Nowadays, the season of using fruit tree herbicides is different. Different apple trees have different sensitivity to herbicides. If the method is improperly used, it is easy to cause phytotoxicity. Therefore, it is not uncommon for fruit trees to fall and fall. Let's take a look at the following. Let's go.
1. If the green huanglong is applied in the peach tree garden, the residual effect period of the drug is long, and the agent is dissolved and absorbed into the ground and absorbed by the root system, causing the roots of the peach tree to be necrotic, causing the growth to be bad, and serious damage to the garden.
2. Atrazine (Atsujin) is sensitive to peaches and is susceptible to phytotoxicity. In particular, it cannot be used on peach seedlings and juvenile peach trees.
3. Simazine is applied to fruit tree nurseries and seedlings, and it is also prone to phytotoxicity. It is not advisable to apply sensitive crops such as beans and melons to the orchard.
4. Banana seedlings are sensitive to glyphosate. Be careful when spraying, and prevent drifting and contact with nearby pears, citrus, grape branches, leaves, etc., as well as the trunk of young trees to protect them from phytotoxicity.
5. The grapes grown by Diuron in sandy soil and gravel soil should not be applied, otherwise the phytotoxicity will be more serious. In the application of pineapple garden, the roots and stems of pineapple are used after repeated use of diuron due to long residual effect period. There are residues in other parts, so other types of herbicides should be selected or used alternately with other herbicides to minimize the occurrence of phytotoxicity.
6, strawberry weeding, if the use of 2,4-D butyl ester weeding, will cause strawberry plants drooping, wilting, old leaves fall off, the entire plant died, causing irreparable damage.
7. Ligulong liquid can not be sprayed onto the leaves and fruits of fruit trees, and the herbicides can not be used in sandy soils and long-term dry fruit trees. In addition, the drugs such as dysentery and 2,4-D butyl ester are prominently harmful, especially in the morning foggy weather. The droplets of these two herbicides will drift with the fog, causing damage to the orchard and falling flowers. Falling leaves and fruit, this kind of drifting phytotoxicity generally occurs in a wide range and is worthy of attention.
