Plywood paint to trap micro pests Micro pests include aphids, whiteflies, and Liriomyza sativae. Do not look at them as they are small, but it is very difficult to deal with. For example, Liriomyza sativae is a master of tunneling, drilling into the leaves between the upper and lower skin hazards. The yellow plate trapping method is simple and easy. It means that after applying yellow-orange paint on both sides of the plywood, the paint is dry, and a layer of engine oil and butter mixed with viscous oil is used to coat and hang the middle of the orchard or other crops. "Eye" pests from the cast net, to achieve the desired trapping effect, one yellow area should be larger, each block is not less than 0.1 square meters, in order to increase its visibility and attractiveness; Second, the number is more, every 667 There must be no less than 30 square meters in order to get close to the catch; Third, the height of the hanging should be consistent with the height of the crop plants. The fourth is to change the sticky oil frequently. After hanging for a period of time, check the viscosity of the sticky oil. If the viscosity is found to be poor, apply another sticky oil.
The trunk of the trunk and the packaged insecticide of the aphid adopts the trunk package method to control the aphid, which generally takes effect after 3 days. The control effect can reach 100% in 5 days, and the control effect in 100 days can still be maintained in about 85%. Method is: in the fruit tree from the ground 20 cm to 30 cm in the main stem or base, select a section of about 15 cm wide smooth belt, scrape off the trunk rough skin, as the drug site. Put a ring of absorbent material on the chosen site (old cotton, toilet paper, used newspapers, etc.), then dilute 50% methamidophos or 40% omethoate into 3-5 times the injected pesticide. Or apply about 20 ml to the absorbent and tie it with a plastic film. The plastic film is released after the effect has appeared, and the absorbent is removed before the rain to prevent the dressing from rot.
Carbendazim Irrigating Roots Preventing fruit trees Flowing gum Fruit trees Flowing gum is a common disease in trees such as peach, plum, apricot, and cherry. It has caused tree-trends to decline, yields to fall, and the quality of the fruit to be low and heavy. Use 50% carbendazim wet powder 300 times to root, the effect is obvious. Specific methods: After the spring begins, when the sap begins to flow, the ridges around the diseased trees will be circled first, and the dosage of each tree will be determined according to the age of the trees. Generally, trees of 1 to 3 years old will each use 100 grams of trees. Larger 200 grams each, dilute to 300 times the amount of roots, flowering and fruiting, and then use the same amount of medicine to irrigate the roots once. In this case, when you encounter a rainy year, as long as the water is removed in time, the tree vigor can be restored. It will not happen.
