Maleic hydrazide (MH) avoids cell division in the apical meristem of plants; on the other hand, trinexapac-ethyl (TE) inhibits the biosynthesis of gibberellins, both reducing unwanted shoot growth (Fletcher et al., 2000).
Maleic hydrazide inhibits mitosis and meiosis in meristematic regions (Jabee et al., 2008).
Fruit yield per hectare in cucumber was found to be influenced positively by the application of lower concentrations of maleic hydrazide
, either alone or in combination with ethephon [21, 22].
Cytotoxicity and mode of action of maleic hydrazide in root tips of Allium cepa L.
Allium cepa anaphase-telophase root tip chromosome aberration assay on N-methyl-N-nitrosourea, maleic hydrazide, sodium azide, and ethyl methanesulfonate.
These range from determining alkaloid content via the spectrometric method; measuring maleic hydrazide
residues; assessing vapour phase nicotine and 3-ethenylpyridine in air through the gas-chromatographic method, and others.
is commonly applied to discourage offshoot growth.

Under the PIC procedure, dangerous substances or their preparations can only be exported with the advance consent of the importing country.According to the organisers of the Rome Conference, six new pesticides are also due to be added to the list of products covered by this measure.Delegates attending the Rome meeting also agreed to set up a committee to look into provisional chemicals and give its opinion on several other substances that have been singled out as hazardous: bromacil, dichloroethylene, ethylene oxide and maleic hydrazide
.Several countries taking part in the Rome Conference stressed the need for technical and financial assistance to help implement the procedure introduced by the Rotterdam Convention.
