Control Methods and Technical Key Points for the Lychee Stink Bug
The lychee stink bug (Tessaratoma papillosa), belonging to Hemiptera, Pentatomidae, is a major pest of longan in our region. Both adults and nymphs pierce and suck the sap of tender shoots, flower clusters and young fruit; the damaged parts become discolored and dry up, causing flower and fruit drop. When disturbed, the foul liquid it emits touches tender leaves, flowers and fruit

Detailed Explanation of Spring Seed Propagation Methods for Honeysuckle
Pick the black fruits in January. After picking, pile them at a thickness of 30 cm and let them after-ripen for 5-7 days, then put them in clean water and rub and wash them to remove the peel and pulp, and dry them in a shady place. Avoid direct sun exposure, then winnow away the shriveled seeds and store them for later use. Seed treatment: before sowing, soak the seeds in warm water at 35-4

How to prevent litchi fruit cracking? Cultivation and control methods
1. Root pruning and girdling In the late stage of fruit development, the method of root pruning and girdling the main branches is used to weaken root activity, which is very effective in reducing fruit cracking. However, the measures must be timely and appropriate; excessive control of root growth is detrimental to normal fruit development and to the rapid recovery of tree vigor after harvest.

What are the control methods for grape leaf blight?
Symptoms: Brown spot disease is caused by infection with the fungus Pseudocercospora vitis, and mainly damages grape leaves. In the early stage of infection, the infection sites appear as light brown, irregular angular spots. The lesions gradually expand, reaching a diameter of up to 1 cm. The lesions change from light brown to brown, and then to reddish brown, with a

How should loquat be fertilized when grown? A detailed explanation of scientific fertilization methods for loquat
Loquat is an evergreen fruit tree that grows and bears fruit year-round without dormancy, so it requires more fertilizer than deciduous fruit trees. Fruiting trees in particular require more potassium. The types, amounts and timing of loquat fertilization should be combined with soil fertility, tree age, plant vigor, and the different growth stages of shoots and roots

Control Methods for Downy Mildew in Isatis indigotica (Dyer's Woad) Cultivation
Symptoms: On diseased leaves, yellowish-white lesions with rather indistinct edges appear on the leaf surface, gradually enlarge, and, constrained by the leaf veins, become polygonal or irregular in shape. On the corresponding underside grows a layer of grayish-white downy mildew-like substance, namely the pathogen's sporangiophores and sporangia exposed outside the host body.

Spring pruning methods for goji berry: prune properly for more fruit
1. Thinning branches. First, cut off dead branches, diseased and pest-infested branches, damaged branches, thorny branches and crossing branches, and then thin out overly dense fruiting branches. When thinning fruiting branches, first remove shaded branches, downward-facing branches and thin weak branches; then remove upward-facing branches and middle branches; if still dense, then thin the branches on both sides, cut

Control Methods and Technical Key Points for Litchi Downy Blight
Litchi downy blight can harm litchi from young fruit to ripe fruit, fruit stalks, and the small bearing branches; when humidity is high, leaves also develop the disease. Symptoms: local chlorosis on leaves, with white mold on the underside, the fruiting bodies of the pathogen, but usually at the peak period of this disease, the leaves have already aged, so leaf damage in the field is rarely seen.

Management Methods and Technical Key Points for Small Chili Peppers in the Middle and Late Stages
I. Land preparation and basal fertilizer application: Chili peppers should not be continuously cropped with solanaceous vegetables. Choose fields with deep soil, high organic matter content, loose soil, and good drainage for planting. Chili peppers have relatively high requirements for the three major nutrient elements: nitrogen, phosphorus, and potassium. Apply 3000--4000 kg of barnyard manure per mu as basal fertilizer,
