Mango tree insecticide and maintenance method for mango trees

Abstract

The invention relates to a mango tree insecticide, which comprises a fertilizer efficiency insecticide A and an insecticide B, wherein the insecticide A comprises potassium humate, glycolysis seaweedresidues, peat, borage, castor leaves, fermented bean meal and sea fish leftover fermentation hydrolysate, the insecticide B comprises weeping willow leaves, garlic stems and leaves, fresh ginger, illicium henryi roots, an organic solvent, fructus forsythiae and cortex meliae, the efficiency effect insecticide A has main effect of fertilizer efficiency providing and assisted effect of insect expelling and killing, and the insecticide B is mainly used for killing insects. According to the invention, the fertilizer efficiency insecticide A and the insecticide B are sequentially applied in the flower bud differentiation period, the flowering period, the fruit growth period and the maturation period of mango trees, the disease and pest resistance of the mango trees can be obviously improved, nutrients can be provided for the mango trees, the use of traditional compound fertilizers and insecticides is greatly reduced, the environment is protected, chemical residues are reduced, and the edible safety of mango fruits is improved.

Description

technical field [0001] The invention relates to the technical field of plant protection disease and insect pest control, in particular to an insecticide for mango trees and a maintenance method for mango trees. Background technique [0002] Mango is the king of tropical fruits, it contains a variety of vitamins, carotene, protein, carbohydrates, fat, sugar and other nutritional value. Eating properly can beautify the skin, prevent and treat high blood pressure, clear the stomach, and prevent constipation. For mango growers, mango pests have always been the most concerned and troublesome problem, such as pests and scale insects such as longhorn beetle and cross-haired moth, among which longhorn beetle eats branches and trunks with larvae It causes branches to dry out, broken branches or tree trunks to fold down; scale insects not only harm the branches and leaves of the crown of the tree, but also harm the fruit during the growth stage of mangoes, and suck the juice to repro...

AI Technical Summary

Problems solved by technology

The leaves often hide on the back, and the damaged parts turn yellow, which affects photosynthesis; the branches that are eaten are easy to lose water, and the tree vigor declines; the fruit is damaged, and the peel becomes rough. In severe cases, scale insects will secrete a large amount of honeydew. It is the best medium for the propagation of soot disease, and the commerciality of the fruit is greatly reduced; the cross-hair moth mainly damages the young shoots and flower spikes of mango, and eats the young shoots and flower spikes with larvae, causing the damaged parts to die, seriously affecting growth and production. Weaken tree vigor

Of course, mangoes will suffer from various pests during the planting and growth period. In the prior art, chemical pesticide reagents are mostly used to kill the above-mentioned pests. Chemical reagents will cause a large amount of pesticide residues while killing the living pests of mango trees, reducing the consumption of mangoes themselves. Moreover, mangoes are tropical plants, and rainy weather will bring pesticides into nearby rivers and groundwater. The above-mentioned side effects greatly limit the dosage and scope of chemical reagents
