What pesticide gives the best control effect against older larvae of the rice leaf roller?
Chlorpyrifos and abamectin-monosultap are effective agents for controlling the rice leaf roller, but they must be applied during the 1st-2nd instar young larval stage (at this stage the rice leaf roller has not yet rolled leaves and caused damage, or has just begun rolling the leaf tips and causing damage), when the rice in the field has just begun to roll leaves. For rice leaf roller larvae of the 3rd instar and above, on the one hand they are protected because they are wrapped inside the rice leaves, and on the other hand they are insensitive to nereistoxin-type pesticides such as monosultap and to organophosphorus pesticides such as chlorpyrifos, methamidophos and monocrotophos, so the control effect after spraying is poor. Relatively speaking, older rice leaf

Can emamectin benzoate control the rice leaf roller?
Emamectin benzoate is a new type of high-efficiency semi-synthetic antibiotic insecticide synthesized starting from the fermentation product avermectin B1. It has the characteristics of biological pesticides such as ultra-high efficiency, low toxicity (the formulation is nearly non-toxic), no residue, and no pollution. Compared with avermectin, its insecticidal activity is first increased by 1-3 orders of magnitude. It has extremely high activity against the larvae of Lepidoptera insects and many other pests and mites. It has both stomach poison action and contact action, and has very good effects at very low doses (0.084~2g/ha), and in the process of controlling pests it is harmless to beneficial

How to Prevent Dry, Brown Leaf Tips on Spider Plants and Care Tips
When spider plants (Chlorophytum comosum) are grown in pots at home, they often develop dry leaf tips and gradually lose their glossy sheen. To keep a spider plant in good condition, take the following measures: Change the soil and repot. To keep the stems and leaves lush, change the soil and repot once every year in March. If the pot is fairly deep and the base fertilizer is sufficient, you can repot once every two years. When repotting, knock the plant out of the pot, cut off the dead and rotten roots and excess rootlets, replace with fresh humus-rich potting soil, and apply pieces of livestock hoof and horn or decomposed cake fertilizer as a base fertilizer. After planting, place it

Loose leaf tea can be dried by sun-drying or oven-drying.
The use of tea began with chewing the fresh leaves of the tea plant, and later developed into boiling the fresh leaves into a soup-like drink; in both cases the fresh leaves of the tea plant were used directly. Before the Tang Dynasty, tea processing was relatively simple: the freshly picked leaves were sun-dried or oven-dried and then stored away. This was the budding stage of the sun-dried green tea process.

Detailed Explanation of the Processing Method and Production Steps of Persimmon Leaf Tea
Persimmon leaf tea is a new product of scientific research. It is not only very popular among domestic consumers, but is also exported to Japan. This is mainly because the leaves of persimmon trees and soft jujube trees have high nutritional value. Every 100 grams of fresh leaves contains about 100 mg of vitamin C, and if dried leaves, it is as high as 3500 mg; in addition, they also contain large amounts of rutin, carotene, choline, flavonoid glycosides, amino acids, etc., which can refresh the mind and improve eyesight, reduce inflammation and relieve fever, cool the blood, stop bleeding and lower blood pressure, and can also increase coronary blood flow in the heart, and have a certain effect on preventing and treating cancers of the digestive system. The production method of persimmon leaf tea is as follows:

Rice seedlings turning yellow, leaves curling, leaf-rolling: what to do? A detailed guide to prevention and control
There are many causes of the rice leaf-rolling phenomenon, and the most common one is the rice leaf roller (Cnaphalocrocis medinalis). Damage characteristics: the larvae bind silk to roll rice leaves lengthwise into larval cases, and the larvae hide inside and feed on the mesophyll, leaving only the epidermis, forming white streaks, which reduces the 1000-grain weight of rice, increases empty grains, and causes yield loss. Control agents: 1. Select rice varieties resistant to (or tolerant of) the pest, fertilize reasonably, so that the rice grows and develops vigorously, and prevent excessive early growth and excessive tillering as well as late-season stay-green and delayed maturity. Manage water scientifically, adjust the drainage (field-drying) time appropriately, and reduce field humidity during the larval hatching period

What to Do About Brown Leaf Tips on Chinese Cymbidium Leaves? A Detailed Guide to Prevention and Treatment
Orchid leaves grow vigorously, green and sturdy, with graceful leaf posture and spirited form, delighting the eye. If the leaf tips are scorched and the leaves withered, covered in spots like patches of psoriasis, even a rare and extraordinary flower will be greatly diminished. To grow good orchid leaves, I made improvements in the following six areas. 1. The potting soil must be breathable, well-draining, and moisture-retentive. It should have good crumb structure, soft and loose, like a sponge, with medium fertility; leaf mold from the mountains or peat soil is best. If you cannot get these in the city, mix your own nutrient soil. The formulas are: (1) 8 parts spent mushroom substrate, half a part of honeycomb coal ash,
