Bordeaux liquid use points

1. Bordeaux mixture is a preventive fungicide and is usually sprayed before the onset of illness.

2. Plant growth period is different, the concentration of drug is not the same. Generally, the organs in the early stage of plant growth are delicate, the drug resistance is poor, and the concentration should be lower.

3. Different proportions should be used according to plant variety, target, season and temperature. Such as roses, jellyfish and other susceptible to copper damage, should be used in equal or multi-type; in high temperature and arid climate, Solanaceae and Cucurbitaceae flowers are susceptible to lime phytotoxicity, using half or a small amount; After spreading the leaves, the leaves are susceptible to phytotoxicity and cannot be used. If necessary, the same amount can be used after the winter leaves or before the early spring germination.

4. If it is self-made, it should be used now. The storage period should not exceed 24 hours. For example, adding 0.2 to 0.3% of filtered soy milk or rice soup during preparation can improve the adhesion. It is not advisable to spray at high temperature at noon, otherwise it may cause phytotoxicity. It is best to spray on the sunny evening.

5. Can not be mixed with soap, rosin mixture and alkali decomposition agent, but can not be mixed with stone sulphur mixture, otherwise it will easily produce copper sulphide precipitation, which will invalidate the two drugs and cause phytotoxicity. Plants that have used stone sulphur mixture cannot use Bordeaux mixture for 30 days.

6. The raw materials used to prepare the Bordeaux mixture must be of good quality. When copper is used in Bordeaux mixture, 0.5 to 1% of lime milk can be sprayed, and lime poison should be reduced.
