvest interval: 10 days. Cucumbers: used against powdery mildew at 50 ml per 100 liters of water. Pre-harvest interval: 28 days. Important application instructions: It is preferable to use preventively before infection appears or at its early stages. The entire vegetative part should be covered for the best results. Spraying is recommended early in the morning or before sunset. Avoid spraying during high temperatures or strong wind. Do not increase the dose arbitrarily during severe infection. Do not repeat use alone in successive sprays. It is preferable to rotate with fungicides from different groups to reduce resistance risk. The pre-harvest interval should be strictly followed according to the crop. Pre-harvest intervals vary depending on the crop: Potatoes: 21 days. Tomatoes: 21 days. Grapes: 10 days. Cucumbers: 28 days. Full adherence to the pre-harvest interval according to the approved label instructions and relevant authorities is necessary, and harvesting should not occur before the specified period ends. Precautions and warnings when using Pyrastak 45 SC: Read the entire product label before use. Follow the doses and pre-harvest intervals specified for each crop. Wear gloves, mask, goggles, and protective clothing during preparation and spraying. Avoid contact of the fungicide with skin, eyes, or inhalation of spray mist. Do not eat, drink, or smoke during use. Avoid spraying during high temperatures or strong winds. Prevent spray solution from reaching water sources. Keep away from children, animals, food, and feed. Do not reuse empty containers for other purposes. In severe or repeated cases, it is advisable to consult an agricultural engineer to determine an appropriate control program. Importance of the dual formulation in Pyrastak: Pyrastak combines Dimethomorph and Pyraclostrobin, two active substances from different groups. This combination enhances control efficiency, especially for diseases like late blight and powdery mildew that require early and organized intervention. Dimethomorph helps reduce the development of certain fungi associated with blights and powdery mildew, while Pyraclostrobin provides additional support within prevention and treatment programs. Thus, the product is suitable when the goal is to protect leaves and new growth and reduce disease spread within the field. Difference between preventive and therapeutic use of Pyrastak: Preventive use is before infection appears, especially when conditions favor fungal spread such as high humidity, dense planting, poor ventilation, or a history of previous infection. In this case, Pyrastak helps reduce the chances of disease initiation and spread. Therapeutic use is at the onset of first symptoms, such as blight spots or powdery mildew signs on leaves. The earlier the spraying, the better the chance of controlling the disease. In advanced infections, the crop may need an integrated program including regular repetitions and rotation among different fungal groups. Diseases that Pyrastak 45 SC helps control: Pyrastak 45 SC helps control several fungal diseases depending on the crop and recommendations, most notably: Late blight in potatoes. Late blight in tomatoes. Powdery mildew in grapes. Powdery mildew in cucumbers. Fungal diseases related to high humidity according to label recommendations. For broader options in plant disease control, refer to the section on fungicides or agricultural pesticides. Important advice for farmers: For the best results, it is recommended to use Pyrastak preventively before infection appears or at its early stages, and not to repeat its use alone in successive sprays. It is best to incorporate it into an integrated fungal control program based on rotation among different groups of fungicides, improving field ventilation, and reducing excess humidity as much as possible. It is also recommended to monitor the crop after spraying and evaluate disease development, as successful control depends not only on the fungicide but also on timing, coverage quality, infection severity, and overall plant condition.
