August and September are critical months for the occurrence of pests and diseases in crops such as cotton, rice, and corn. This period is also essential for effective pest management. However, many middle-aged and elderly farmers have suffered economic losses due to improper pesticide use, crop damage, and environmental pollution during recent hot and dry weather conditions. The **Chinese Pesticide Network** has gathered scientific and practical methods to help farmers improve their pest control strategies. Here’s what you need to know:
First, avoid mixing or using pesticides on your own without proper guidance. Some combinations can reduce the effectiveness of pest control and may even harm sensitive parts of the plant, like cotton buds, flowers, and fruits. Also, some pesticides should not be used alone. Over-reliance on a single product can lead to resistance in pests, making it less effective over time. Based on experience, from August to September, it's best to alternate between different types of pesticides when managing pests in the later stages of cotton growth.
Second, don’t use pesticides blindly without understanding their purpose or effectiveness. Some products are only suitable for specific crops; using them on others may not work and could cause harm. Always treat the disease according to its severity and follow the correct dosage. For example, during the second season, for the third generation of late rice, three generations of mites, and four generations of aphids, the recommended mixture includes 50 ml of emulsifiable concentrate per acre, 30 grams of 901 synergist, 50 grams of a wetting agent, and 100 kg of water. Apply this solution in the late afternoon, around 4 o’clock, and you’ll see significant results.
Third, timing is crucial. During August and September, pests like the red bollworm, cotton bollworm, Spodoptera litura, rice leaf roller, locusts, and planthoppers are most active in the evening or on cloudy days. When dealing with the fourth generation of Sanhuan or the third generation of aphid "sucking white ears," farmers should target the best time—when dew is still on the leaves.
Fourth, don’t abuse pesticides. Recently, I saw some farmers ignoring the instructions and increasing the concentration arbitrarily, while others relied solely on old habits. As you might know, adjusting concentrations without guidance increases costs and harms natural predators of pests. This can lead to an explosion in pest populations, causing even more damage in a short time.
The **Pesticide Network** reminds all farmers that before applying any treatment, it’s essential to understand the right way to use the product. Doing so not only improves effectiveness but also ensures safer and more sustainable farming practices. Always read the label, follow the guidelines, and make informed decisions.
A pneumatic hydraulic jack is a mechanical device that uses air pressure to generate force and lift heavy objects. It cosists of a cylinder and filled with compressed air, a piston that moves up and down inside the cylinder, and a hydraulic system that converts the air pressure into hydrauli force. When the jack is activated, the compressed air pushes the piston, which in turn pushes hydraulic fluid through a series of valves and pipes, creating a force that lifts the load. The jack is commonly used in automotive and industrial applications for lifting vehicles and heavy machinery.
