What are the methods for controlling rice pests?
2.5% rotenone EC and other rotenone-cypermethrin patented series products are new plant-based insecticides developed to address two major problems in current agricultural production in China: pesticide-resistant pests and the frequent occurrence of food poisoning from pesticide residues. They have obtained a national invention patent and the Guangdong Provincial Science and Technology Progress Award. Large-scale trial demonstrations by plant protection experts in our province show that for controlling pesticide-resistant pests such as rice leaf roller (Cnaphalocrocis medinalis), rice planthopper, striped stem borer (Chilo suppressalis), armyworm, diamondback moth (Plutella xylostella), red spider mite, thrips, rust mite and scale insect, using a 1000

What are the control methods for rice brown spot?
Symptoms Also known as rice sesame leaf blight. It occurs in all rice-growing regions nationwide. Disease can occur from the seedling stage to the harvest stage, and all aboveground parts of the rice plant can be affected, with leaves being the most common. When seeds are affected at the germination stage, the coleoptile turns brown, the sprout fails to emerge, and the cotyledon dies. Leaf and leaf sheath disease at the seedling stage mostly appears as elliptical lesions, the size of sesame seeds, dark brown; sometimes the lesions enlarge and merge into strips, and when there are many lesions the seedlings die. On leaves of adult plants, infection begins as small brown spots, gradually enlarging into elliptical spots the size of sesame seeds, with the center of the lesion brown to grayish white, the margin brown, and around it yellow halos of varying

What are the control methods for zinc deficiency stunt seedling in rice?
Phosphorus deficiency stunt seedling generally occurs at the tillering stage after seedling recovery, manifesting as slow growth, short plants, slender and upright leaves, dark green leaf color, neat leaf cluster tips, significantly shortened leaf sheath distance, red tips on some tiller leaves, and brownish-red or even dead old leaves. Causes: first, the soil lacks available phosphorus; second, low soil temperature and water temperature, or the presence of reducing harmful substances such as hydrogen sulfide and ferrous iron in the soil, which reduces the root's absorption capacity; third, excessive application of nitrogen fertilizer, causing the effective nutrients to lose their relative balance. Control measures are based on the available phosphorus data measured by the "soil testing and fertilizer recommendation method"
