What are the scientific methods for using bacterial biological insecticides?
From rice sowing to the seedling stage, farmers should focus on controlling seed-borne diseases (bakanae disease, rice blast at the seedling stage, white-tip nematode disease, etc.), the small brown planthopper, and the first-generation stem borers. At the rice booting stage, the focus should be on controlling pests and diseases such as the rice planthopper, rice leaf roller, stem borers, ear blast, and rice false smut. At the rice ear stage, the rice planthopper is the main target, along with...

Detailed Explanation of Key Points for Using Bacterial Biological Insecticides
Bacterial biological insecticides have advantages such as high insecticidal rate, no environmental pollution, safety to natural enemies, harmlessness to humans and livestock, and not inducing pest resistance. They are a new type of protective pesticide currently promoted for use in pollution-free cultivation. Because their control effect mainly depends on the bacterial activity in the pesticide, the following points need to be kept in mind during use...

Six key taboos to remember when using bacterial biological insecticides
Edible fungi suffer pest damage during the mycelium growth and mushroom fruiting stages due to the distinctive odor of the mycelium, so insecticides are often used when pest damage occurs. When pest damage occurs in edible fungi, the first step is to choose insecticides that are highly effective, low in toxicity, and have a short residual life, such as decis and dichlorvos; do not use banned substances such as benzene hexachloride (BHC) and DDT...

Navel Orange Cultivation Techniques: How to Prevent and Control Physiological Diseases of Navel Oranges?
How to prevent and control physiological diseases of navel oranges? Please provide an introduction. The main physiological diseases of navel oranges are fruit cracking, sunburn, and navel yellowing. For control methods, please refer to the following list: Control methods for navel orange fruit cracking. For navel orange fruit cracking, first select varieties (lines) with strong cracking resistance. Generally, varieties (lines) with oval fruit shape, small navel or closed navel have better cracking resistance, such as Newhall and others. Second, strengthen scientific management to enhance tree vigor. Especially during the drought period after the plum rain and before the autumn rains arrive, water management must be done particularly well, with timely irrigation or watering (sprinkling) to keep the soil moist and promote normal fruit growth and development. Third, during the rapid fruit expansion period, spray foliar potassium fertilizer 2 to 3 times consecutively.
